This is a prototype render engine intended to help the design of real render engines. This is mainly an engine with enphasis in matcap and ambient occlusion. Implemented Features -------------------- * Clay Render Engine, following the new API, to be used as reference for future engines * A more complete Matcap customization with more options * Per-Collection render engine settings * New Ground Truth AO - not enabled Missing Features ---------------- * Finish object edit mode - Fix shaders to use new matrix - Fix artifacts when edge does off screen - Fix depth issue - Selection sillhouette - Mesh wires - Use mesh normals (for higher quality matcap) - Non-Mesh objects drawing - Widget drawing - Performance issues * Finish mesh edit mode - Derived-Mesh-less edit mode API (mesh_rende.c) * General edit mode - Per-collection edit mode settings * General engines - Per-collection engine settings (they are their, but they still need to be flushed by depsgraph, and used by the drawing code)

rename built-in point shaders, SMOOTH --> AA Updated shader names and code that uses them. All of these shaders produce round points that are anti-aliased and blended against the background. These were initially named SMOOTH because they replace glEnable(GL_POINT_SMOOTH). But SMOOTH in shader-land refers to vertex attribute interpolation (like glShadeModel(GL_SMOOTH)). Using SMOOTH to mean two things is confusing, so we now use AA to mean "the point is anti-aliased".

Edit UVs: Refactor drawing Edit UV in Image Editor NOTE: This commit only concern edit UVs and not the "shadow" mesh displayed when texture painting. This will be address in a future commit. We now cache the uv mesh in the mesh batch cache and only reupload data on changes. Update could be more granular (and a bit faster) but it's not our main concern ATM. This should fix problem caused by the IMM api used to draw large meshes. This makes performance skyrocket compared to previous implementation. There is still a big CPU bottleneck when not in sync selection mode but it is not related to the drawing function directly.

add GPU_SHADER_TEXT for font rendering With USE_GLSL enabled, GPU_basic_shader(TEXTURE|COLOR) always rendered black. New shader uses a solid color + alpha channel of texture (which in our case is a font glyph). See fragment shader for details. I prefer this approah -- multiple shaders that each do one thing well (and are easy to read/write/understand), instead of one shader that can do many things given the right options.

New Grease Pencil object for 2D animation This commit merge the full development done in greasepencil-object branch and include mainly the following features. - New grease pencil object. - New drawing engine. - New grease pencil modes Draw/Sculpt/Edit and Weight Paint. - New brushes for grease pencil. - New modifiers for grease pencil. - New shaders FX. - New material system (replace old palettes and colors). - Split of annotations (old grease pencil) and new grease pencil object. - UI adapted to blender 2.8. You can get more info here: https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/ https://code.blender.org/2018/07/grease-pencil-status-update/ This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible. Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.

GPU: refactor clipped drawing from DRW into GPU Needed to fix T61196, supporting clipped back-buffer in the 3D view which is done outside the draw module. It was also inconvenient having DRW_shader_* versions of GPU_shader_* API calls. - Clipping distances are now supported as a shader configuration for builtin shaders. - Add shader config argument when accessing builtin shaders. - Move GPU_shader_create_from_arrays() from DRW to GPU.

GPUShader: Implement workaround for gizmo drawing on sRGB framebuffer This solution involves adding a uniform to each fragment shader that is used by gizmo drawing and use the framebuffer state to set this uniform accordingly. This solution can also be carried to external shaders (addons). A single line of code would then be enough to fix the issue. The only trickery here is the dummy define: `#define srgb_to_framebuffer_space(a)` This is in order to avoid breaking other DRW shaders that use the same fragment shader code but do not need the tranformation.

GPUShaderCreateInfo for interface abstraction This is a first part of the Shader Create Info system could be. A shader create info provides a way to define shader structure, resources and interfaces. This makes for a quick way to provide backend agnostic binding informations while also making shader variations easy to declare. - Clear source input (only one file). Cleans up the GPU api since we can create a shader from one descriptor - Resources and interfaces are generated by the backend (much simpler than parsing). - Bindings are explicit from position in the array. - GPUShaderInterface becomes a trivial translation of enums and string copy. - No external dependency to third party lib. - Cleaner code, less fragmentation of resources in several libs. - Easy to modify / extend at runtime. - no parser involve, very easy to code. - Does not hold any data, can be static and kept on disc. - Could hold precompiled bytecode for static shaders. This also includes a new global dependency system. GLSL shaders can include other sources by using #pragma BLENDER_REQUIRE(...). This patch already migrated several builtin shaders. Other shaders should be migrated one at a time, and could be done inside master. There is a new compile directive `WITH_GPU_SHADER_BUILDER` this is an optional directive for linting shaders to increase turn around time. What is remaining: - pyGPU API {T94975} - Migration of other shaders. This could be a community effort.

Overlay Engine: Refactor & Cleanup This is the unification of all overlays into one overlay engine as described in T65347. I went over all the code making it more future proof with less hacks and removing old / not relevent parts. Goals / Acheivements: - Remove internal shader usage (only drw shaders) - Remove viewportSize and viewportSizeInv and put them in gloabl ubo - Fixed some drawing issues: Missing probe option and Missing Alt+B clipping of some shader - Remove old (legacy) shaders dependancy (not using view UBO). - Less shader variation (less compilation time at first load and less patching needed for vulkan) - removed some geom shaders when I could - Remove static e_data (except shaders storage where it is OK) - Clear the way to fix some anoying limitations (dithered transparency, background image compositing etc...) - Wireframe drawing now uses the same batching capabilities as workbench & eevee (indirect drawing). - Reduced complexity, removed ~3000 Lines of code in draw (also removed a lot of unused shader in GPU). - Post AA to avoid complexity and cost of MSAA. Remaining issues: - ~~Armature edits, overlay toggles, (... others?) are not refreshing viewport after AA is complete~~ - FXAA is not the best for wires, maybe investigate SMAA - Maybe do something more temporally stable for AA. - ~~Paint overlays are not working with AA.~~ - ~~infront objects are difficult to select.~~ - ~~the infront wires sometimes goes through they solid counterpart (missing clear maybe?) (toggle overlays on-off when using infront+wireframe overlay in solid shading)~~ Note: I made some decision to change slightly the appearance of some objects to simplify their drawing. Namely the empty arrows end (which is now hollow/wire) and distance points of the cameras/spots being done by lines. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D6296

GPU: refactor clipped drawing from DRW into GPU Needed to fix T61196, supporting clipped back-buffer in the 3D view which is done outside the draw module. It was also inconvenient having DRW_shader_* versions of GPU_shader_* API calls. - Clipping distances are now supported as a shader configuration for builtin shaders. - Add shader config argument when accessing builtin shaders. - Move GPU_shader_create_from_arrays() from DRW to GPU.

OpenGL: manage built-in shaders better As our library of built-in shaders grows, it's important to create, access, and discard them efficiently. Lookup via GPU_shader_get_builtin is now constant time instead of linear (# of built-in shaders). This is called very often with our new immediate mode. Creation and discard are unified. Adding a new shader requires fewer steps. 365 lines shorter :D

GPU: Move gpu_shader.c to C++ We split builtin shader support to its own file to avoid converting code (lack of designated initializer in C++) and to reduce file size.
