This isosurface shape is made by applying a "sphere
inversion" to a cubic grid.

Peter C. Capasso's "circle inversion 2" image inspired
me to do this. It can be found here:

  The grid that is "inverted" is similar to the grid in
my "Iso-Cubism" image:

  It's a pity that I probably will have to wait years
for affordable processors that can render this shape
with a nice texture, radiosity and photons.

This image was made by blending two rendered images
in Photoshop LE. The first image was rendered with
shadows and the other without.


Here's some theory about "geometric inversion":
