EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing. Nice in solid drawmode! Further some small additional fixes in the whole debugging process. Found old error in loopselect for triangles, subdivision code, and selection still. NOTE: subdivide still works on vertex level only.

Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it).

A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well.

If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing. Nice in solid drawmode! Further some small additional fixes in the whole debugging process. Found old error in loopselect for triangles, subdivision code, and selection still. NOTE: subdivide still works on vertex level only.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now.

Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it).

Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

For example when you just extrude 1 edge, it uses normal grabber. Note; extruding an entire sphere goes OK with 'individual faces'. for other extrudes you should press 's key' when in transform.

For example when you just extrude 1 edge, it uses normal grabber. Note; extruding an entire sphere goes OK with 'individual faces'. for other extrudes you should press 's key' when in transform. Just cannot predict (yet) when one method has preference over another.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing. Nice in solid drawmode! Further some small additional fixes in the whole debugging process. Found old error in loopselect for triangles, subdivision code, and selection still. NOTE: subdivide still works on vertex level only.

Recoded how 'handles' were implemented; these were extra wireframe edges actually, adding vertices and edges to displist. Now the subsurfer gives editvertices a pointer to the subsurfed vertex location; allowing not only vertices in 'optimal' draw to show correct, but also gives proper handling of borderselect and lasso for edges. :)

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it).

Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing. Nice in solid drawmode! Further some small additional fixes in the whole debugging process. Found old error in loopselect for triangles, subdivision code, and selection still. NOTE: subdivide still works on vertex level only.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing.

New: Fake Polygons, or Face-polygons, or FGons nicked for now. Just select a bunch of faces (selection should be valid flat poly) and press FKEY. Works in fact as selection-group optimizing. Nice in solid drawmode! Further some small additional fixes in the whole debugging process. Found old error in loopselect for triangles, subdivision code, and selection still. NOTE: subdivide still works on vertex level only.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it).

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture.

Two fixes; - The function "convex()" in editmesh_lib() actually did not deliver a proper test for convex at all. It was checking only if a quad could be subdivided into 2 trias. Code for adding face (FKEY) used this call in total confusing manner. That code was there in 1.40 already, cannot find any clue what it was supposed todo... :) Recoded convex() to deliver a proper test. FKEY will give warning on attempt to make convex faces now. - Added undo-free for editmode undo on file load

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

Two fixes; - The function "convex()" in editmesh_lib() actually did not deliver a proper test for convex at all. It was checking only if a quad could be subdivided into 2 trias. Code for adding face (FKEY) used this call in total confusing manner. That code was there in 1.40 already, cannot find any clue what it was supposed todo... :) Recoded convex() to deliver a proper test. FKEY will give warning on attempt to make convex faces now. - Added undo-free for editmode undo on file load

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

static void edge_rotate(EditEdge *eed,int dir)
EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.
2004-09-23 20:52:51 +00:00
Suggested by bug reporter; pressing Fkey to make a face, whilst the selection already is 2 triangles, it should create a new face but remove the old triangles. It actually calls the 'ALT+J' command then (join triangles) While testing found out more cases where new selection flags were not properly used (join trias, beauty fill, flip edges, rotate edges)

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.

EditMesh refactory + undo recode The changelog is very long... it's on the web too: http://www.blender3d.org/cms/Mesh_editing_rewrite.425.0.html EditMesh refactor notes (user) **** New selection modes When entering Edit Mode for a Mesh, you now have the choice for three selection modes. These are shown as icons in the 3D header (hotkey is being searched for!). - Vertex Select Select vertices as usual, fully compatible with how previous version work - Edge Select Vertices are not drawn anymore, and selections happen by default on the edges. It is a true edge select, meaning that you can select three out of four edges in a face, without automatic having the 4th edge selected. - Face Select Instead of vertices, now selection 'points' are drawn in the face centers. Selected faces also get a colored outline, like for edges. This also is true face select, for each face individual regardless selection status of its vertices or edges. While holding SHIFT, and press a selection mode, you can also combine the above choices. Now selection becomes mixed, and will behave as expected. For example; in Edge+Face select mode, selecting the 4 edges of a face will select the face too. The selection modes and optional drawing modes (like transparant faces, normals, or solid drawing) all work together. All of Blender's mesh editing tools now react to the correct selection mode as well. Most noticeable it's in: **** Extrude Extruding in Edge or Face Select mode allows much more precise control over what's extruded and what should be excluded. Try for example a checker pattern selection, and extrude it. New is the fixed translation when faces are extruded. This always follows the (averaged) face normal(s) of the old face(s), enabling much easier working in 3D views . A single 'G' (Grab) or 'R' (Rotate) or 'S' (Scale) will change transform modus as usual. **** Other things to note - Hiding edges/faces will also behave different based on Select Mode. - while editing, normals of faces are updated always now - Border select (BKEY) has 2 different rules for edges; when one edge is fully inside of the border, it will only select edges that are fully inside. Otherwise it selects each edge intersecting with the border. - in face mode, adding vertices, edges or a circle is invisible... - "Add monkey" now works as a normal primitive (rotated and on 3d cursor) - Mesh undo was fully recoded, hopefully solving issues now with Vertex Keys and Groups - Going in and out of editmode was fully recoded. Especially on larger models you'll notice substantial speed gain. **** Todo Add 'FaceSelect mode' functionality in EditMode, including zbuffered selection, display and editing of UV texture. EditMesh refactor notes (coder) **** Usage of flags in general The "->f" flags are reserved for the editmesh.c and editmesh_lib.c core functions. Actually only selection status is there now. The "->f1" and "->f2" flags are free to use. They're available in vertex/edge/face structs. Since they're free, check carefully when calling other functions that use these flags... for example extrude() or subdivide() use them. **** Selection flags EditVert: eve->f & SELECT EditEdge: eed->f & SELECT EditFace: efa->f & SELECT - Selection is only possible when not-hidden! - Selection flags are always up-to-date, BUT: if selection mode >= SELECT_EDGE vertex selection flags can be incorrect if selection mode == SELECT_FACE vertex/edge selection flags can be incorrect This because of shared vertices or edges. - use for selecting vertices: eve->f &= SELECT - use for selecting edges always: void EM_select_edge(eed, 1) // 1 = select, 0 = deselect - use for selecting faces always: void EM_select_face(efa, 1) // 1 = select, 0 = deselect - To set the 'f' flags in all of the data: void EM_set_flag_all(int flag); void EM_clear_flag_all(int flag); - the old faceselectedOR() and faceselectedAND() are still there, but only to be used for evaluating its vertices **** Code hints for handling selection If the selectmode is 'face'; vertex or edge selections need to be flushed upward. Same is true for 'edge' selection mode. This means that you'll have to keep track of all selections while coding... selecting the four vertices in a face doesn't automatically select the face anymore. However, by using the above calls, at least selections flush downward (to vertex level). You then can call: void EM_selectmode_flush(void); Which flushes selections back upward, based on the selectmode setting. This function does the following: - if selectmode 'vertex': select edges/faces based on its selected vertices - if selectmode 'edge': select faces based its selected edges This works fine in nice controlled situations. However, only changing the vertex selections then still doesn't select a face in face mode! If you really can't avoid only working with vertex selections, you can use this call: void EM_select_flush(void); Now selection is flushed upward regardless current selectmode. That can be destructive for special cases however, like checkerboard selected faces. So use this only when you know everything else was deselected (or deselect it). Example: adding primitives. **** Hide flags EditVert: eve->h EditEdge: eed->h EditFace: efa->h - all hide flags are always up-to-date - hidden vertices/edges/faces are always deselected. so when you operate on selection only, there's no need to check for hide flag. **** Unified undo for editmode New file: editmode_undo.h A pretty nice function pointer handler style undo. Just code three functions, and your undo will fly! The c file has a good reference. Also note that the old undo system has been replaced. It currently uses minimal dependencies on Meshes themselves (no abuse of going in/out editmode), and is restricted nicely to editmode functions. **** Going in/out editmode As speedup now all vertices/faces/edges are allocated in three big chunks. In vertices/faces/edges now tags are set to denote such data cannot be freed. ALso the hashtable (lookup) for edges uses no mallocs at all anymore, but is part of the EditEdge itself.
