zzuegg: > `RadiansToDegrees(mLateralSlip);` Yes, seeing this in library code for anything other than user-facing values would make me suspicious of the rest of the math. Just too easy for there to be some case somewhere else that is expecting radians and not getting converted back. Instant (but slight) distrust of authors that have trouble picking one or the other when the choice seems clear. It could be that your troubles when using the ‘correct’ values stem from some math error in the library due to this. (shrug) Whether true or not, it would always be in the back of my mind. (I come at this from experience because one of my first self-developed 3D engines tried to walk the line between API-facing degrees and ‘real math’… and so many bugs came from that.)
