2020-11-10	Fix NanoVDB compile errors with recent NanoVDB versions	Patrick Mours
	There were some changes to the NanoVDB API that broke the way Cycles was previously using it. With these changes it compiles successfully again and also still compiles with the NanoVDB revision that is currently part of the Blender dependencies. Ref T81454.
2020-11-09	Cycles: Fix tricubic sampling with NanoVDB	Patrick Mours
	Volumes using tricubic sampling were producing different results with NanoVDB compared to dense textures. This fixes that by using the same tricubic sampling algorithm in both cases. It also fixes some remaining offset issues and some minor things that broke OpenCL kernel compilation on NVIDIA. Reviewed By: brecht Differential Revision: https://developer.blender.org/D9491
2020-11-04	Fix Cycles volume render differences with NanoVDB when using linear sampling	Patrick Mours
	The NanoVDB sampling implementation behaves different from dense texture sampling, so this adds a small offset to the voxel indices to correct for that. Also removes the need to modify the sampling coordinates by moving all the necessary transformations into the image transform. See also T81454.
2020-10-05	Cycles: Add NanoVDB support for rendering volumes	Patrick Mours
	NanoVDB is a platform-independent sparse volume data structure that makes it possible to use OpenVDB volumes on the GPU. This patch uses it for volume rendering in Cycles, replacing the previous usage of dense 3D textures. Since it has a big impact on memory usage and performance and changes the OpenVDB branch used for the rest of Blender as well, this is not enabled by default yet, which will happen only after 2.82 was branched off. To enable it, build both dependencies and Blender itself with the "WITH_NANOVDB" CMake option. Reviewed By: brecht Differential Revision: https://developer.blender.org/D8794
2020-03-18	Cycles: support for different 3D transform per volume grid	Brecht Van Lommel
	This is not yet fully supported by automatic volume bounds but works fine in most cases that will have mostly matching bounds. Ref T73201
2020-03-11	Cleanup: stop encoding image data type in slot index	Brecht Van Lommel
	This is legacy code from when we had a fixed number of textures.
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
2018-07-06	Cleanup: strip trailing space for cycles	Campbell Barton

2018-07-05	Cycles: Adding native support for UINT16 textures.	Stefan Werner
	Textures in 16 bit integer format are sometimes used for displacement, bump and normal maps and can be exported by tools like Substance Painter. Without this patch, Cycles would promote those textures to single precision floating point, causing them to take up twice as much memory as needed.

2018-02-18	Cycles: Remove Fermi texture code.	Thomas Dinges
	This should be the last Fermi removal commit, unless I missed something. It's been a pleasure Fermi!
2017-10-15	Fix OpenCL performance regression after cubic interpolation.	Brecht Van Lommel
	Reorganize code to reduce register pressure.
2017-10-10	Cycles: Fix compilation of sm_20 and sm_21 kernels	Sergey Sharybin
	Was broken since the bicubic commit for GPU support.
2017-10-07	Cycles: CUDA bicubic and tricubic texture interpolation support.	Brecht Van Lommel
	While cubic interpolation is quite expensive on the CPU compared to linear interpolation, the difference on the GPU is quite small.
2017-10-07	Code refactor: make texture code more consistent between devices.	Brecht Van Lommel
	* Use common TextureInfo struct for all devices, except CUDA fermi. * Move image sampling code to kernels//kernel__image.h files. * Use arrays for data textures on Fermi too, so device_vector<Struct> works.
