Detailed Description

Subdivise a triangulation according to triangle barycenter.

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

Date: July 2019

BarycentricSubdivision generates a new, finer triangulation from an input triangulation. Every triangle is divided in six new triangles using the 3 edges middles and the triangle barycenter.

Scalar data on vertices (point data) with continuous values (float/double) can be interpolated on the new triangulation. Scalar data on input triangles can be replicated on the new triangles.

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