I would appreciate some references to - or a quick discussion of
Barycentric coordinates.  I think I want to use them to answer the
the following problems:

1) Given a set of n points (in 2 or 3 space),
   decide whether an arbitrary given point is interior to the convex hull of
   the n points.

2) Given a set of n points, find which edge of their convex hull is closest
   to an arbitrary given point.

Thanks
