Triangle - A 2D Quality Mesh Generator and Delaunay Triangulator

This is a port of Jonathan Shewchuk's Triangle library to R. From his description: "Triangle generates exact Delaunay triangulations, constrained Delaunay triangulations, conforming Delaunay triangulations, Voronoi diagrams, and high-quality triangular meshes. The latter can be generated with no small or large angles, and are thus suitable for finite element analysis."

CHANGES IN VERSION 1.6-0.6 - Released 2014-08-08

LICENCE CHANGE

  • The licence has changed from a combination of GPL-2 (for R code) and Schewchuk's Triangle licence to CC BY-NC-SA 4.0. This change was prompted by the CRAN maintainers and is due to Schewchuk's licence not being a FOSS licence.

BUG FIXES

  • Fix for Issue #2358: RTriangle_1.6-0.5.tar.gz does not pass 'R CMD check' on Windows (https://r-forge.r-project.org/tracker/index.php?func=detail&aid=2358&group_id=1077&atid=4271) Thanks to Uwe Ligges for alerting me to this.
