Re: How to draw circle use openGL?
if you can draw a circle, you can easily move it like you move any other object - pushMatrix(), transform / rotate it into the right spot, draw the circle, then popMatrix();

Re: How to draw circle use openGL?
You can either do it manually (google "openGL circle" to find code)
*or* a good way is to use quadrics: http://jerome.jouvie.free.fr/OpenGl/.../Tutorial7.php
