Does anyone out there know of a means of converting a three dimensional
image into a simple line drawing? In other words, is there a way of
getting the program to outline the picture? If photoshop cannot do this is
there another program that can?

Here is a method that I have used to extract outlines from 3-D
rendering. The trick is that you need to generate a special image:
the scene must be rendered with no shading, and simply colored by
depth. So, objects close to the viewer are white and objects fade
to black in the distance. You then run this depth-shaded image
through any edge-detection filter, and by appropriate modification
of the color map, you can get nice outlines. You can then composite
them with a color image to get a nice final product.

Good luck!
