An OpenGL question...

... On a Purebasic forum, I know

I need to find a way to get the image drawn in the opengl viewport and to put it into a Purebasic image.
I thought at a start I could use glReadPixels, but I just don't understand how does it work...

Nobody ?
I found a way to put what is rendered on the viewport to a gltexture, but it's not what i want, i want the pixel datas...

Why not share your findings, either here or in the 'tricks n' tips' section!

No, I mean, i figured out my error, in fact there's nothing special about glreadpixels...
However, this function is sloooowwwwwwwww !!
Is there another way to do that fast ?
