Drawing an ellipse in THREE.js

I am trying to draw a three-dimensional ellipse with THREE.js.

I noticed in the dev version (r50-dev), EllipseCurve( extras / core / Curve.js ) and path.ellipse( extras / core / Path.js ).

Unfortunately, I am new to THREE.js, and although I can do basic things, I have not been able to find a Curve tutorial, much less a tutorial on the still developing EllipseCurve.

I also understand that I can do this with a few Bezier curves.

Any pointers would be greatly appreciated!
