Hey guys, I'm trying to add a nice nifty ambient effect to the lava in my game, so I was thinking of using the Tron glow effect on all the lava tiles.

I've done some scouring on the net via Google and found this lovely article on the matter:

Real-Time "TRON 2.0" Glow For Low-Spec Hardware

and of course it's older cousin: Real-Time "TRON 2.0" Glow in Half-Life

but... it's very Half-Life Engine specific. And I fear that it doesn't really cover the theory very well at all. So I'd like to get the basic concept of it before I delve into the code, just to make sure if I can make any use of this or not.

So who knows more about this?

EDIT:

Ah ha! I knew it... found the article (I remember there being this one somewhere just couldn't remember where.) Real-Time Glow on Gamasutra.
