Week 2

What I did this week

Unfortunately I did not get much done this week, due to University work and some nasty cold.

• I optimized sine / cosine calculations in Cycles, using the sincosf() function in gcc. This gave me a ~4% speedup in simpler scenes. Performance in larger scenes was about the same or just slightly faster. (4f96edd254c6) I have to check on clang, msvc and GPU here still, they have dedicated sincos() functions too.

• I started to look into the uchar attribute support, but no working code yet.

• Fixed 2 OpenCL compile errors in Cycles (master). (94b2852947ab, 4f83d3ec76df)
• Some code cleanup in master. (2c69f1e57458)

• Created a blend with some production tricks to speed up rendering. More infos inside. Download .blend file.
