I'll have to download that. When trying to stitch pieces of 512x512
height fields together, are there still visible seams when using erosion?

Really, I've got only two functions so far: the angle map and the edge
map. The edge map is just a hack from a previous proximity pattern.
The red/green importing functions are just useless novelties. I was
learning how to decode/encode 16-bit data for another project, which, in
the end, won't need that kind of functionality anyway.
Hopefully the angle map can be used to displace pigments from from an
isosurfaces according to angles. This should overcome problems arising
when displacing isosurfaces based on height field data. There might be
another way to do this. It wouldn't be the first time I've tried to
solve a problem the hard way ;)
I was beginning to regret having mentioned this set of macros, but maybe
you guys will find a good use for them.
