]]> Kommentar zu [Note] floating-point/fixed-point operations versus OpenGL von Brian Hoffmann http://brianhoffmann.de/journal/thesis/2011-06-13/note-floating-pointfixed-point-operations-versus-opengl/comment-page-1/#comment-45 Brian Hoffmann Tue, 14 Jun 2011 20:17:17 +0000 http://brianhoffmann.de/journal/?p=249#comment-45 It seems like my initial idea won't work out. I thought I could "fill" OpenGL with some values, let it do some magic (with my predefined functions) and then retrieve the results. I just learnt this is called GPGPU and describes performing calculations on the GPU. For this OpenGL needs some extensions which enable such features especially for certain harware. Since I can only use OpenGL ES, which is a subset of the full OpenGL, I doubt those extensions would work (or that there are some "ES extensions"). So it looks I can only put numbers into the OpenGL pipeline and the results will get drawn into the display -- so I would need to read the "results" out of the pixels (somehow). The OpenGL-for-number-crunching is put on ice until I find a way how this actually would work. It seems like my initial idea won't work out.
