Generate an ellipsoid.
vtkParametricEllipsoid generates an ellipsoid. If all the radii are the same, we have a sphere. An oblate spheroid occurs if RadiusX = RadiusY > RadiusZ. Here the Z-axis forms the symmetry axis. To a first approximation, this is the shape of the earth. A prolate spheroid occurs if RadiusX = RadiusY < RadiusZ.
For further information about this surface, please consult the technical description "Parametric surfaces" in http://www.vtk.org/documents.php in the "VTK Technical Documents" section in the VTk.org web pages.

An ellipsoid. This function performs the mapping , returning it as Pt. It also returns the partial derivatives Du and Dv.
. Then the normal is

virtual |
Calculate a user defined scalar using one or all of uvw, Pt, Duvw. uvw are the parameters with Pt being the the cartesian point, Duvw are the derivatives of this point with respect to u, v and w. Pt, Duvw are obtained from Evaluate(). This function is only called if the ScalarMode has the value vtkParametricFunctionSource::SCALAR_FUNCTION_DEFINED If the user does not need to calculate a scalar, then the instantiated function should return zero.
Implements vtkParametricFunction.
