Thanks for the prompt reply. I will try your suggestions, but I still need
povray anymation features [i am creating a short clip], so i will need to
find other creative ways to make this work. I am also worried about
maintaining the depth field between frames in an animation.

Also, is there an easy way to concatenate the 2d color image and the 2d z
depth map into a single image?
