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.
