Detailed Description

compute an approximation of the area contour signature (evolution of the area of the input surface along an arc of the Reeb graph).

The filter takes a vtkPolyData as an input (port 0), along with a vtkReebGraph (port 1). The Reeb graph arc to consider can be specified with SetArcId() (default: 0). The number of (evenly distributed) samples of the signature can be defined with SetNumberOfSamples() (default value: 100). The filter will first try to pull as a scalar field the vtkDataArray with Id 'FieldId' of the vtkPolyData, see SetFieldId (default: 0). The filter will abort if this field does not exist.

The filter outputs a vtkTable with the area contour signature approximation, each sample being evenly distributed in the function span of the arc.

This filter is a typical example for designing your own contour signature filter (with customized metrics). It also shows typical vtkReebGraph traversals.

Member Function Documentation

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

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkDataObjectAlgorithm.

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

Reimplemented from vtkDataObjectAlgorithm.

static int vtkAreaContourSpectrumFilter::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 vtkDataObjectAlgorithm.

virtual int vtkAreaContourSpectrumFilter::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 vtkDataObjectAlgorithm.

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

Reimplemented from vtkDataObjectAlgorithm.

void vtkAreaContourSpectrumFilter::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 vtkDataObjectAlgorithm.
