Thank you very much everybody!
The map is a bicubic patch with a bitmap image sandwiched betwen 2 pov-ray
textures. A combination of editing the bitmap image, using a texture map,
and uv mapping is yielding some good results. I was not aware of texture
maps, and the uv mapping is allowing me to curl the corners of the map like
I wanted.
Thanks a lot for the responses and encouragement!
