I'm working on some GP-GPU code on an OMAP 3530-based platform and I'm being stymied by the lack of a glGetTexImage function in openGL ES 2.0. Since the platform uses integrated memory for the GPU, I was wondering if there's any kind of hack I can do to get a pointer directly to an allocated texture in memory. This way I could read my data back without having to push it through the framebuffer, which throws away a lot of data.
