Yeap, I'm working on some explosions/missiles/gun-fire right now.
One of tricks You mght find usefull:
sphere { 0 10 media { ambient ... turbulence 0.1 } } - the fire
and now:
sphere { 0 10*2
pigment { ... } finish { ambient 0.3 }
no_image no_reflection no_shadow
}
the second sphere, if rendered in MegaPov 1.1 - generates _only_ radiosity
data. It could be used for example to better lighten a big room, there is a
better chance for radiosity-ray to hit the "bounding" sphere and therefore
to generate light, while with low count-quality some rays may not hit the
smaller sphere and generate unwanted radiosity errors.
