    Hi,

    process of elimination: You must set a current opengl context, then call glewinit() before being able to use any glew. Have you done so? if not, it might help.

    let us know.

    Your next step should be to read something like this to understand how gluLookAt works. So loop back there to save us re-interating here.

    I would more likely assume it relates to each call to things like glVertex3d. last I saw(anybody can correct me if things have changed) the...

    This is a common problem that occurs as the number of objects in the scene increases. Not so much because glReadpixels becomes the bottleneck, but because the searching technique used to find the...

    Hi wmelgaard,

    How you going with the opengl drivers?

    Are those rectangles supposed to look like cubes?

    I would try using less extreme vaues in glFrustum:
    e.g.
    glFrustum(-1,1,-1,1, 1,100);
    and not call glOthro() to see what results.

    Why are you still using glFrustum() aswell as glOrtho()?
    What happens if you eliminate the glFrustum()?
