Hi, I searched the Net in and out for a good motion blur example (pure WinAPI), but couldn''t find one. So I did a little thinking and implemented it myself. Well, sort of... Here''s how I did it (is it the correct way?): every frame I simply draw the blurred object some n frames back, each frame with a higher alpha value, resulting in something horribly slow on my machine. Is this normal? I know my gpu is antiquated (Riva TNT 2), but from the looks of it I''d say it only draws some < 10 fps (1152x864). Thanks, Crispy

pure WinAPI on an OpenGL forum...?
Yes that''s how it''s done. Of course it''s slow, you have to render everything multiple times. OpenGL has an accumulation buffer for it, don''t know how well it''s supported though.

Where''d the engine go? Where''d it go? Aaaaaah!!

i have seen a cool motion blur effect in MotoGP (a new game). I wonder how they did it.

IIRC, www.gametutorials.com has a pure WIN32API tutorial on motion blurring. I remember seeing one around the sites I visit though. I wish I could remember for sure.

I asked one of the Black Robes why the Deceiver wasn''t going to stay to defend the dam, and he tersely replied: "He goes to warn the Emperor; moving through odd angles, faster than any man, and if unobserved, much faster than that."

I meant without the use of MFC.
