2020-10-23	Fix T81102: Cycles crashes in interactive 3D viewport rendering after Embree	Brecht Van Lommel
	Don't allocate a new buffer for refitting meshes, but update the existing one. It's not clear from the API docs if this is required, but it appears to solve the issue and should be more efficient.
2020-09-01	Cycles: Separate Embree device for each CPU Device.	Stefan Werner
	Before, Cycles was using a shared Embree device across all instances. This could result in crashes when viewport rendering and material preview were using Cycles simultaneously. Fixes issue T80042 Maniphest Tasks: T80042 Differential Revision: https://developer.blender.org/D8772
2020-06-22	Cycles: internal refactoring to make thick/ribbon curve separate primitives	Brecht Van Lommel
	Also removing the curve system manager which only stored a few curve intersection settings. These are all changes towards making shape and subdivision settings per-object instead of per-scene, but there is more work to do here.

2020-06-22	Cycles: remove support for rendering hair as triangle and lines	Brecht Van Lommel
	Triangles were very memory intensive. The only reason they were not removed yet is that they gave more accurate results, but there will be an accurate 3D curve primitive added for this. Line rendering was always poor quality since the ends do not match up. To keep CPU and GPU compatibility we just remove them entirely. They could be brought back if an Embree compatible implementation is added, but it's not clear to me that there is a use case for these that we'd consider important.

2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat
2019-01-09	Cycles: Make BVH wider prior to packing	Sergey Sharybin
	This allows to do more non-trivial tree modifications to make it more dense and more friendly for vectorization.
2018-11-09	Cycles: Cleanup, spacing after preprocessor	Sergey Sharybin
	It is supposed to be two spaces before comment stating which if else/endif statements corresponds to. Was mainly violated in the header guards.
2018-11-07	Cycles: Added Embree as BVH option for CPU renders.	Stefan Werner
	Note that this is turned off by default and must be enabled at build time with the CMake WITH_CYCLES_EMBREE flag. Embree must be built as a static library with ray masking turned on, the `make deps` scripts have been updated accordingly. There, Embree is off by default too and must be enabled with the WITH_EMBREE flag. Using Embree allows for much faster rendering of deformation motion blur while reducing the memory footprint. TODO: GPU implementation, deduplication of data, leveraging more of Embrees features (e.g. tessellation cache). Differential Revision: https://developer.blender.org/D3682
