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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkParametricFunction.

overridevirtual

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 vtkObjectBase.

◆ New()

static vtkParametricBour * vtkParametricBour::New ( )

static

Construct Bour's minimal surface with the following parameters: (MinimumU, MaximumU) = (0., 1.), (MinimumV, MaximumV) = (0., 4.

*pi), JoinU = 0, JoinV = 0, TwistU = 0, TwistV = 0; ClockwiseOrdering = 0, DerivativesAvailable = 1,

◆ GetDimension()

int vtkParametricBour::GetDimension ( )

inlineoverridevirtual

Return the parametric dimension of the class.

Implements vtkParametricFunction.

◆ Evaluate()

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

overridevirtual

Bour's minimal surface.

This function performs the mapping $f(u,v) \rightarrow (x,y,x)$ , returning it as Pt. It also returns the partial derivatives Du and Dv. $Pt = (x, y, z), D_u\vec{f} = (dx/du, dy/du, dz/du), D_v\vec{f} = (dx/dv, dy/dv, dz/dv)$ . Then the normal is $N = D_u\vec{f} \times D_v\vec{f}$ .

Implements vtkParametricFunction.

◆ EvaluateScalar()

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

overridevirtual

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

This method simply returns 0.

Implements vtkParametricFunction.
