Detailed Description

TTK processing package for the topological simplification of scalar data.

Author: Julien Tierny julie.nosp@m.n.ti.nosp@m.erny@.nosp@m.lip6.nosp@m..fr; Guillaume Favelier guill.nosp@m.aume.nosp@m..fave.nosp@m.lier.nosp@m.@lip6.nosp@m..fr

Date: February 2016

Given an input scalar field and a list of critical points to remove, this class minimally edits the scalar field such that the listed critical points disappear. This procedure is useful to speedup subsequent topological data analysis when outlier critical points can be easily identified. It is also useful for data simplification.
