Here is the source for the Isosurface golden egg I posted in
povray.binaries.images. This uses the Isosurface patch (in this case,
in the SuperPatch). The "5" and "6" could be made variable and the
shape could easily be recast as a macro or as 3.02 isosurface code. The
egg runs from y=-1 to y=1 along the y (up) axis with the narrow end on
top. I modified the formula from a Ken Perlin C snippet. Maybe someone
will find this useful.
