- Many people responded. Thanks to everybody!

- - Reading now the textbook "Computational Geometry, an Introduction",
- by Franco P. Preparata and Michael Ian Shamos, 1985, Springer-Verlag.
-
- - Made an "anonymous ftp" to netlib@research.att.com , subdirectory "acm",
- and got algorithm 626 from the ACM Transactions on Mathematical Software,
- looked up accompanying articles in the library (but didn't save them).
-
- - Made another "anonymous ftp" to netlib@research.att.com ,
- and got everything from the "voronoi" triangulation subdirectory.

-
- Nobody heard of it, of course: the beast is called a Delaunay triangulation.
- (Well, allow me some nitpicking: it's also not "delaney", "Delauney", ...)
-
- Next question:
- || ----------------------------------------------------------------------
- || Are there any generalizations (and computer programs) for the 3-D case ?

-
- Please forgive that I don't read "sci.math" anymore. E-mail preferred.
