How can I blur the rendered frame (I mean, for everyframe) ??? I mean some kind of blur like gaussian blur in Photoshop ...

the trick is to draw the frame several times all at once, each with a little offset, and use correct blending and transparency methods (fade). on glvelocity.gamedev.net , you''ll find a cool demo about motion blur (in openGL). you''ll need a fast card for this one, though..

No ! :o)
not motion blur, gaussian blur

Look for a Gaussian blur algorythm :p

Render the scene apply filter to the resulting 2D image and display it.

I don''t know any link to Gaussian blur code/theory.

-* So many things to do, so little time to spend. *-

You can achieve some kind of blur with image filters. I don''t know how Gaussian Blur is achieved.
