Detailed Description

Implicit function that computes the distance from a point x to the nearest point p on an input vtkPolyData. The sign of the function is set to the sign of the dot product between the angle-weighted pseudonormal at the nearest surface point and the vector x - p. Points interior to the geometry have a negative distance, points on the exterior have a positive distance, and points on the input vtkPolyData have a distance of zero. The gradient of the function is the angle-weighted pseudonormal at the nearest point.

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 vtkImplicitFunction.

void vtkImplicitPolyDataDistance::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 vtkImplicitFunction.

unsigned long vtkImplicitPolyDataDistance::GetMTime ( )

virtual

Return the MTime also considering the Input dependency.

Reimplemented from vtkImplicitFunction.

double vtkImplicitPolyDataDistance::EvaluateFunction ( double x[3] )

virtual

Evaluate plane equation of nearest triangle to point x[3].

Implements vtkImplicitFunction.

void vtkImplicitPolyDataDistance::EvaluateGradient	(	double	x[3],
		double	g[3]
	)

virtual

Evaluate function gradient of nearest triangle to point x[3].

Implements vtkImplicitFunction.

double vtkImplicitPolyDataDistance::EvaluateFunctionAndGetClosestPoint	(	double	x[3],
		double	closestPoint[3]
	)

Evaluate plane equation of nearest triangle to point x[3] and provides closest point on an input vtkPolyData.

void vtkImplicitPolyDataDistance::SetInput ( vtkPolyData * input )

Set the input vtkPolyData used for the implicit function evaluation. Passes input through an internal instance of vtkTriangleFilter to remove vertices and lines, leaving only triangular polygons for evaluation as implicit planes.

virtual void vtkImplicitPolyDataDistance::SetNoValue ( double )

virtual

Set/get the function value to use if no input vtkPolyData specified.

virtual double vtkImplicitPolyDataDistance::GetNoValue ( )
