Cycles: Add a cmake config to easily compile Cycles Standalone. On Linux/Mac OS X, simply type "make cycles" inside the Blender source directory, to get a standalone build of the engine. Reviewed by: Brecht Differential Revision: https://developer.blender.org/D228

Arrempt to fix Cycles compilation with Clang Issue is caused by missing sse flags for Clang compilers, this flags only was set for GNU C compilers. Added if branch for Clang now, which contains the same flags apart from -mfpmath=sse, This is because Clang was claiming it's unused argument. Probably OSX would need some further checks since it's also using Clang. I've got no idea why it could have worked for OSX before..

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

Cycles: Add support for debug passes Currently only summed number of traversal steps and intersections used by the camera ray intersection pass is implemented, but in the future we will support more debug passes which would help checking what things makes the scene slow. Example of such extra passes could be number of bounces, time spent on the shader tree evaluation and so. Implementation from the Cycles side is pretty much straightforward, could only mention here that it's a build-time option disabled by default. From the blender side it's implemented as a PASS_DEBUG with several subtypes possible. This way we don't need to create an extra DNA pass type for each of the debug passes, saving us a bits.

# Logging capabilities using GLog library.
Cycles: Add support of Glog logging This commit makes it possible to use Glog library for the debug logging. For now only possible when using CMake and in order to use the logging the WITH_CYCLES_LOGGING configuration variable is to be enabled. When this option is not enabled or when using Scons there's no difference in Cycles behavior at all, when using logging and no output to the console impact is gonna to be minimal. This is done in order to make it possible to have debug logging persistent in code (without need to add it when troubleshooting some bug and removing it afterwards). For now actual logging is not placed yet, only all the functions needed for the logging are written and so.

Cycles: Add support of Glog logging This commit makes it possible to use Glog library for the debug logging. For now only possible when using CMake and in order to use the logging the WITH_CYCLES_LOGGING configuration variable is to be enabled. When this option is not enabled or when using Scons there's no difference in Cycles behavior at all, when using logging and no output to the console impact is gonna to be minimal. This is done in order to make it possible to have debug logging persistent in code (without need to add it when troubleshooting some bug and removing it afterwards). For now actual logging is not placed yet, only all the functions needed for the logging are written and so.

Cycles: Add support for debug passes Currently only summed number of traversal steps and intersections used by the camera ray intersection pass is implemented, but in the future we will support more debug passes which would help checking what things makes the scene slow. Example of such extra passes could be number of bounces, time spent on the shader tree evaluation and so. Implementation from the Cycles side is pretty much straightforward, could only mention here that it's a build-time option disabled by default. From the blender side it's implemented as a PASS_DEBUG with several subtypes possible. This way we don't need to create an extra DNA pass type for each of the debug passes, saving us a bits.

Cycles: Fix compilation error when OIIO is compiled with external PugiXML parser Basic idea is to check whether OIIO is compiled with embedded PugiXML parser and if so use PugiXML from OIIO, otherwise find a standalone PugiXML library.

Cycles: Post-reintegration tweaks to ensure things do compile This commit contains all the tweaks which were missing in initial patch re-integration from the standalone Cycles repository. This commit also contains an utility cmake macro to help linking targets with different libraries for release/debug builds, the name currently is target_link_libraries_decoupled it gets a target and list of libraries and makes sure debug builds are using libraries with "_d" suffix. After all this changes it'll hopefully be easier to interchange patches between blender and standalone repositories, because they're now quite identical.
