I'm just beginning to look into adapting shaders for use in Jitter. I'm

trying to get a "warp" effect - I'm thinking that using some sort of

displacement shader would be more efficient than the method I've pasted

below. Is there a way to produce the same effect in OpenGL? - especially

one that is significantly less expensive?

Any advice or pointings in the right direction is appreciated.

Check out td.repos.jxs as well as the other texture-displace shaders.

You could probably use it as is, but you could also use it as a starting 

Another (non-shader)technique would be to use the surface geometry to do 

your distortion. Check out Jitter Recipe #18 for an example:

Hi Bart,

You could probably use it as is, but you could also use it as a starting 
point for further experimentation.
