The Inferno panel lets you create explosions, fire,
and smoke effects by combining the lens flare glow
with black and white fractal noise.
The Glow inferno effect is like the Inferno effect
in

, but it is applied to the
Glow through the R, G, and B color channels.

areas, often used for fires.
Electr icLong, well-defined tendril pattern that
can be used to produce arcing electr icity, when
animated. By adjusting the quality of the pattern
to 0, you can create the effect of water reflection.
Reseed—The number that the fractal routines use
as a starting point. Set this spinner to any number
to create different fractal effects. The Reseed
button randomly selects a new number.
