triangle_io, a Fortran90 code which can read or write some simple versions of some of the files used by Jonathan Shewchuk's triangle() program.

triangle_io is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version.
fem_to_triangle, a Fortran90 code which reads FEM files defining a 2D mesh of triangles, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding pair of node and element files for use by Jonathan Shewchuk's triangle() program.
showme, a C code which can display the POLY files uses as input to triangle(), and the output files that define meshes and other objects.
triangle, a C code which computes Voronoi diagrams and Delaunay triangulations, and creates and manipulates files that can be displayed by showme().
triangle_display, a MATLAB code which displays the nodes and elements of a triangulation on the MATLAB graphics screen, assuming the data has been stored in NODE and ELE files by the TRIANGLE program.
triangle_files, a data directory of examples of files used by the triangle() and showme() programs.
triangle_to_fem, a Fortran90 code which reads the NODE and ELE files created by triangle() to describe a triangular mesh, and writes a corresponding pair of node and element files in the 2D FEM format.
triangle_to_xml, a Fortran90 code which reads the NODE and ELE files created by triangle() to describe a triangular mesh in 2D, and writes out a corresponding XML mesh file for use by DOLFIN or FENICS.
