Would be great if someone could help me understand the points on openGL. FOR example
glVertex3f(1.0, 1.0, 0.5) ---- stuff like this, what determines where my origin is going to be, and how do i know how far it will move. im a little confused with this. I understand where each one is going in terms of x, y, z coordinates, but i can never get a shape going that i want, really annoying!!
Thanks.
