These macros generate height field meshes from pigments from within POV.
SquareHF.jpeg is an ordinary square height field, like the
height_field {} primitive object in POV.
SphereHF.jpeg is the first type of spherical height field, using a 2D
square wrapped around a sphere with spherical coordinates.
Sphere2HF.jpeg is the second type of spherical height field, generated
by recursively subdividing an octahedron, dividing each triangle into 4
triangles. This doesn't have the "pinching" toward the y axis like the
first type does.
I still haven't done smoothing, I'll try to figure out a good way to do
it.
