Web References to Barycentric Coordinates
Supplement for Math 331
February 1, 2002
The following is a short list of web references on barycentric
coordinates found quickly with the search engine
Google.
 Ken Joy's Online Computer Graphic Notes on
Barycentric Coordinates
 Eric Weisstein's
World
of Mathematics
 Weissstein's World of Mathematics at Wolfram is often a good place
to look for mathematical information on the web.
 Alexander Bogomolny's
Barycentric
Coordinates
 With a reference to Ceva's Theorem.
 Paul Wiu has a
formal article.
 An article presented in PDF format, not HTML, entitled
The Uses of Homogeneous Barycentric Coordinates in Plane Euclidean
Geometry (There appear to be
rendering glitches in my PDF reader.)
 John Conway's extensive comment on
Trilinear vs. Barycentric
Coordinates
 Part of a rather advanced discussion at The Math Forum. Conway
compares several different ways of using the vertices of a given
triangle to spawn a coordinate system in the plane.
