Why is there no circle or ellipse primitive in OpenGL?

Question

Circles are one of the basics geometric entities. Yet there is no primitives defined in OpenGL for this, like lines or polygons. Why so? It\'s a little annoying to include custo

Answer 1

You could always use gluSphere (if a three-dimensional shape is what you're looking for).

If you want to draw a two-dimensional circle you're stuck with custom methods. I'd go with a triangle fan.

The primitives are called primitives for a reason :)
