View Full Version : hardware matrix multiplications

Hi !
I'd like to know : with "T&L" hardware, when I call glMultmatrix, is it performed by the graphics hardware ? if not, how could I fix that ?

Thanks in advance !

That dependes on the implementation. If I remember correct, the GeForce series does not perform matrix/matrix multiplication in hardware. And there is nothing you can do to fix it.

But why bother, a matrix/matrix multiplication can be done as fast on the CPU as on the GPU, and you don't do them very often compared to matrix/vector multiplication anyways.
