Detailed Description

TTK VTK-filter that computes a Rips complex.

Author: Pierre Guillou pierr.nosp@m.e.gu.nosp@m.illou.nosp@m.@lip.nosp@m.6.fr

Date: January 2022

Parameters

Input	Input table (vtkTable)
Output	Triangulation (vtkUnstructuredGrid)

TTK VTK-filter that takes a matrix (vtkTable) as input and computes a Rips complex from it to generate an explicit triangulation.

See also: ttk::Triangulation; ttkRipsComplex.cpp for a usage example.
