Generate a supertoroid.
vtkParametricSuperToroid generates a supertoroid. Essentially a supertoroid is a torus with the sine and cosine terms raised to a power. A supertoroid is a versatile primitive that is controlled by four parameters r0, r1, n1 and n2. r0, r1 determine the type of torus whilst the value of n1 determines the shape of the torus ring and n2 determines the shape of the cross section of the ring. It is the different values of these powers which give rise to a family of 3D shapes that are all basically toroidal in shape.
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.

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.
