Brecht Van Lommel	1eeb846e78	Fix Cycles viewport render not updating when tweaking displacement shader. ... This was disabled to avoid updating the geometry every time when the material includes displacement, because there was no way to distinguish between surface shader and displacement updates. As a solution, we now compute an MD5 hash of the nodes linked to the displacement socket, and only update the mesh if that changes.

Sergey Sharybin	0579eaae1f	Cycles: Make all #include statements relative to cycles source directory ... 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.

Brecht Van Lommel	db1664ed4c	Cycles: ... * Compute MD5 hash to deal with nvidia opencl compiler cache not recognizing changes in #included files, makes it possible to do kernel compile only once and remember it for the next time blender is started. * Kernel tweak to compile with ATI/linux. Enabling any more functionality than simple clay render still chokes the compiler though, without a specific error message ..	2011-09-03 10:49:54 +00:00
