Motion Blur
Motion blur is a planned function in my upcoming 3dengine.
You can use accumulation buffers to do that or program your objects with different positions and degree of transparency.
You can save 4/5 last positions, and give them increasing alpha values.
Current position is alpha=1 (solid), while farthest is 1/position number.
Better idea, comments... are welcome.

I figured out a really easy and really fast form of motion blur. Simple, Instead of clearing with glClear or whatever the opengl clear function is, just render an alphablended rectangle that is already transformed to the screen. Really simple and effective.

nes8bit, wouldn''t that only be for scene (or portion of screen) motion blur as opposed to object motion blur? if it works for object motion blur, please inform us more on this super cool technique, cuz i''d like motion blur in my game too.

Sorry.
Isn''t the only possible way: to use alpha blending and just draw the object in it''s previous positions with more or less blending?
It may seem faster to save each rendered object in a buffer, but with current hardware acceleration it''s better to just redraw the polygons again!

I''ll post a demo on my page of what I''m talking about later...

ha ha! nes8bit, was your idea the same as at glvelocity.com? if not, it may still be worth it....
