I have developed a MathLink delaunay triangulation implementation
and some associated code that solves some simple computational
geometry problems and allows general 3D surface plotting.
It is available through MathSource and is described below.

To have the new version sent to you, send the single-line message:

The item is also available through anonymous FTP and Gopher at [IP#] in the Enhancements/DiscreteMath

0205-041: Delaunay Triangulation and 3D Surface Construction Package
          (March 31, 1994)
          Author: Tom Wickham-Jones
          The package ExtendGraphics/Delaunay.m installs a MathLink program
          that contains code to carry out Delaunay triangulations in the
          plane. A number of applications of this functionality are also
          provided.  The package ExtendGraphics/SurfaceGraphics3D.m contains
          code to draw surfaces in three-dimensions from organised and
          random data sets.

          The binary executable "delaunay" must be built for these functions
          to work.  This can be done from the file, with the
          command mcc -o delaunay
