You can combine an isosurface with the height field data, I can't remember
exactly how I did it, but I did do it at one point. I think it involved
turing the pigment containing the image map into a function, and then using
that as the function for the isosurface. I would check the scene file for
it, but I'm not sure if I still have it, and besides, it's not on the
computer I'm using at the moment.
