Detailed Description

compute an approximation of the volume contour signature (evolution of the volume of the input tet-mesh along an arc of the Reeb graph).

The filter takes a vtkUnstructuredGrid 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 vtkUnstructuredGrid, see SetFieldId (default: 0). The filter will abort if this field does not exist.

The filter outputs a vtkTable with the volume 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.

static int vtkVolumeContourSpectrumFilter::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.

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.
