Detailed Description

generate points on isosurface

vtkEdgePoints is a filter that takes as input any dataset and generates for output a set of points that lie on an isosurface. The points are created by interpolation along cells edges whose end-points are below and above the contour value.

Warning:: vtkEdgePoints can be considered a "poor man's" dividing cubes algorithm (see vtkDividingCubes). Points are generated only on the edges of cells, not in the interior, and at lower density than dividing cubes. However, it is more general than dividing cubes since it treats any type of dataset.

Member Function Documentation

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkEdgePoints::IsTypeOf ( const char * name ) [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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkEdgePoints::IsA ( const char * name ) [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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

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

Reimplemented from vtkPolyDataAlgorithm.

void vtkEdgePoints::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 vtkPolyDataAlgorithm.

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

Construct object with contour value of 0.0.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkEdgePoints::SetValue ( double ) [virtual]

Set/get the contour value.

virtual double vtkEdgePoints::GetValue ( ) [virtual]

Set/get the contour value.

virtual int vtkEdgePoints::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, virtual]`

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkEdgePoints::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)			`[protected, virtual]`

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPolyDataAlgorithm.
