g'day,

in case any of you are using my quaternion code, i've uploaded a new zip (same link -- check my sig if you can't find it) which also contains quatRad.c as an alternative to quaternions.c.

quatRad uses doubles instead of floats, and uses radians instead of degrees. this update is due to a devastating recent discovery that objects won't rotate less than about 2.5 degrees (slightly smaller values get rounded up) in a frame. by using doubles and radians, quatRad will rotate as little as about 0.1 degrees in a frame.

enjoy,

julz
