Any point on a circle is circle_radius away from the centre of the circle. I just made a loop than created a box around the circle and set the centre of the circle to be the 'mid point' of the loop. E.g - - - - - - - - - - - - c - - - - - - - - - - - - where c is the centre and here radius would be 2. The loop goes row by row and check every entry.

You must calculate every point of the circle having the center’s position and the radius and then draw it with GL_LINE_LOOP. here is the way I did it. I’m using TaoFramework and C#. First I create the vertices for the circle and store them in a list. The circle will always be created at the origin of the coordinate system.
