Brecht Van Lommel	649dd6f648	Fix cycles crash on some processors. We actually need S-SSE3 support for this ... new BVH traversal code, not just SSE3.	2013-06-18 16:52:02 +00:00
Brecht Van Lommel	d57c6748c4	Cycles: optimization for BVH traveral on CPU's with SSE3, using code from Embree. ... On the BMW scene, this gives roughly a 10% speedup overall with clang/gcc, and 30% speedup with visual studio (2008). It turns out visual studio was optimizing the existing code quite poorly compared to pretty good autovectorization by clang/gcc, but hand written SSE code also gives a smaller speed boost there. This code isn't enabled when using the hair minimum width feature yet, need to make that work with the SSE code still.	2013-06-18 09:36:06 +00:00
Thomas Dinges	11707119de	Cycles: ... * Code cleanup, remove unused "resolution" variable from the DeviceTask class, was never used.	2013-05-14 21:18:20 +00:00
Brecht Van Lommel	7c9d993347	Fix cycles intersection issue with overlapping faces on windows 32 bit and CPU ... without SSE3 support, due to 80 bit precision float register being used for one bounding box but not the one next to it.	2013-02-04 16:12:37 +00:00
