Glowing effect? (Read 980 times)

Glowing effect?
Mar 6th, 2008, 2:02am  
I really want to understand how to make something (let's say a sphere) glow diffusely, ideally blending with other spheres. The eventual goal is to have them glow brighter / dimmer in time with music.

Problem is, I have no idea how to do this Smiley The following link has a great representation of what I am after, can anyone help me out? I understand that noise is involved, but the code was not documented at all, so the interesting stuff is meaningless to me.

If it works how I suspect, each sphere is actually just an image with an alpha channel, and they're blended together.

If I understand what it is you're trying to do, I had the same question when I first dived into Processing and managed to produce something similiar using simple textures and additive blending.
Check out this link - http://www.flight404.com/blog/?p=71 - it provides a nice starting place. Otherwise, drop me an email and I can send you some working code / texture examples.
