int GetDimension() override
Return the parametric dimension of the class.
virtual double EvaluateScalar(double uvw[3], double Pt[3], double Duvw[9])=0
Calculate a user defined scalar using one or all of uvw, Pt, Duvw.
virtual void Evaluate(double uvw[3], double Pt[3], double Duvw[9])=0
Performs the mapping $f(uvw)->(Pt,Duvw)$f.
Generate Steiner's Roman Surface.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
abstract interface for parametric functions
a simple class to control print indentation
