2021-02-16Cleanup: Compile node_draw.c with C++Hans Goudey
This will allow using C++ data structures to draw node error messages. This required removing a forward declared enum for grease pencil undo. Compiles with clang tidy.

2021-02-11UI: Multi-input node socket spacing and interactionFabian Schempp
This commit makes links connected to multi-input sockets spread verticaly along the socket. Sockets grow if more links are connected and the node layout updates accordingly. Links are sorted by their incoming angle to avoid crossing links. Also, link picking is updated to work with spread links and bezier links. Currently the multi-input sockets are used in the join geometry node. The mutli-input sockets look like a vertical rounded rectangle. Currently they do not support the other custom socket shapes.

2021-01-25Cleanup: pass 'rctf' rectangle to 2D box drawing functionsCampbell Barton
Passing 4x arguments for the rectangle, mixed in with round-box radius & color wasn't very readable. Instead, pass a `rctf` as the first argument to UI box drawing functions.
2021-01-20Cleanup: Store runtime space node variables in a separate structHans Goudey
This commit moves runtime-only variables from the `SpaceNode` DNA struct to a private struct in `node_intern.h`. Before, it was hard to tell which data needed to be saved in files, this should make it more clear. Node that the `edittree` field is basically a runtime variable, since it's set from the `treepath` list on read, but moving it would require some more invasive changes that I don't think are worth it right now. Also, not all of the moved variables were explicitly cleared on read-- `aspect` is set at the start of a redraw, `cursor` is set in a region callback, and `recalc` was used as an update flag.

2021-01-15Cleanup: Add const in various places in node codeHans Goudey
Also includes some various other minor cleanups, like using bool instead of int in a couple places.

2020-12-02UI: Add new node colors for geometry nodesHans Goudey
During the development of the new nodes in the `geometry-nodes` branch the color of the new nodes wasn't considered, so all of the nodes ended up red, the color for "input" nodes. This patch introduces two new colors, one for "Geometry" and one for "Attributes". There are only two attribute nodes currently, but the next sprint will add two more, attribute mix, and sample from texture. The attribute nodes are conceptually different enough from the nodes that modify the geometry that they deserve their own color. Differential Revision: https://developer.blender.org/D9682
2020-12-02Geometry Nodes: initial scattering and geometry nodesJacques Lucke
This is the initial merge from the geometry-nodes branch. Nodes: * Attribute Math * Boolean * Edge Split * Float Compare * Object Info * Point Distribute * Point Instance * Random Attribute * Random Float * Subdivision Surface * Transform * Triangulate It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier. Notes on the Generic attribute access API The API adds an indirection for attribute access. That has the following benefits: * Most code does not have to care about how an attribute is stored internally. This is mainly necessary, because we have to deal with "legacy" attributes such as vertex weights and attributes that are embedded into other structs such as vertex positions. * When reading from an attribute, we generally don't care what domain the attribute is stored on. So we want to abstract away the interpolation that that adapts attributes from one domain to another domain (this is not actually implemented yet). Other possible improvements for later iterations include: * Actually implement interpolation between domains. * Don't use inheritance for the different attribute types. A single class for read access and one for write access might be enough, because we know all the ways in which attributes are stored internally. We don't want more different internal structures in the future. On the contrary, ideally we can consolidate the different storage formats in the future to reduce the need for this indirection. * Remove the need for heap allocations when creating attribute accessors. It includes commits from: * Dalai Felinto * Hans Goudey * Jacques Lucke * Léo Depoix
2020-11-30Cleanup: Reduce variable scope in node drawing codeHans Goudey
Also use LISTBASE_FOREACH in a few places and generally clean up the code for the two sidebar panels "Sockets" and "Interface".
2020-11-19Fix lost node links when linked node group datablock is temporarily missingBrecht Van Lommel
Don't refresh the list of sockets, so that when the .blend file is restored the links remain valid. Also display such nodes in red to indicate an error, same as when the node type info is missing.

2020-09-16UI: Add grid-related theme optionsRed Mser
This commit makes grid theming more consistent and capable by adding some new theme colors related to grid rendering. - Add grid theme color for node editor. `UI_view2d_multi_grid_draw` is called with TH_GRID instead of a shaded `TH_BACK`. Also color-blend `TH_NODE_GROUP`. - Make the movie clip editor's clip preview grid respect grid theme color (`ED_region_grid_draw` uses color-blended `TH_GRID`). - Add versioning code to allow fixing existing themes (the resulting themes should visually look the same as before) These changes did cause some inconsistencies in the movie clip editor, even after adjusting the themes accordingly: 1. The alpha slider of the grid color affects the background and not the grid lines themselves. 2. The grids used by graph and dopesheet mode could already be themed in the past. Now that the clip preview's grid can also be themed, two different modes share the same theme color. Differential Revision: https://developer.blender.org/D8699

2020-08-23Cleanup: GPU: Use explicit clear value in GPU_clear* commandsClément Foucault
This replace `GPU_clear()` by `GPU_clear_color()` and `GPU_clear_depth()`. Since we always set the clear value before clearing, it is unecessary to track the clear color state. Moreover, it makes it clearer what we clear the framebuffer to.

2020-06-22Refactoring: View2DScrollers memory allocationJeroen Bakker
View2DScrollers used the memory manager to allocate memory. This isn't a problem but in a upcoming change the scrollers will be drawn more often than it used to (See {D8066}). To limit the number of allocations and frees this patch will use the stack for allocation. Reviewed By: Campbell Barton Differential Revision: https://developer.blender.org/D8076

2020-04-16UI: Draw real node sockets for node input buttonsJulian Eisel
For buttons representing node inputs (e.g. in the material properties) rather than drawing some generic socket icon, the actual sockets are drawn now. That includes color, shape and the selection outline. This should make it easier to understand what these buttons relate to. Screenshots: {F8469252}, {F8469248} (The left alignment will be done in a follow-up commit.)
