I'm not sure _exactly_ what your end goal is (perhaps link to an example), but I
do believe that we established that a scaled sphere is an ellipsoid, so you
could just use that, or a blob {} object.

Aside from that, there are any number of primitives that can be used to render
ellipsoidal shapes.  Isosurfaces, polynomials, parametrics, spheres, . . .

I need to better understand your specific needs in order to offer better advice.
