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)
