drawing into QImage with OpenGL

[produktdotestow]

Hi,
Does anybody have some example how to draw into QImage with OpenGL? It will be much faster than using CPU. I need pixel by pixel access (for read and write), something like QImage::setPixel() method. I hope You know what am I asking about

Thanks.

See QGLPixelBuffer and QGLFramebufferObject. By the way, "pixel by pixel" is usually not what you get with OpenGL and I strongly doubt using OpenGL for pixel by pixel manipulation would be actually faster than using the raster engine.

Thanks, I'll invent something.
