Stan, When performing a rotation around the X axis for example, is the positive versus the negative direction defined? Can a negative number be used? If only postive values are accepted, how does Turbo define the rotation – towards the secreen or away from the screen? I finished the animation of rotaing glass prism last night and the results are truly spectacular.

Shalom – Rotations are on a left to right orientation. When you need to change the direction, simply flip the axis. I'm anxious to see the animation. BTW your VD-1 digitizer will absolutely go out by Friday.
