hi evan,
has anyone got a shader working for manipulating a texture on os x (gaussian blur, or enhance, or some other effect)? can i take a peek at the code? having some trouble getting it to work over here and not sure where the errors are.i haven't tried this, but you might find the ffglcifilters useful. these are osx ffgl plugins that implement all kinds of effects on a pixel primitive.

best, gabor
