IMAGE DESCRIPTION:

An empty glass sits on the desk in remembrance of...

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

The wineglass is a CSG object using one of the standard glass textures from
glass.inc.  The bowl of the glass is simply a difference of two spheres, each
scaled slightly differently to make the glass thicker in the middle and
thinner at the top.  The stem is a cylinder, but with parts of the glass cut
away to achieve a "carved" effect.

The stained glass lampshade is also a CSG object, using a custom texture
for the glass and lead.  After discovering that the render time for the lamp
was too long, I redesigned it and cut down on the complexity of the POV source
file -- this resulted in a substantial decrease in the render time.
