Fix for crashes due to links without fromnode pointers. This can happen with "unfinished" links created during the modal linking operator or when creating links from group tree inputs. In addition don't store unfinished links in the nodetree->links list any more. This makes code a bit safer because all links in that list can be considered valid now. The temporary bNodeLinkDrag structs used by the modal linking operator are now also stored in a list in SpaceNode, so these links can be drawn too (this separation also allows different display of temporary links, e.g. currently they are drawn on top of all nodes).

struct bNodeLinkDrag *next, *prev;
A generalization of the modal node linking operator (for dragging from socket to socket). This operator still had some built-in assumptions about the connectivity of input/output sockets (1-to-n in all current node systems). For future node systems (e.g. flow-based particles) and for general customizable nodes the operator is now fully symmetric and supports all kinds of connectivity limits (1:1, 1:n, m:1, m:n). The operator data can also store a list of node links as opposed to a single link now, so that multiple links can be redirected at once. Holding the CTRL key when clicking a socket, all links from/to that socket are detached and can be moved to a different socket. This is useful for quickly appending a node without moving every individual link.

Reroute nodes, by Jeroen Bakker (patch #28443). By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when deleting a node, or to control the path of long connections for layout cleanup.

Key Configuration Keymaps are now saveable and configurable from the user preferences, note that editing one item in a keymap means the whole keymap is now defined by the user and will not be updated by Blender, an option for syncing might be added later. The outliner interface is still there, but I will probably remove it. There's actually 3 levels now: * Default builtin key configuration. * Key configuration loaded from .py file, for configs like Blender 2.4x or other 3D applications. * Keymaps edited by the user and saved in .B.blend. These can be saved to .py files as well to make creating distributable configurations easier. Also, user preferences sections were reorganized a bit, now there is: Interface, Editing, Input, Files and System. Implementation notes: * wmKeyConfig was added which represents a key configuration containing keymaps. * wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap. * Modal maps are not wrapped yet. * User preferences DNA file reading did not support newdataadr() yet, added this now for reading keymaps. * Key configuration related settings are now RNA wrapped. * is_property_set and is_property_hidden python methods were added.

Fix for toggle buttons in node headers. The buttons for "hiding" (collapsing) a node, hiding unlinked sockets, additional options, the preview and for opening a node group were all using a custom mouse test function, which was broken. They now use actual buttons instead of just displaying icons. Before executing the respective operators the button's node has to be selected and activated, so the buttons use an intermediate handle function, which selects the node and then calls the operator.

void node_socket_select(struct bNode *node, struct bNodeSocket *sock);
void node_socket_deselect(struct bNode *node, struct bNodeSocket *sock, int deselect_node);
Node socket selection feature reimplemented from 2.49. Sockets can be selected as a sub-selection of nodes and are then preferred by the auto-connect operator. This makes it easier to create precise links over long distances as an alternative to the click & hold operator. Socket selection is indicated by a simple white highlight circle. Multiple inputs can be selected by holding SHIFTKEY (just like regular node select). Only one output socket can be selected at a time for each node, but several outputs in different nodes are allowed. The auto-connect operator will prefer selected sockets on nodes for creating links. If either the output or input side have no selected sockets it will fall back to the previous behavior of chosing 'best' sockets first (colors, then vectors, then values). This could be improved in the future, but is out of scope here.

- use clear, set, add, enable, disable and toggle as a prefix in operator names - use select as a suffix eg UV_OT_loop_select -> UV_OT_select_loop - Each select all operator was using slightly different wording... select_all, deselect_all, de_select_all, select_de_select_all -> select_all_toggle - selection -> select - POSE_OT_select_connected -> POSE_OT_select_linked to match other operators - NODE_OT_delete_selection -> NODE_OT_delete since its not used in other operators - ANIM_OT_previewrange_define -> ANIM_OT_previewrange_set to match other operators - NODE_OT_fit_all -> NODE_OT_view_all to match other operators - View2D_OT_* -> VIEW2D_OT_* to match VIEW3D - View2D_OT_view_downscroll -> VIEW2D_OT_scroll_down more logical - removed MARKER_OT_mouseselect_extend and made extend a boolean property of MARKER_OT_mouseselect - MARKER_OT_mouseselect -> MARKER_OT_select - GROUP_OT_group_remove -> GROUP_OT_objects_remove more logical since its removing objects from groups - MESH_OT_removedoublesflag -> MESH_OT_remove_doubles - redundant words MESH_OT_split_mesh -> MESH_OT_split, OBJECT_OT_object_delete -> OBJECT_OT_delete renamed selection operator properties extend_select -> extend column_select -> column select_children_only -> children_only ... Since these are all in the context of selection operators there is no need for the extra 'select' in the property name.

several cosmetic changes to the node-editor + changed lines connecting nodes: they now use a linewidth of 1.5px for the light foreground and 4px for the dark background. this should fix node-lines not being visible on almost black or all white backdrops. + muted nodes now also show a red tinted header if they are hidden (collapsed) + both active and selected nodes show a (now properly antialiased) highlighting frame + fixed a small error in dropshadow code resulting in a gap at borders + fixed a tiny error for the collapsing indicators (triangles) - they were not symmetrical. Ton will add proper theme colors for the node-editor in the coming days.

Note it now nicely intersects the real curved noodles with a line you draw! - To make above work, replaced ogl curve draw with own bezier code. - Added new WM standard operator callback for lines-gesture, the Lasso gesture now draws a closed line. - Both callbacks have optional property 'cursor' to make it give modal info. For future also linestyle or color can be defined. - Changed 'pin' icon in Image header to something that looks less scary... but there's no pin icon yet?

Check this file for fun: http://www.blender.org/bf/composite_image.blend (any compo node could get preview!) - had to ensure the composite data gets fully copied before it executes thread, so editing is not frustrated. - put back node buttons (missing init) - added WM_jobs api call to check for running job, illustrated with red light icon in 'use nodes' button. - added another callback to WM_jobs, to initialize. use this init to ensure you only do it when job really starts. - added an extra notifier option for WM_jobs, to signal finished job (like redraw image view) - fixed file read error, it copied the screen it read, instead of using it. - commented out annoying prints for missing ops in imagewin

Reverted r43219 "Improved auto-hiding of unused sockets for collapsed nodes." This feature did have a number of flaws and caused some controversy, so removal is the better option. Hiding nodes without prior connections would just hide all the sockets, leaving an unusable node. Better way is to use the ctrl+h shortcut to explicitly hide unused sockets when necessary.

Todo/feature request When using masks or other simple 3D elements in composites, doing a layer re-rendering on a node is a bit clumsy all the time. This commit does two things to help: - new hotkey "Z" in node editor automatically finds render layer that changed and re-renders it + composites - option "Auto Render" does same, but then after every transform edit in 3D window The latter is experimental; real & proper system for this requires full threaded render support (like previews). But it works! Demo file: http://download.blender.org/demo/test/auto_composite.blend Important fix: After any render, all the render layers were tagged "changed", which caused any edit to first totally recomposte everthing. Now it only composites changes. Implementation notes - DAG scene flush now sets 'changed' flags in render layer nodes - Added notifier for 'transform finished' to trigger the update, this is temporarily.

int node_render_changed_exec(bContext *, wmOperator *);
Node socket selection feature reimplemented from 2.49. Sockets can be selected as a sub-selection of nodes and are then preferred by the auto-connect operator. This makes it easier to create precise links over long distances as an alternative to the click & hold operator. Socket selection is indicated by a simple white highlight circle. Multiple inputs can be selected by holding SHIFTKEY (just like regular node select). Only one output socket can be selected at a time for each node, but several outputs in different nodes are allowed. The auto-connect operator will prefer selected sockets on nodes for creating links. If either the output or input side have no selected sockets it will fall back to the previous behavior of chosing 'best' sockets first (colors, then vectors, then values). This could be improved in the future, but is out of scope here.

- use clear, set, add, enable, disable and toggle as a prefix in operator names - use select as a suffix eg UV_OT_loop_select -> UV_OT_select_loop - Each select all operator was using slightly different wording... select_all, deselect_all, de_select_all, select_de_select_all -> select_all_toggle - selection -> select - POSE_OT_select_connected -> POSE_OT_select_linked to match other operators - NODE_OT_delete_selection -> NODE_OT_delete since its not used in other operators - ANIM_OT_previewrange_define -> ANIM_OT_previewrange_set to match other operators - NODE_OT_fit_all -> NODE_OT_view_all to match other operators - View2D_OT_* -> VIEW2D_OT_* to match VIEW3D - View2D_OT_view_downscroll -> VIEW2D_OT_scroll_down more logical - removed MARKER_OT_mouseselect_extend and made extend a boolean property of MARKER_OT_mouseselect - MARKER_OT_mouseselect -> MARKER_OT_select - GROUP_OT_group_remove -> GROUP_OT_objects_remove more logical since its removing objects from groups - MESH_OT_removedoublesflag -> MESH_OT_remove_doubles - redundant words MESH_OT_split_mesh -> MESH_OT_split, OBJECT_OT_object_delete -> OBJECT_OT_delete renamed selection operator properties extend_select -> extend column_select -> column select_children_only -> children_only ... Since these are all in the context of selection operators there is no need for the extra 'select' in the property name.

void NODE_OT_delete(struct wmOperatorType *ot);
Add delete with reconnect feature. this will reconnect nodes as if the deleted node is muted. Operation is added to the space_node node menu and to the keymap as CTRL-X to test this just add some nodes to the space_node select one or multiple nodes and press CTRL-X It should reconnect the nodes as they were muted limitations: 1. it performs a delete and reconnect per node. It does not evaluate all selected nodes as one whole 2. mute only supports Value, Vector and Color data types, so does this feature 3. not usable for nodes where input and output does not match (like colorToBW) Where reconnect could not be preformed the links will be removed from the model. Undo works with this delete with reconnect.

For future also linestyle or color can be defined. - Changed 'pin' icon in Image header to something that looks less scary... but there's no pin icon yet?

void NODE_OT_links_cut(struct wmOperatorType *ot);
Implements a new operator for detaching nodes. In the process i overhauled the node muting system as well. There are a number of features that use a kind of "internal linking" in nodes: 1. muting 2. delete + reconnect (restore link to/from node after delete) 3. the new detach operator (same as 2, but don't delete the node) The desired behavior in all cases is the same: find a sensible mapping of inputs-to-outputs of a node. In the case of muting these links are displayed in red on the node itself. For the other operators they are used to relink connections, such that one gets the best possible ongoing link between previous up- and downstream nodes. Muting previously used a complicated callback system to ensure consistent behavior in the editor as well as execution in compositor, shader cpu/gpu and texture nodes. This has been greatly simplified by moving the muting step into the node tree localization functions. Any muted node is now bypassed using the generalized nodeInternalRelink function and then removed from the local tree. This way the internal execution system doesn't have to deal with muted nodes at all, as if they are non-existent. The same function is also used by the delete_reconnect and the new links_detach operators (which work directly in the editor node tree). Detaching nodes is currently keymapped as a translation variant (macro operator): pressing ALTKEY + moving node first detaches and then continues with regular transform operator. The default key is ALT+DKEY though, instead ALT+GKEY, since the latter is already used for the ungroup operator.

Reroute nodes, by Jeroen Bakker (patch #28443). By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when deleting a node, or to control the path of long connections for layout cleanup.

Fix for toggle buttons in node headers. The buttons for "hiding" (collapsing) a node, hiding unlinked sockets, additional options, the preview and for opening a node group were all using a custom mouse test function, which was broken. They now use actual buttons instead of just displaying icons. Before executing the respective operators the button's node has to be selected and activated, so the buttons use an intermediate handle function, which selects the node and then calls the operator.

A number of improvements for the file output node(s). 1) Old CMP_NODE_OUTPUT_FILE and CMP_NODE_OUTPUT_MULTI_FILE have been merged, only CMP_NODE_OUTPUT_FILE remains. All functions renamed accordingly. 2) do_versions code for converting single-file output nodes into multi-file output nodes. If a Z buffer input is used, the node is made into a multilayer exr with two inputs. (see below). Also re-identifies multi-file output nodes with the CMP_NODE_OUTPUT_FILE type. 3) "Global" format is stored in node now. By default this overrides any per-socket settings. 4) Multilayer EXR output implemented. When M.EXR format is selected for node format, all socket format details are ignored. Socket names are used for layer names. 5) Input buffer types are used as-is when possible, i.e. stored as B/W, RGB or RGBA. In regular file output the format dictates the number of actual channels, so the CompBuf is typechecked to the right type first. For multilayer EXR the number of channels is more flexible, so an input buffer will store only the channels it actually uses. 6) The editor socket type is updated from linked sockets as an indicator of the actual data written to files. This may not be totally accurate for regular file output though, due to restrictions of format setting.

void NODE_OT_output_file_add_socket(struct wmOperatorType *ot);
void NODE_OT_output_file_remove_active_socket(struct wmOperatorType *ot);
A number of changes to node RNA and the file output node, to simplify socket types and make node code more robust for future nodes with extra socket data. * Removed the struct_type identifier from sockets completely. Any specialization of socket types can be done by using separate collections in RNA and customized socket draw callbacks in node type. Sockets themselves are pure data inputs/outputs now. Possibly the sock->storage data could also be removed, but this will change anyway with id properties in custom nodes. * Replaced the direct socket button draw calls by extra callbacks in node types. This allows nodes to draw sockets in specialized ways without referring to the additional struct_type identifier. Default is simply drawing the socket default_value button, only file output node overrides this atm. * File output node slots now use a separate file sub-path in their storage data, instead of using the socket name. That way the path is an actual PROP_FILEPATH property and it works better with the UI list template (name property is local to the data struct). * Node draw contexts for options on the node itself and detail buttons in the sidebar now have an extra context pointer "node" (uiLayoutSetContextPointer). This can be used to bind operator buttons to a specific node, instead of having to rely on the active/selected node(s) or making weak links via node name. Compare to modifiers and logic bricks, they use the same feature. * Added another operator for reordering custom input slots in the file output node.
2012-05-02 07:18:51 +00:00
void NODE_OT_output_file_move_active_socket(struct wmOperatorType *ot);
Adds a new node type for saving multiple image files from a single node. Unlike the existing file output node this node has an arbitrary number of possible input slots. It has a base path string that can be set to a general base folder. Every input socket then uses its name as an extension of the base path for file organization. This can include further subfolders on top of the base path. Example: Base path: '/home/user/myproject' Input 1: 'Compo' Input 2: 'Diffuse/' Input 3: 'details/Normals' would create output files in /home/user/myproject: Compo0001.png, Compo0002.png, ... in /home/user/myproject/Diffuse: 0001.png, 0002.png, ... (no filename base given) in /home/user/myproject/details: Normals0001.png, Normals0002.png, ... Most settings for the node can be found in the sidebar (NKEY). New input sockets can be added with the "Add Input" button. There is a list of input sockets and below that the details for each socket can be changed, including the sub-path and filename. Sockets can be removed here as well. By default each socket uses the render settings file output format, but each can use its own format if necessary. To my knowledge this is the first node making use of such dynamic sockets in trunk. So this is also a design test, other nodes might use this in the future. Adding operator buttons on top of a node is a bit unwieldy atm, because all node operators generally work on selected and/or active node(s). The operator button would therefore either have to make sure the node is activated before the operator is called (block callback maybe?) OR it has to store the node name (risky, weak reference). For now it is only used in the sidebar, where only the active node's buttons are displayed. Also adds a new struct_type value to bNodeSocket, in order to distinguish different socket types with the same data type (file inputs are SOCK_RGBA color sockets). Would be nicer to use data type only for actual data evaluation, but used in too many places, this works ok for now.
