Oh, I puzzled the master. Wat een eer! ;)
Actually, I just wanted to make a bumpy sphere by subtracting
f_sphere - f_leopard. However, as I neglected to normalize the
input coordinates for f_leopard to the sphere surface, the
3D-ness of the leopard pattern caused disconnected blobs to
rise from the surface. As this would obviously fall apart on
its own (abstract or not), I encased it in a glass sphere,
which also distorted the view a bit due to the ior. As it
was so sphere-ish, I used the CGSphere environment, which
didn't have anything to reflect except the ground plane
so the glassiness is a bit lost on the upper half.
And because this object is full of shadows I had to use a
bit of radiosity but was not patient enough for quality. It
took about 40 minutes on a P4 with just Radiosity_Debug.
I made the texture itself a bit less rougher so the
artefacts would not scream out quite so loud ;)
