As the topic states, I have no idea of how I could make one of these effects. I have loaded this .tga on a quad, it's got some black parts and everything not black, is transparent. So i've used
.. to make the alpha channel transparent. Now, how do I get one of these "noise/flicker/static" effects on the NOT-transparent areas of the texture? [edited by - sh0rtaaay on January 23, 2003 4:46:36 PM]

If you are trying to achive, what I had in mind a couple of months ago, then do this...

Make a random value for each frame (or time segment) and pass this random value to the alpha part of glColor4f eg.:

glColor4f(1.0f, 1.0f, 1.0f, alpha);

It makes great laser effect where the generator cannot make a static electricity source, so it does not have enugh energy and it flashes ... I hope that''s what you wanted.
