I come from the Flash world, so hopefully what I'm asking makes sense. As far as I can tell, there isn't anything built into OpenGL ES 1.1 to do this:
I'd like to be able to blur a texture, either using gaussian blur, or box blur, or anything else that works :) It'll need to be fast enoguh to do it every frame with a 320x320 texture. Is it possible? I've been looking around both here and on Stack Overflow and I haven't really found any solid answers or examples? I don't need actual code, just a poke in the right direction if it's doable at all.
FYI, I'm trying to do a blurred motion-trail technique, where you blur the texture and then draw an object to it, but you never erase the texture, so every frame you end up with a blurry-er motion trail.
Thanks,
