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

Next week

Same as last week.

Questions

None.
