Hi, I'm a former DBP user and I have decided to now use Blitz3D to fullfill my needs (I was just P***ed off with all the bugs & lack of support).

Anyway, I've been looking through the codebase and have downloaded all the motion blur source codes, which are very good! Heres the thing I want to be able to code/understand it myself but I don't understand the technique being used, please could someone explain (in detail) how to code this effect.

I'm not asking for source code but more of explaination of what is going on, I know sprites are used but I'm not sure what/and how they are creating the effect.

Thank you, and I'm glad to an offical blitz user (bought it yesterday and well worth the £60 it cost me!)

Kind Regards,
Gamzman
