Cycles: Point density texture support This commit implements point density texture for Cycles shading nodes. It's done via creating voxel texture at shader compilation time, Not totally memory efficient, but avoids adding sampling code to kernel (which keeps render time as low as possible), In the future this will be compensated by using OpenVDB for more efficient storage of sparse volume data. Sampling of the voxel texture is happening at blender side and the same code is used as for Blender Internal's renderer. This texture is controlled by only object, particle system and radius. Linear falloff is used and there's no turbulence. This is because falloff is expected to happen using Curve Mapping node. Turbulence will be done as a distortion on the input coordinate. It's already possible to fake it using nose textures and in the future we can add more proper turbulence distortion node, which then could also be used for 2D texture mapping. Particle color support is done by Lukas, thanks! 2015-07-18 22:36:09 +02:00

Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file. 2021-10-24 14:19:19 +02:00			`#include "blender/sync.h"`
Cleanup: `make format` after SortedIncludes change 2020-03-19 09:33:03 +01:00			`#include <stdlib.h>`

Point cache: Pass EvaluationContext for all the related functions Now the only missing bit seems to be in Cycles to pass depsgraph to builtin_image_float_pixels(). Ideally we could get evaluation context instead of using depsgraph + settings. But for the other rna EvaluationContext functions this is how we are doing.

Cycles: Pass Blender's C++ RNA structures by reference This way we avoid passing structures which could be up to few hundred bytes by value to the utility functions. Ideally we'll also have to add `const` qualifier in majority of the calls, but C++ RNA does not allow us to do that because it does not know if some function modifies contents or not. 2016-01-30 14:18:29 +01:00			`BL::ShaderNodeTexPointDensity &b_point_density_node,`
