Clay-Engine (merge clay-engine) Initial work by Clément Foucault with contributions from Dalai Felinto (mainly per-collection engine settings logic, and depsgraph iterator placeholder). This makes Blender require OpenGL 3.3. Which means Intel graphic card and OSX will break. Disable CLAY_ENGINE in CMake in those cases. 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)

#ifndef __GPU_UNIFORMBUFFER_H__
#define __GPU_UNIFORMBUFFER_H__
Implement Uniformbuffer objects for nodetree parameters For users that means you can tweak shaders in the nodetree and things are way faster. This is a huge improvement, particularly in systems that have no shader cache. From the code perspective it means we are no longer re-compiling the shader every time a value is tweaked in the UI. We are using uniforms for those values. It would be slow to add that many uniforms for all the shaders. So instead we are using UBO (Uniform Buffer Objects). This fixes the main issue of T51467. However GWN_shaderinterface_create() still needs to be improvedi. When opening a .blend all shaders are compiled once, so optimizing it will bring a measurable impact. ======================================================================== NOTE: This breaks update of Cycles material upon nodetree nodes tweaking. It will be fixed separately by depsgraph, once tackling T51925 (Animated Eevee values slowdown). The idea is to make Depsgraph update more granular. The XXX TODO in rna_nodetree.c will be tackled at that time as well. ======================================================================== Reviewers: sergey, brecht, fclem Differential Revision: https://developer.blender.org/D2739
