Thanks. I was experimenting with my latest macro, which generates a
sphere from a set of hyperbolic non-cartesian splines. The results still
leave a little to be desired, but I'm working on it. The plane uses a
macro I wrote a while back, which averages several 3-d trigonometric
waves to approximate an infinite, flat surface.
What looks like a sky_sphere is in fact an infinitely large polynomial
surface defined in Hilbert-space; one of my first experiments with
isosurfaces. I quite like it.
