The sphere is broken.  There can be no more.  This is the end of raytracing
as we know it....

This image took *way* too long to render.  I started it before the weekend
thinking it would be done when I got back, but what I wrong!  It was only
70% done with 0 PPS.

The half-spheres are isosurfaces chopped in half with an iso-plane and a
combination of bozo and crackle pigment functions.  How was the crack in the
sphere done?  A marble pigment function of course!  I then shot some photons
and this is the result.  The two parts don't quite fit together.  As a
matter of fact, they are exactly the same.  I tried to subtract the iso
sphere from a whole sphere but that didn't work well.  I think it's a bug
which I will demonstrate later.  It actually sounds similar to the blob
problem posted the other day.

It would look so much better with area_lights but due to the time it took to
render (115 hours - 7 hours of photon processing) I couldn't dare add them.
In my opinion, I smoothed the crackle pigment too much.  I'll fix it if I
ever decide to re-render it.

Enjoy,
Richard.
