#include "string.h"
- modifier UI update (aka, find the modifier buttons!!) - moved back to editing buttons, where life is now cramped... switched to constraint style foldout panes, still a WIP. In particular not sure what buttons should be in header (and if current toggles stay in header if they should also be in an expanded pane). Also need new icons for move up/move down (and drag and drop would of course be nice). Finally current plane is to make it so modifiers will expand out in modifier pane for horizontal orientations instead of just going down down down to goblin town. - added error field to modifiers that is displayed in UI, need to have some way for modifiers to return errors back to interface (esp. important for python) - tweaked cage determination and handling, currently the editmode cage is determined by last modifier with OnCage set that is preceeded completely by modifiers that support mapping or are disabled in editmode. it is kinda confusing, but the interface only lets you toggle OnCage for modifiers that support it - it just might not be clear all the time why you can't toggle a certain modifier OnCage. - update displistmesh_copy to only copy edges if non-NULL There is a display bug that already existed but is more obvious with new modifiers where parts of the pane get drawn in a different area after toggling editmode. It has to do with drawing parts of the interface using GL instead of 100% buttons. I try to keep my grubby little toes out of the interface code so this can wait for Ton to return.

- added data arguments to deformer modifiers, in case someone wants to write one that is based on geometry (and not just vertex position) - added editmode versions of modifier deform/apply calls and flag to tag modifiers that support editmode - added isFinalCalc param to applyModifier, basically a switch to let subsurf know if it is calc'ng orco or not (so it can deal with cache appropriately). This is kinda hacky and perhaps I can come up with a better solution (its also a waste to do a complete subdivide just to get vertex locations). - changed ccgsubsurf to not preallocate hash's to be approximately correct size... this was probably not a big performance savings but means that the order of faces returned by the iterator can vary after the first call, this messes up orco calculation so dropped for time being. - minor bug fix, meshes with only key didn't get vertex normals correctly calc'd - updated editmesh derivedmesh to support auxiliary locations - changed mesh_calc_modifiers to alloc deformVerts on demand - added editmesh_calc_modifiers for calculating editmesh cage and final derivedmesh's - bug fix, update shadedisplist to always calc colors (even if totvert==0) - changed load_editMesh and make_edge to build me->medge even if totedge==0 (incremental subsurf checks this) todo: add drawFacesTex for ccgderivedmesh So, modifiers in editmode are back (which means auto-mirror in edit mode works now) although still not finished. Currently no cage is computed, the cage is always the base mesh (in other words, Optimal edge style editing is off), and the final mesh currently includes all modifiers that work in edit mode (including lattice and curve). At some point there will be toggles for which modifiers affect the final/cage editmode derivedmesh's. Also, very nice new feature is that incremental subsurf in object mode returns a ccgderivedmesh object instead of copying to a new displistmesh. This can make a *huge* speed difference, and is very nice for working with deformed armatures (esp. with only small per frame changes).

- shuffled editmesh derived function name/function - added ModifierTypeInfo.freeData function - added modifier_{new,free] utility function - added ccgSubSurf_getUseAgeCounts to query info - removed subsurf modifier faking (ME_SUBSURF flag is no longer valid). subsurf modifier gets converted on file load although there is obscure linked mesh situation where this can go wrong, will fix shortly. this also means that some places in the code that test/copy subsurf settings are broken for the time being. - shuffled modifier calculation to be simpler. note that all modifiers are currently disabled in editmode (including subsurf). don't worry, will return shortly. - bug fix, build modifier didn't randomize meshes with only verts - cleaned up subsurf_ccg and adapted for future editmode modifier work - added editmesh.derived{Cage,Final}, not used yet - added SubsurfModifierData.{mCache,emCache}, will be used to cache subsurf instead of caching in derivedmesh itself - removed old subsurf buttons - added do_modifiers_buttons to handle modifier events - removed count_object counting of modifier (subsurfed) objects... this would be nice to add back at some point but requires care. probably requires rewrite of counting system. New feature: Incremental Subsurf in Object Mode The previous release introduce incremental subsurf calculation during editmode but it was not turned on during object mode. In general it does not make sense to have it always enabled during object mode because it requires caching a fair amount of information about the mesh which is a waste of memory unless the mesh is often recalculated. However, for mesh's that have subsurfed armatures for example, or that have other modifiers so that the mesh is essentially changing on every frame, it makes a lot of sense to keep the subsurf'd object around and that is what the new incremental subsurf modifier toggle is for. The intent is that the user will enable this option for (a) a mesh that is currently under active editing or (b) a mesh that is heavily updated in the scene, such as a character. I will try to write more about this feature for release, because it has advantages and disadvantages that are not immediately obvious (the first user reaction will be to turn it on for ever object, which is probably not correct).

- shuffled editmesh derived function name/function - added ModifierTypeInfo.freeData function - added modifier_{new,free] utility function - added ccgSubSurf_getUseAgeCounts to query info - removed subsurf modifier faking (ME_SUBSURF flag is no longer valid). subsurf modifier gets converted on file load although there is obscure linked mesh situation where this can go wrong, will fix shortly. this also means that some places in the code that test/copy subsurf settings are broken for the time being. - shuffled modifier calculation to be simpler. note that all modifiers are currently disabled in editmode (including subsurf). don't worry, will return shortly. - bug fix, build modifier didn't randomize meshes with only verts - cleaned up subsurf_ccg and adapted for future editmode modifier work - added editmesh.derived{Cage,Final}, not used yet - added SubsurfModifierData.{mCache,emCache}, will be used to cache subsurf instead of caching in derivedmesh itself - removed old subsurf buttons - added do_modifiers_buttons to handle modifier events - removed count_object counting of modifier (subsurfed) objects... this would be nice to add back at some point but requires care. probably requires rewrite of counting system. New feature: Incremental Subsurf in Object Mode The previous release introduce incremental subsurf calculation during editmode but it was not turned on during object mode. In general it does not make sense to have it always enabled during object mode because it requires caching a fair amount of information about the mesh which is a waste of memory unless the mesh is often recalculated. However, for mesh's that have subsurfed armatures for example, or that have other modifiers so that the mesh is essentially changing on every frame, it makes a lot of sense to keep the subsurf'd object around and that is what the new incremental subsurf modifier toggle is for. The intent is that the user will enable this option for (a) a mesh that is currently under active editing or (b) a mesh that is heavily updated in the scene, such as a character. I will try to write more about this feature for release, because it has advantages and disadvantages that are not immediately obvious (the first user reaction will be to turn it on for ever object, which is probably not correct).

This also means that mirror interacts much better with incremental subsurf calculation (it used to recalc one entire side on any topology change, now it generally avoids that). - added EM_{init,free}_index_arrays and EM_get_{vert,edge,face}_for_index functions to handle mapping indices back into appropriate EditMesh structures. - bug fix, make edges didn't recalc object data - bug fix, initial image assignment to TFace's didn't recalc object data - new feature, added circle select support for FACESELECT - bug fix, creating new faces in editmode duplicated the TFACE active flag - but there should only be one active tface - bug fix, possible crash when deleting all faces in faceselect mode on mesh with tfaces...

- convert all DerivedMesh map functions to use index based mapping (instead of Edit{Vert,Edge,Face} pointers) - dropped convertToDispListMeshMapped (whew, glad of it too) - added DerivedMesh drawMappedFaces function - dropped EM suffix for DerivedMesh functions, it was neither particularly correct nor descriptive - converted test_index_mface to test_index_face that also corrects MCol and TFace. Good thing we had three versions of this routine, you never know when one might burn down. - removed flipnorm_mesh, not used anymore (and was incorrect to boot) - Getting face select to work with modifiers turned out to be much more complicated than expected. Reworked mapping architecture for modifiers - basically elements in a DispListMesh are now required to be stored in an order that corresponds exactly to original ordering. MVert/MEdge/MFace all have a new flag ME_XXX_STEPINDEX that is set on each element that is set on the first derived element of each original element. I can't say the code to follow these requirements for subsurf is particularly transparent, but on the upside it is a reasonably consistent and simple system that is memory efficient and allows keeping the DispListMesh structure. - rewrote mirror modifier to be simpler/conform to new requirements for mapped DispListMesh structure. This also means that mirror interacts much better with incremental subsurf calculation (it used to recalc one entire side on any topology change, now it generally avoids that). - added EM_{init,free}_index_arrays and EM_get_{vert,edge,face}_for_index functions to handle mapping indices back into appropriate EditMesh structures. - bug fix, make edges didn't recalc object data - bug fix, initial image assignment to TFace's didn't recalc object data - new feature, added circle select support for FACESELECT - bug fix, creating new faces in editmode duplicated the TFACE active flag - but there should only be one active tface - bug fix, possible crash when deleting all faces in faceselect mode on mesh with tfaces... Still todo: TFace edge drawing is still not always correct in face mode, in particular with a mirror modifier when mesh has edges (and no preceeding subsurf). Have not yet decided how to deal with this. Best solution is probably to do switch to meshes all having MEdge's, in which case I can get rid of TFace edge flags (and need to recalc modifiers on tface selection change).

Currently no cage is computed, the cage is always the base mesh (in other words, Optimal edge style editing is off), and the final mesh currently includes all modifiers that work in edit mode (including lattice and curve). At some point there will be toggles for which modifiers affect the final/cage editmode derivedmesh's. Also, very nice new feature is that incremental subsurf in object mode returns a ccgderivedmesh object instead of copying to a new displistmesh.

This also means that mirror interacts much better with incremental subsurf calculation (it used to recalc one entire side on any topology change, now it generally avoids that). - added EM_{init,free}_index_arrays and EM_get_{vert,edge,face}_for_index functions to handle mapping indices back into appropriate EditMesh structures. - bug fix, make edges didn't recalc object data - bug fix, initial image assignment to TFace's didn't recalc object data - new feature, added circle select support for FACESELECT - bug fix, creating new faces in editmode duplicated the TFACE active flag - but there should only be one active tface - bug fix, possible crash when deleting all faces in faceselect mode on mesh with tfaces... Still todo: TFace edge drawing is still not always correct in face mode, in particular with a mirror modifier when mesh has edges (and no preceeding subsurf). Have not yet decided how to deal with this. Best solution is probably to do switch to meshes all having MEdge's, in which case I can get rid of TFace edge flags (and need to recalc modifiers on tface selection change).

- added data arguments to deformer modifiers, in case someone wants to write one that is based on geometry (and not just vertex position) - added editmode versions of modifier deform/apply calls and flag to tag modifiers that support editmode - added isFinalCalc param to applyModifier, basically a switch to let subsurf know if it is calc'ng orco or not (so it can deal with cache appropriately). This is kinda hacky and perhaps I can come up with a better solution (its also a waste to do a complete subdivide just to get vertex locations). - changed ccgsubsurf to not preallocate hash's to be approximately correct size... this was probably not a big performance savings but means that the order of faces returned by the iterator can vary after the first call, this messes up orco calculation so dropped for time being. - minor bug fix, meshes with only key didn't get vertex normals correctly calc'd - updated editmesh derivedmesh to support auxiliary locations - changed mesh_calc_modifiers to alloc deformVerts on demand - added editmesh_calc_modifiers for calculating editmesh cage and final derivedmesh's - bug fix, update shadedisplist to always calc colors (even if totvert==0) - changed load_editMesh and make_edge to build me->medge even if totedge==0 (incremental subsurf checks this) todo: add drawFacesTex for ccgderivedmesh So, modifiers in editmode are back (which means auto-mirror in edit mode works now) although still not finished. Currently no cage is computed, the cage is always the base mesh (in other words, Optimal edge style editing is off), and the final mesh currently includes all modifiers that work in edit mode (including lattice and curve). At some point there will be toggles for which modifiers affect the final/cage editmode derivedmesh's. Also, very nice new feature is that incremental subsurf in object mode returns a ccgderivedmesh object instead of copying to a new displistmesh. This can make a *huge* speed difference, and is very nice for working with deformed armatures (esp. with only small per frame changes).

- added data arguments to deformer modifiers, in case someone wants to write one that is based on geometry (and not just vertex position) - added editmode versions of modifier deform/apply calls and flag to tag modifiers that support editmode - added isFinalCalc param to applyModifier, basically a switch to let subsurf know if it is calc'ng orco or not (so it can deal with cache appropriately). This is kinda hacky and perhaps I can come up with a better solution (its also a waste to do a complete subdivide just to get vertex locations). - changed ccgsubsurf to not preallocate hash's to be approximately correct size... this was probably not a big performance savings but means that the order of faces returned by the iterator can vary after the first call, this messes up orco calculation so dropped for time being. - minor bug fix, meshes with only key didn't get vertex normals correctly calc'd - updated editmesh derivedmesh to support auxiliary locations - changed mesh_calc_modifiers to alloc deformVerts on demand - added editmesh_calc_modifiers for calculating editmesh cage and final derivedmesh's - bug fix, update shadedisplist to always calc colors (even if totvert==0) - changed load_editMesh and make_edge to build me->medge even if totedge==0 (incremental subsurf checks this) todo: add drawFacesTex for ccgderivedmesh So, modifiers in editmode are back (which means auto-mirror in edit mode works now) although still not finished. Currently no cage is computed, the cage is always the base mesh (in other words, Optimal edge style editing is off), and the final mesh currently includes all modifiers that work in edit mode (including lattice and curve). At some point there will be toggles for which modifiers affect the final/cage editmode derivedmesh's. Also, very nice new feature is that incremental subsurf in object mode returns a ccgderivedmesh object instead of copying to a new displistmesh. This can make a *huge* speed difference, and is very nice for working with deformed armatures (esp. with only small per frame changes).

However, for mesh's that have subsurfed armatures for example, or that have other modifiers so that the mesh is essentially changing on every frame, it makes a lot of sense to keep the subsurf'd object around and that is what the new incremental subsurf modifier toggle is for. The intent is that the user will enable this option for (a) a mesh that is currently under active editing or (b) a mesh that is heavily updated in the scene, such as a character. I will try to write more about this feature for release, because it has advantages and disadvantages that are not immediately obvious (the first user reaction will be to turn it on for ever object, which is probably not correct).

- modifier UI update (aka, find the modifier buttons!!) - moved back to editing buttons, where life is now cramped... switched to constraint style foldout panes, still a WIP. In particular not sure what buttons should be in header (and if current toggles stay in header if they should also be in an expanded pane). Also need new icons for move up/move down (and drag and drop would of course be nice). Finally current plane is to make it so modifiers will expand out in modifier pane for horizontal orientations instead of just going down down down to goblin town. - added error field to modifiers that is displayed in UI, need to have some way for modifiers to return errors back to interface (esp. important for python) - tweaked cage determination and handling, currently the editmode cage is determined by last modifier with OnCage set that is preceeded completely by modifiers that support mapping or are disabled in editmode. it is kinda confusing, but the interface only lets you toggle OnCage for modifiers that support it - it just might not be clear all the time why you can't toggle a certain modifier OnCage. - update displistmesh_copy to only copy edges if non-NULL There is a display bug that already existed but is more obvious with new modifiers where parts of the pane get drawn in a different area after toggling editmode. It has to do with drawing parts of the interface using GL instead of 100% buttons. I try to keep my grubby little toes out of the interface code so this can wait for Ton to return.

New: CrazySpace [tm] correction When Modifiers are used in Edit Mode to show the deformed result for editing, all actual coordinates Blender works with are still the ones from the original Cage. You can notice that with the Transform Widget or helper lines while transforming. Even worse, the actual transformations still happened on the original Cage as well, making it very hard to edit. That caused the feature to be named "CrazySpace" (baptized by Andy, afaik?). This commit calculates the deformation transformation per vertex, and inverse corrects it, so it's more intuitive editing this way. Unfortunately all the deformation features of Blender don't use matrices for defining deform, so the existing code cannot be re-used to retrieve the correct deformation matrix per vertex. The solution I found is based on calculating per face the transformation based on its first 3 vertices, and store this transformation averaged in the face's vertices. The solution can also only work on entire faces, because the full deform can only be retrieved using 3 vertices. (using 2 vertices will miss edge- aligned rotation, using 1 vertex can only retrieve translation). By deriving the deformations per face, small errors will still happen, especially on very low-poly Meshes with extreme deformations. The only alternative I know now, is providing each vertex in a mesh with 2 extreme small tangent vectors, which get deformed using the existing code as well. That will mess up the existing deformation code too much though, this solution has the benefit it works with each deform we can up with later too. Last note about CrazySpace: it can only be used to tweak Meshes. Do not even try to add vertices, extrude, or duplicate. Probably we should disable this... but preventing user errors isn't always power-user-friendly, eh. :)
