Re: [osg-users] Determine texture memory allocation size

Hi Art, As far as I was bale to find additional info there is no such method in GL specifications ;( Hence my solution is just to compute the size based on internal format and resolution, using the implementation from osg::Image. For my purpose this seems to be enough. It was not clear to me

[osg-users] Determine texture memory allocation size

Hi, does anybody of you know if it is possible to determine the size of allocated bytes of texture in the memory (VRAM or just RAM if swapped). One can compute it by the internal texture format and data type, however I would be interested if there exists some opengl routine which do gives me

Re: [osg-users] Determine texture memory allocation size

Hi Art, Gordon, Sorry Opengl does not provide any such function or capability, you have to track this on your own I'm afraid OpenGL doesn't, but if you install nVidia's instrumented drivers, there are a large number of counters you can query for low-level things like this. I'm not sure
