I am still not sure, how I should do it. (or if it is possible at all). I am rendering 100s of geos into a gemframebuffer once. and then put it on a plane to use as a background image. I would not know where I could apply any antialiasing, because I am not dealing with textures before they are grabed by the gemframebuffer. is there a pix_object that can do some kind of antialias filter? but I guess that must happen already before I am in the texture domain, at the conversion from shape to texture? or is antialiasing an oversampling of actual pixel data? like a texture 2000*2000 gets antialiased to 500*500? thanks, marius.
