Not an incredibly exiting image, but this is real-time, incredibly fast motion blur in action. :) I assure you it looks awesome moving, although I cant release any binaries due to the nature of the project, sorry. :P

Incredibly easy to do, all you need to do is disable clearing the Color buffer and render the scene with a low alpha, like glColor(1.0, 1.0, 1.0, 0.2), and viola! Fast and quite cool looking. :)

Only problem is that the objects become transparent (obviously) but this can be fixed by sorting and rendering the polygons front to back. And the problem here is that if you use alpha in any of your textures you'll get wierd results.

But I'd imagine for in-game cutscenes or merely incredibly fast-paced games this effect would prove quite handy, since there's almost no performance hit at all.

Has anyone ever tried this method before? And are there better ways to get around the 'transparent object' problem? Let me know.
