thanks chris, thanks johannes -
You could use pix_snap and put that into pix_buffer. It will be slow.
oh my, that's certainly true.
its getting worse with higher frame rates and larger render windows - so pix_snap does those dreaded memory transfers, right? this is a real bottleneck ... does opengl allow for memory transfers on the graphic card itself?
well, yes: that's what [pix_snap2tex] does. however, [pix_buffer] is non-openGL but instead just handles data in main memory.
