RE: Q: 3D convex hull?

As far as I know, there is no package for ConvexHull in more than two =
dimensions.
Have a look at
http://www.geom.umn.edu/software/qhull/
which gives C sources that you might use after defining a mathlink =
external function
If you are interested, I have another algorithm in c++, which works in =
any dimension, let me know.

Anyone know of a Mma package that might have something for computing the =

tesselation of a convex hull 3D points? I see the one in=20
DiscreteMath`ComputationalGeometry but I need it for 3D.

MathSource came up with "Vertex Enumeration Package for Convex Polytopes =
and=20
Arrangements" when I searched for "convex hull" but I have no idea what =
this=20
package is (I'm downloading it anyway and will take a look).

Thanks in advance,

- Gareth
