[Bf-committers] GSOC - Math Library Project

[Konstantinos Margaritis]

FWIW,

I'm already working on this, I've committed patch #8296

https://projects.blender.org/tracker/index.php?func=detail&aid=8296&group_id=9&atid=127

Also, I've split the modeller and renderer math libraries, and in the 
renderer I've fixed some issues like SIMD alignment, added some 
AltiVec (SSE & Cell soon to follow) optimized functions and 
reorganized the structures a bit in order for the Cell port to be 
easily done (which was my main task actually). I was entangled in 
some other projects the past days but i should be able to begin again 
this weekend.

(Disclaimer: I'm not a student and therefore not liable to apply to 
GSOC, I'm running a company specializing on AltiVec/Cell programming, 
and I chose Blender as a way to demonstrate my work)
