strips and joining them along their boundaries, this is the so called
"Figure-8 Klein Bottle"
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.
.SECTION Thanks Andrew Maclean a.maclean@cas.edu.au for creating and contributing the class.
To create an instance of class vtkParametricFigure8Klein, simply invoke its constructor as follows
obj = vtkParametricFigure8Klein
obj
is an instance of the vtkParametricFigure8Klein class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkParametricFigure8Klein = obj.NewInstance ()
vtkParametricFigure8Klein = obj.SafeDownCast (vtkObject o)
obj.SetRadius (double )
- Set/Get the radius of the bottle.
double = obj.GetRadius ()
- Set/Get the radius of the bottle.
double = obj.EvaluateScalar (double uvw[3], double Pt[3], double Duvw[9])
- 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.
