2017-03-29	Cycles: Make all #include statements relative to cycles source directory	Sergey Sharybin
	The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

2017-01-19	Cycles: Remove using namespace hell	Sergey Sharybin
	Please NEVER EVER use such a statement, it's only causing HUGE issues. What is even worse: it's not always possible to immediately see that the hell is coming from such a statement. There is still some statements in the existing code, will leave those for a later cleanup.
2016-10-24	Cycles: Remove explicit std:: from types where possible	Sergey Sharybin
	We have our own abstraction level on top of the STL's implementation. This commit will guarantee our tweaks are used for all cases.

2016-09-18	Cycles: Adaptive isolation	Mai Lavelle
	Idea here is to select the lowest isolation level that wont compromise quality. By using the lowest level we save memory and processing time. This will also help avoid precision issues that have been showing up from using the highest level (T49179, T49257). This is a pretty simple heuristic that gives ok results. There's more we could do here, such as filtering for vertices/edges adjacent geometric features that need isolation instead of checking them all, but the logic there could get a bit involved. There's potential for slight popping of edges during animation if the dice rate is low, but I don't think this should be a problem since low dice rates really shouldn't be used in animation anyways.

2016-09-15	Fix T49179: Parts of mesh disappear with adaptive subdivision	Mai Lavelle
	Problem was zero length normal caused by a precision issue in patch evaluation. This is somewhat of a quick fix, but is better than allowing possible NaNs to occur and cause problems elsewhere.
2016-08-24	Cycles: Fix crash when empty mesh has subdivision	Mai Lavelle
	OpenSubdiv doesn't like empty meshes, so we need to be careful not to subdivide when the mesh is empty.
2016-08-18	Code cleanup to use array.data() rather than &array[0]	Brecht Van Lommel
	(Now without the build errors)
2016-08-18	Revert "Code cleanup to use array.data() rather than &array[0]."	Mai Lavelle
	This reverts commit 40b367479c6fe23d6f2b6d822f2d5266485619f3. Didn't build or solve any known issue. Please don't push changes without testing them first.
2016-08-18	Code cleanup to use array.data() rather than &array[0].	Brecht Van Lommel
	These latter can cause MSVC debug asserts if the array is empty. With C++11 we'll be able to do this for std::vector later. This hopefully fixes an assert in the Cycles subdivision code.
2016-08-07	Cycles microdisplacement: Support for Catmull-Clark subdivision via OpenSubdiv	Mai Lavelle
	Enables Catmull-Clark subdivision meshes with support for creases and attribute subdivision. Still waiting on OpenSubdiv to fully support face varying interpolation for subdividing uv coordinates tho. Also there may be some inconsistencies with Blender's subdivision which will be resolved at a later time. Code for reading patch tables and creating patch maps is borrowed from OpenSubdiv.

2016-07-29	Cycles microdisplacement: ngons and attributes for subdivision meshes	Mai Lavelle
	This adds support for ngons and attributes on subdivision meshes. Ngons are needed for proper attribute interpolation as well as correct Catmull-Clark subdivision. Several changes are made to achieve this: - new primitive `SubdFace` added to `Mesh` - 3 more textures are used to store info on patches from subd meshes - Blender export uses loop interface instead of tessface for subd meshes - `Attribute` class is updated with a simplified way to pass primitive counts around and to support ngons. - extra points for ngons are generated for O(1) attribute interpolation - curves are temporally disabled on subd meshes to avoid various bugs with implementation - old unneeded code is removed from `subd/` - various fixes and improvements Reviewed By: brecht Differential Revision: https://developer.blender.org/D2108
