So you can see all your scene in the gemwin and snap only one part. This is the same with [gemframebuffer]. You can snap only one part of the [gemframebuffer], that depend of the order of the rendering. Then you don't snap 'things' in the gemwin. > > That is I need to get the texture off the gfx card, back into pix_ > domain, *without* using the gemwin to do it. You can share the pix_ with [pix_share_write] and [pix_share_read]. As Chris says, it should be faster with GLSL and the work on textures, because [pix_snap] is slow. Hope it's enough clear and i didn't make a mistake ! ;) ++
