I'd like to display large images for a software using 2k, 3k or even 4k images. Using native API is quiet slow (Linux, Windows...).
I've chosen to use OpenGL and hardware accelration to get it worked. I've tied a way to implement it, but i'm definitly sure it's not the best.
I'd like to know your suggestions ?
Regarding the function glDrawPixel() don't even think about it !
Tanks a lot,
