That's double precision (64bit)... How accurate does POV need them?

My program represents the camera orientation as quaternion - it coverts 
it to matrix representaion before exporting it. If there already is a 
matrix representation, POV should be able to use it :-/

Do you know how to convert orientations represented as quaternions or 
axis-angle pairs into fixed-angle representations (for use in POV's 
rotate <x,y,z> command)?

Thanks
