A few years ago, in graduate school at Texas A&M, I took a class about generative methods - kind of a superset of procedural generation. Check out my class website at http://students.viz.tamu.edu/bensuth/Generative_Art/Generative_Art.html . It's all a bit old now, but it was fantastic fun.

Hm, interesting. I suppose that would be a much more efficient method for point-glow sources than a separate rendering pass. I suppose the glow textures are just added or multiplied together for the glow in the center. Thanks for the help. If anyone has more in-depth explanations, I'd appreciate tha...

The glow effect I'm talking about is here:
I'm almost positive that the souls themselves are sprites, but is the background glow also a sprite? That seems unlikely given the glowing center, unless that's done with a separate sprite.

I'm currently working on a simulation visualization of ant pathing as part of my thesis, and part of that visualization involves a glow effect which I'd like to be very similar to the "soul glow" found in Darwinia, specifically in the main world screen. Could anyone help me figure out how ...
