Ok, I have a program where I want something to rotate around its Z axis. That works fine using glRotatef() when its in the center of the screen, but when its not, it rotates around the center of the screen. How can I get it to rotate around its center, and not the screen''s center ? Any help/suggestions would be much appriciated.

make sure you move the object before you rotate it. I think.
