I just finished adding turbulence to the glow patch, it seems to work
pretty well. Here are some of my experiments with it:
Lamda, omega, and octaves were left at their defaults.
turbulence1.jpg has a turbulence amount of 10 and turbulence scale of 1.
turbulence2.jpg: amount 0.35, scale 0.1
turbulence3.jpg: amount 0.5, scale 1
I am still working on making the turbulence scale feature work with
patterns and ordinary warps as well as with glow. The current syntax
just adds an optional vector parameter following the existing "amount"
parameter.

That looks pretty good, maybe some kind of fast alternative for media in some
cases. The turbulence scale could be quite useful for other stuff too, hope you
manage to make it work ...

Which has me wondering how this will mingle with media. It's a waiting game
:-)
Patterns too? Wow...
You know what would be completely fantastic is some sort of way to have the
glow emitting light, some kind of shaped light then and --- oh, okay, I knew
I was dreaming.

The contribution of the glow effect will simply be added to the total
pixel calculation, so it really depends on *how* you are using the media.
> Patterns too? Wow...
No patterns, just turbulence.

For that, you can use MegaPOV radiosity and media.

If you only need a constant color, it will work as a kind of emitting
media.

I think I have it working...there was some code that I had to "fix"(it
wasn't doing anything wrong, but it was doing things the wrong way), but
it compiles and scaled turbulence works fine in the glow effect. I still
have to test it in warps, fog, and whatever else uses turbulence,
though...and there are some strange places where turbulence is used(some
patterns, like agate, marble, spiral1, and spiral2 override the usual
turbulence calculation), which I am not sure will interact with it as
expected.

I will release a version having this feature but not the proximity
pattern soon...the reason for leaving the proximity pattern out is that
I am currently right in the middle of totally rewriting it.
