Hey guys, I need to find a fast way to get the frame buffer. Using glReadPixels is taking me down to about 3 fps (only rendering a 1 triangle scene), and that will NOT be acceptable.
First, I have constants:
- Screen will always be 512x512
- Bitdepth will always be 32bit rgba
- Platform will always be win32
Anybody have some interesting hacks? I bet there are some win32 calls I can use to make this a bit faster, but I’m not much of a win32 guy.
Machine configuration is a 550mhz P3, TNT2 AGP card.
Maybe Nvidia has an extension for this?
