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)

* Uniform buffers API. Used to handle many uniforms update at once.
* Make sure that the data structure is compatible with what the implementation expect.
* (see "7.6.2.2 Standard Uniform Block Layout" from the OpenGL spec for more info about std140
* layout)
* Rule of thumb: Padding to 16bytes, don't use vec3, don't use arrays of anything that is not vec4
* aligned .

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

#define GPU_UBO_BLOCK_NAME "nodeTree"
Materials: add custom object properties as uniform attributes. This patch allows the user to type a property name into the Attribute node, which will then output the value of the property for each individual object, allowing to e.g. customize shaders by object without duplicating the shader. In order to make supporting this easier for Eevee, it is necessary to explicitly choose whether the attribute is varying or uniform via a dropdown option of the Attribute node. The dropdown also allows choosing whether instancing should be taken into account. The Cycles design treats all attributes as one common namespace, so the Blender interface converts the enum to a name prefix that can't be entered using keyboard. In Eevee, the attributes are provided to the shader via a UBO indexed with resource_id, similar to the existing Object Info data. Unlike it, however, it is necessary to maintain a separate buffer for every requested combination of attributes. This is done using a hash table with the attribute set as the key, as it is expected that technically different but similar materials may use the same set of attributes. In addition, in order to minimize wasted memory, a sparse UBO pool is implemented, so that chunks that don't contain any data don't have to be allocated. The back-end Cycles code is already refactored and committed by Brecht. Differential Revision: https://developer.blender.org/D2057
