Thanks for all the answers!
All I wanted to do is to create some 2D effects such as lighting,fire,flares,morphing etc.
I know enough about arithmetics but I lacked technical experience!
Fast pixel plotting?
Well, I''d recommend figuring out exactly what to do and then write a good algoritm that does it.
DON''T USE A SETPIXEL FUNCTION !!!
You need to lock the surface once and then run the algorthm that does the effekt. By using a setpixel function you will loose alot of speed, well, you could just make the funktion ''inline'' and gain some speed but it will still multiply y with the pitch and such things drain speed if you do them alot. Better to do it all at once. And then ofcourse read from smem, write to vmem.

Yeah that''s what I was on about.
So anyone have any figures on which is faster for < 1000 px? Locking the buffer or drawing a point list primitive?

Special thanks to UltimaX!
The code you sent me works much better than I actually needed
And it''s quite all-purpose.
Thanks again

You are mistaken, POINTSTRIPS and INDEXBUFFERS are faster.... no wait.

Am I the only one not getting this? Anyhow, sarcasm is not nice and should be banned. Muhaauhahaa!
