Which portion of an ellipsoid do you need ?
If it's a 2D surface, intersection with a couple of parallele plane
should be fine.
Or direct usage of an ellipse.
If it's part of the 3D surface, it obviously depend on which part of
the ellipsoid you want.
CSG is one way.
Parametric another.
And isosurface also... as well as meshes, smooth triangles and so on.
