Hi all, I would like to know if there is a way to record a [gemframebuffer] into a [pix_buffer 1000] my goal is to be able to record a gemchain animation (5 seconds maybe) and replay it (forward, backward, etc) I know that [pix_snap] with [pix_buffer] could do the job, but it eat a lot of cpu, so a solution with [gemframebuffer] would be better...
no. the problem you have is that you have to transfer whatever is rendered into a framebuffer (whether this is [gemframebuffer] or [gemwin] doesn't matter) back to main memory (which is what [pix_snap] does), and that is usually slow.
you might try to use a shader to transfer data within texture-memory (rather than between texture-memory and main-memory)
