Cycles: fully decouple triangle and curve primitive storage from BVH2 Previously the storage here was optimized to avoid indirections in BVH2 traversal. This helps improve performance a bit, but makes performance and memory usage of Embree and OptiX BVHs a bit worse also. It also adds code complexity in other parts of the code. Now decouple triangle and curve primitive storage from BVH2. * Reduced peak memory usage on all devices * Bit better performance for OptiX and Embree * Bit worse performance for CUDA * Simplified code: ** Intersection.prim/object now matches ShaderData.prim/object ** No more offset manipulation for mesh displacement before a BVH is built ** Remove primitive packing code and flags for Embree and OptiX ** Curve segments are now stored in a KernelCurve struct * Also happens to fix a bug in baking with incorrect prim/object Fixes T91968, T91770, T91902 Differential Revision: https://developer.blender.org/D12766

KERNEL_TEX(float, __object_volume_step)
Cycles: MetalRT support (kernel side) This patch adds MetalRT support to Cycles kernel code. It is mostly additive in nature or confined to Metal-specific code, however there are a few areas where this interacts with other code: - MetalRT closely follows the Optix implementation, and in some cases (notably handling of transforms) it makes sense to extend Optix special-casing to MetalRT. For these generalisations we now have `__KERNEL_GPU_RAYTRACING__` instead of `__KERNEL_OPTIX__`. - MetalRT doesn't support primitive offsetting (as with `primitiveIndexOffset` in Optix), so we define and populate a new kernel texture, `__object_prim_offset`, containing per-object primitive / curve-segment offsets. This is referenced and applied in MetalRT intersection handlers. - Two new BVH layout enum values have been added: `BVH_LAYOUT_METAL` and `BVH_LAYOUT_MULTI_METAL_EMBREE` for XPU mode). Some host-side enum case handling has been updated where it is trivial to do so. Ref T92212 Reviewed By: brecht Maniphest Tasks: T92212 Differential Revision: https://developer.blender.org/D13353

Cycles: pointcloud rendering This add support for rendering of the point cloud object in Blender, as a native geometry type in Cycles that is more memory and time efficient than instancing sphere meshes. This can be useful for rendering sand, water splashes, particles, motion graphics, etc. Points are currently always rendered as spheres, with backface culling. More shapes are likely to be added later, but this is the most important one and can be customized with shaders. For CPU rendering the Embree primitive is used, for GPU there is our own intersection code. Motion blur is suppored. Volumes inside points are not currently supported. Implemented with help from: * Kévin Dietrich: Alembic procedural integration * Patrick Mourse: OptiX integration * Josh Whelchel: update for cycles-x changes Ref T92573 Differential Revision: https://developer.blender.org/D9887

Particle Info node for Cycles. This can be used to access particle information in material shaders for dupli objects. For now only the particle Age and individual Lifetime (in frames) are supported, more attributes can be added when needed. The particle data is stored in a separate texture if any of the dupli objects uses particle info nodes in shaders. To map dupli objects onto particles the store an additional particle_index value, which is different from the simple dupli object index (only visible particles, also works for particle dupli groups mode).

Cycles: Add Support for IES files as textures for light strength This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources. The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp. Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried. Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file. The user interface of the node is similar to the script node, the user can either select an internal Text or load a file. Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot. The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light, rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.
