Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later. Cycles uses code from some great open source projects, many thanks them: * BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs": http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/ * Open Shading Language for a large part of the shading system: http://code.google.com/p/openshadinglanguage/ * Blender for procedural textures and a few other nodes. * Approximate Catmull Clark subdivision from NVidia Mesh tools: http://code.google.com/p/nvidia-mesh-tools/ * Sobol direction vectors from: http://web.maths.unsw.edu.au/~fkuo/sobol/ * Film response functions from: http://www.cs.columbia.edu/CAVE/software/softlib/dorf.php

#include <vector>
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.

Cycles: Implement guarded allocator for STL classes The commit implements a guarded allocator which can be used by STL classes such as vectors, maps and so on. This allocator will keep track of current and peak memory usage which then can be queried. New code for allocator is only active when building Cycles with debug flag (WITH_CYCLES_DEBUG) and doesn't distort regular builds too much. Additionally now we're using own subclass of std::vector which allows us to implement shrink_to_fit() method which would ensure capacity of the vector is as big as it should be (without this making vector smaller will still use all previous memory allocated).
2015-02-14 18:03:39 +05:00
*
Cycles: Always use guarded allocator of vectors We don't have vectors re-allocation happening multiple times from inside a loop anymore, so we can safely switch to a memory guarded allocator for vectors and keep track on the memory usage at various stages of rendering. Additionally, when building from inside Blender repository, Cycles will use Blender's guarded allocator, so actual memory usage will be displayed in the Space Info header. There are couple of tricky aspects of the patch: - TaskScheduler::exit() now explicitly frees memory used by `threads`. This is needed because `threads` is a static member which destructor isn't getting called on Blender's exit which caused memory leak print to happen. This shouldn't give any measurable speed issues, reallocation of that vector is only one of fewzillion other allocations happening during synchronization. - Use regular guarded malloc (not aligned one). No idea why it was made to be aligned in the first place. Perhaps some corner case tests or so. Vector was never expected to be aligned anyway. Let's see if we'll have actual bugs with this.
