Hi, I made a cool spinning triangle with OpenGL and I want to make it into a circle or square. How?

to draw a square, use glBegin( GL_QUADS ) instead of glBegin( GL_TRIANGLES ). as for the circle, there is no explicit support for circles in openGL

Use a quad to make it a square, but you'll need quadrics to draw a circle. Look at nehe's tutorial on quadrics, and use a disc or flat cylindar.
