IMAGE DESCRIPTION:

  Just a few items of glass put out for a display on a low corner table.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

  Force. No modelers were used. Tough guys do it this way.. :) Though I
haven't yet found a modeler that would do anything but confuse me.

  Objects are just CSGs of boxes, spheres, cylinders, torii - the usual
stuff. Most of them are more complicated than they look - the render did
not really 'get inside' the glass, or into the detail. The decanter is the
biggest CSG object, with the decor created with a pair of #while's. Maybe
POV's bounding did not really get into that, since rendering it took
terribly long (3.8 million triangle intersection tests) though the long
render time was mostly due to the high max trace level. Lowering the ADC
bailout did not help much. I basically created them one by one and ran a few
(dozen) test renders to get them look right. The area light was the other
major slowdown, though not as severe. The objects are quite simple.

  Textures are mostly just basic POVray includes, unfortunately; I'm not
good at those. Three glasses (Glass3, Green_Glass, NBglass) were used, a
chrome metal and the bottom layer of the table texture were supplied. Others
were just thrown together quickly, but the result was good enough for my
needs. The crand-like effect on the walls is a granite normal; no
irreproducable effects for me. A few cliches, too: Checkered floor, wooden
table, and such. Well, raytracing is pretty new to me still, and this is the
second or third more complicated scene that I've done. I thought of making
the table a mirroring or smoky glass, but that didn't look good.

  The font 'eklektic.ttf' is not included, but any bulky gothic font will do
fine as well.
