I am evaluating how fast calculations on the i.MX53 3D GPU can be.
Now I am a bit stuck since all the examples (and the original target of OpenGL) is always rendering to a display.
What I want to do is
Input data (2D, pixel data) --> GPU (Some per-pixel calculations) --> Output data
I need the output data again in my application.
Can you suggest a way to do this with OpenGL ES 2.0?
