[osg-users] Read frame buffer back into main memory

[Antoine Rennuit]

Hi all,

I need to read the frame buffer back into the main memory. I know this will kill performance but I only need to do it once.

Is there a way to do that? I could not find clear answers on the internet.

Thanks,

Antoine.
