Math has never been my strong point, but am I correct in saying the formula to convert from degrees to radians is... (degrees/180.0f)*D3DX_PI IE, to go from 0 to +1 to 0 to -1 to 0 when using SIN or COS you need to go from 0 to PI*2? Thanks Ray

you might have known that 360 degrees is 2PI...just checkout with 360 degrees and u'll find the above math is right...as simple as that !!

or..
radians = degrees * (D3DX_PI/180.0f)

I prefer this method, because you can pre-compute the D3DX_PI/180.0f value and save it in a constant, this'll save you a floating-point divide whenever you want to do the conversion.

Ah, now that looks more readable!
