Thomas Dinges	49df707496	Cycles: Calculate face normal on the fly. ... Instead of pre-calculation and storage, we now calculate the face normal during render. This gives a small slowdown (~1%) but decreases memory usage, which is especially important for GPUs, where you have limited VRAM. Part of my GSoC 2014.	2014-06-13 21:59:13 +02:00
Sv. Lockal	e7c2578576	Cycles: avoid 1.0f/(1.0f/x) divisions, which msvc (only) can't optimize. ... This makes bmw scene in msvc 12 builds 6% faster. It also gives a minor speedup for SSE hair in all compilers.	2014-04-03 22:08:53 +04:00
