Detailed Description

abstract class for custom Reeb graph simplification metric design.

This class makes it possible to design customized simplification metric evaluation algorithms, enabling the user to control the definition of what should be considered as noise or signal in the topological filtering process.

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 vtkObjectBase.

◆ PrintSelf()

void vtkReebGraphSimplificationMetric::PrintSelf ( ostream &  os,

overridevirtual

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 vtkObject.

◆ SetLowerBound()

virtual void vtkReebGraphSimplificationMetric::SetLowerBound ( double  )
virtual

Set the lowest possible value for the custom metric space.

This value can be set prior to launching the Reeb graph simplification and then used inside the ComputeMetric call to make sure the returned value of ComputeMetric call is indeed between 0 and 1.

◆ GetLowerBound()

virtual double vtkReebGraphSimplificationMetric::GetLowerBound ( )

◆ SetUpperBound()

virtual void vtkReebGraphSimplificationMetric::SetUpperBound ( double  )
virtual

Set the highest possible value for the custom metric space.

This value can be set prior to launching the Reeb graph simplification and then used inside the ComputeMetric call to make sure the returned value of ComputeMetric call is indeed between 0 and 1.

virtual double vtkReebGraphSimplificationMetric::ComputeMetric ( vtkDataSet mesh,
vtkDataArray field,
vtkIdType  startCriticalPoint,
vtkAbstractArray vertexList,
vtkIdType  endCriticalPoint 
)
virtual

Function to implement in your simplification metric algorithm.

Given the input mesh and the Ids of the vertices living on the Reeb graph arc to consider for removal, you should return a value between 0 and 1 (the smallest the more likely the arc will be removed, depending on the user-defined simplification threshold).
