Hi, How can I draw an Ellipse using openGL ES
A:
Draw a bunch of line segments around the circumference.
Also note that your system may not support anti-aliased lines (the iPhone doesn't). There's a nice article on drawing antialiased lines here. You can do something similar to draw the line segments (though you don't need the end-caps, so it's a bit simpler).
Another solution to anti-aliasing that requires more polygons is here.
