Hi,

I think this is my first posting to this list. But I'm using povray for quite
some time now. I posted first to this news-server about 10 months ago and
asked how to do a candle flame - the rendering below uses the almost
unmodified code I came up with back then :)

I've been working on this test scene for about 2 weeks now, and finally
realized that radiosity seems not really good for small light sources. You can
read a bit more about my progress with it at http://www.elias.f2s.com/pov.

The scene uses no light source at all, and all of the radiosity comes from the
candle-flame, which is a media contained in a sphere. I was cheating a bit
with the lighting, and set brightness to 3, assumed_gamma to 1, and gave the
plane a diffuse value of 10.

Render time was 86 minutes on a P3-933Mhz-128MB.

Thanks for any comments :)
