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.

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.

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

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).
