This code is described in "Computational Geometry in C" (Second Edition),

Chapter 4. It is not written to be comprehensible without the

explanation in that book.



Input: 3n integer coordinates for the points.

Output: the 3D convex hull, in postscr ipt with embedded comments

showing the vertices and faces.



Compile: gcc -o chull chull.c (or simply: make)-This code is described in "Computational Geometry in C" (Second Edition),
