Now the big (1280x1024) render of my glass sphere with bubbles are finished.
It took about 5d 12h...
The image is postprocessed to remove the ugly effects of the dispersion bug
(see my post "Despersion bug?" from 2003-03-21). It seems that the bug is
only in the red channel so I just removed all red from the sphere (cyan
glass looks good, but it was supposed to be clear).

You could base the red channel on the others and get the sphere clear again?

Wouldn't that kill the dispersion effect? The red channel is supposed to be
different. Maybe download and recompile the POV source (if you have a C++
compiler handy) but beware of possible conserve_energy bugs! (or maybe it's
just me...)

I have a MSVC compiled version now, but that still shows some strange
things, see "Bug with dispersion" in povray.general.
What is the conserve_energy bug you are talking about?

I don't have an unmodified source tree handy right now but (at least in my
patch) there's some issues with internal reflection. It could possibly just
be my patch though...
