Hi,

    If I had a candle flame modeled in Pov would it be possible
to have it radiate light in the same manner as a real candle flame.
By this I mean is there a way to calculate the inverse square law
that a normal unreflected candle flame is physicaly bound by.

Is

Section 7.5.6.7
Light Fading

what you're looking for?

Hi,

I have made a pretty nice candle for my submission to the math/science IRTC
entry (May-June 1997). The flame is a bit torch-like but you can fix that.
Otherwise it features drops of molten was (one of which hasn't yet cooled
down and is clear and refractive), a pool of molten wax under the flame, and
that "seat" (?!?!) that you make from a few drops to stick the candle on. If
you want I'll send you (or post in one of the scene-files groups) the
source. As of the lighting side of it, it does what you want plus it
illuminates the candle itself.

Peter

  Actually I wanted to go through the learning curve myself as
far as creating a flame. It was the theoretical behavior of the
light source I'm interested in. I didn't RTFM enough concerning
fade power and fade distance to realize that they do follow the
inverse square law fairly accurately.
Thanks for the offer though.
