Post Processing?

Are there any extensions that could be used for post processing of rendered OpenGL images? Something like changing the contrast, applying gaussian blur or something like that...
Regards,
Lyve

Not really. The standard aproach is to read screen in texture, filter it if needed, then render it back to screen. Using ARB_FP you can get almost anything you need.
You should never let your fears become the boundaries of your dreams.
