Detailed Description

TTK processing package for mesh preprocessing before using TopoCluster.

The CompactTriangulationPreconditioning class provides methods to compute the indexing for each vertex and then used for TopoCluster data structure.

Date: May 2021.

Given a simplicial mesh, this class uses PR star octree to divide it into multiple clusters, and the cluster of each vertex is written as a new scalar field.
