Hi there,
I’m trying to get frame buffer using glReadPixels, but it is too slow.
- For 720x480, the time is 50ms.
- For 1280x720, the time is 100ms.
I use PBuffer to render “offscreen”.
Is there anyway to make glReadPixels faster?
Thank’s a lot.

Use Frame Buffer object
you need to google next opengl commands: glGenFramebuffers, glFramebufferTexture2D
