You can always use the mathematical description of an ellipsoid and do some triangulation. Then you just render the triangles and you have a rendered ellipsoid.

I found an example of an equation you can use to get points on the ellipsoid surface by googling some.

My method works directly with OpenGL primitives, whereas it's a big step to go from a set of points to a rendered ellipsoid.
