Detailed Description

Generate Enneper's surface.

vtkParametricEnneper generates Enneper's surface. Enneper's surface is a a self-intersecting minimal surface posessing constant negative Gaussian curvature

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.

Thanks:

Andrew Maclean a.maclean@cas.edu.au for creating and contributing the class.

Member Function Documentation

virtual const char* vtkParametricEnneper::GetClassName (   )  [virtual]

Reimplemented from vtkParametricFunction.

static int vtkParametricEnneper::IsTypeOf (  const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkParametricFunction.

virtual int vtkParametricEnneper::IsA (  const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkParametricFunction.

static vtkParametricEnneper* vtkParametricEnneper::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkParametricFunction.

void vtkParametricEnneper::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkParametricFunction.

static vtkParametricEnneper* vtkParametricEnneper::New (   )  [static]

Construct Enneper's surface with the following parameters: MinimumU = -2, MaximumU = 2, MinimumV = -2, MaximumV = 2, JoinU = 0, JoinV = 0, TwistU = 0, TwistV = 0, ClockwiseOrdering = 1, DerivativesAvailable = Reimplemented from vtkObject.

virtual int vtkParametricEnneper::GetDimension (   )  [inline, virtual]

Return the parametric dimension of the class. Implements vtkParametricFunction. Definition at line 54 of file vtkParametricEnneper.h.

virtual void vtkParametricEnneper::Evaluate (  double  uvw[3], double  Pt[3], double  Duvw[9] )  [virtual]

Enneper's surface. This function performs the mapping , returning it as Pt. It also returns the partial derivatives Du and Dv. . Then the normal is . Implements vtkParametricFunction.

virtual double vtkParametricEnneper::EvaluateScalar (  double  uvw[3], double  Pt[3], double  Duvw[9] )  [virtual]

Calculate a user defined scalar using one or all of uvw, Pt, Duvw. uv 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.
