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.
