Is there any function in opengl such as GL_lINES or GL_TRIANGLES which allows you to draw a circle of radius r, centre(x,y,z). If not, what is the easiest way to draw circles in opengl.
Thanks a lot.

no, there’s nothing like GL_CIRCLE in OpenGL

but take a look here
i think there’s been another thread on circles some days ago (try SEARCH to find them)

good luck!

try this too
