Cycles / OSL: Fixes for API changes in OSL RendererServices: * Added two new required get_matrix methods, from OSL RendererServices (otherwise the constructor fails). The two new matrix methods probably still need an implementation. * Removed deprecated "get_pointcloud_attr_query" and "pointcloud". There are two new routines for pointclouds, function headers for those are there. * Removed the (unused) PARTIO code parts from OSL. It was marked as not tested / not working, and due to the api changes here broken for sure. Code is still in svn history if needed.

Cycles OSL: support for the trace(point pos, vector dir, ...) function, to trace rays from the OSL shader. The "shade" parameter is not supported currently, but attributes can be retrieved from the object that was hit using the getmessage("trace", ..) function. As mentioned in the OSL specification, this function can't be used instead of lighting, the main purpose is to allow shaders to "probe" nearby geometry, for example to apply a projected texture that can be blocked by geometry, apply more “wear” to exposed geometry, or make other ambient occlusion-like effects. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/OSL#Trace Example .blend and render: http://www.pasteall.org/blend/17347 http://www.pasteall.org/pic/show.php?id=40066

Cycles Hair: refactoring to support generic attributes for hair curves. There should be no functional changes yet. UV, tangent and intercept are now stored as attributes, with the intention to add more like multiple uv's, vertex colors, generated coordinates and motion vectors later. Things got a bit messy due to having both triangle and curve data in the same mesh data structure, which also gives us two sets of attributes. This will get cleaned up when we split the mesh class.

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 OSL: support for the trace(point pos, vector dir, ...) function, to trace rays from the OSL shader. The "shade" parameter is not supported currently, but attributes can be retrieved from the object that was hit using the getmessage("trace", ..) function. As mentioned in the OSL specification, this function can't be used instead of lighting, the main purpose is to allow shaders to "probe" nearby geometry, for example to apply a projected texture that can be blocked by geometry, apply more “wear” to exposed geometry, or make other ambient occlusion-like effects. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/OSL#Trace Example .blend and render: http://www.pasteall.org/blend/17347 http://www.pasteall.org/pic/show.php?id=40066

Fix #35896: cycles crash with OSL image textures and viewport + preview render running at the same time.

Cycles: experimental OSL ptex reading code. This code can't actually be enabled for building and is incomplete, but it's here because we know we want to support this at some point and there's not much reason to have it in a separate branch if a simple #ifdef can disable it.
