View Full Version : HW Rendering to offscreen buffers

SGI did it with their visual workstations in windows (using an "pbuffer" extension). It would be a whole new path for developers to do cool tricks. I guess I'll be happy enough with a HW render to texture in video to begin. The current way of glReadPixels or glCopyTexImage are ineficient and in many cases unoptimized (fall back to software).
