comment Why are radians preferred over degrees in game development?
@DMGregory That was what I meant with "inherent rounding error with Pi". The other option is to not use singles/doubles but a way to represent numbers as factors (so representing 2*pi/360 not as the result of the calculation but as that formula) and only calculate the result when needed. I don't know if any "real" programs do that, but stuff like Mathematica can always represent "1/3" as "1/3" instead of "0.333333.....". But after going through the numbers I guess you're right, the rounding error is there but insignificant

Thanks, also to @DMGregory who pointed out FCOS/FSIN. I blogged about my understanding: stum.de/2013/12/22/game-math-radians

comment Why does the order matter in multiplication of matrixes?
@Zhen The weird thing (to me) is that I'm not doing a rotation and a translation. I'm only doing scaling - existing world * scale or scale * existing world seem completely equivalent. It's the Row vs Column stuff that is the case here, I wasn't aware that matrix multiplication in general math isn't commutative.

I installed VS2008 today, sadly that MSDN download didn't contain the XACT documentation :(
