I've found a pretty convenient tool for getting heightfield elevation maps
Now I just need to figure out a way to make the heightfield, the satellite
image, and the street map align and be scaled properly.
I also have "holes" in my heightfield when I try to texture it with an image
map. They appear to be at places that are over a certain elevation. Does that
ever happen? CAN it ever happen? I'd expect an image to be rgb in the range
Is there a mechanism in POV-Ray to scale the rgb range of a heightfield image to
the proper range?
