Hi guys, I am a newbie on OpenGL and i have to create a presenation about GPu techniques. So i thought want to compare a matrix multiplication on different APIs. Now to OpenGL: I have searched for a while but i couldnt find anything... So my question: In general, is it possible to calculate a standard matrix times matrix multiplication with opengl? I want to calculate M=MxM on GPU, not on CPU! I dont want to create windows/scenes or any kind of geometric figures etc. Can you help me with some little advices? I found the 4x4-matrixclass of OpenGL, but my multiplication shoud be like 1000x1000 or bigger ... so is there any kind of possibilty to realize this MM on a simple way in C++? Best regards Alex :pimp:
