DUTCH, a FORTRAN90 library which carries out tasks in computational geometry.
GEOMETRY, a FORTRAN90 library which performs geometric calculations in 2, 3 and N dimensional space.
GEOMPACK2, a more extensive FORTRAN90 library, from which GEOMPACK was extracted.
GEOMPACK3, a FORTRAN90 library which handles 3D geometric problems.
SPHERE_DELAUNAY, a FORTRAN90 program which computes and plots the Delaunay triangulation of points on the unit sphere.
TABLE_DELAUNAY, a FORTRAN90 program which reads a file of point coordinates in the TABLE format and writes out the Delaunay triangulation.
TRIANGULATION_TRIANGLE_NEIGHBORS, a FORTRAN90 program which reads data defining a triangulation, determines the neighboring triangles of each triangle, and writes that information to a file.
