Hi,
I’ve managed to totally confuse myself with perpective projection, if I set up the projection matrix with say:
gluPerspective(60.0, float(width)/float(height), 0.1f, 200.1f);
and then I go to draw a unit sphere that is positioned at (0, 0, -100) what should I scale the sphere by to make it fill the screen?
Thanx,
Tumbleweed.
