No, that's something else. > To expand on this... I almost wrote something like that, but then I considered that I haven't really benchmarked this. Streaming data from CPU onto the GPU is certainly possible and graphics APIs do have hints for such usage. You also don't need to convert to a texture to get arbitrary data on the screen, a trivial shader can do that for you. If your data/transformations naturally live in RAM/CPU, that may well be the most efficient thing to do.
