"""Qhull computes the convex hull, Delaunay triangulation, Voronoi

diagram, halfspace intersection about a point, furt hest-site

|
Delaunay triangulation, and furthest-site Voronoi diagram. The
|
|
source code runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull
|
|
implements the Quickhull algorithm for computing the convex
|
|
hull. It handles roundoff errors from floating point
|
|
arithmetic. It computes volumes, surface areas, and
|
|
approximations to the convex hull.

Qhull does not support triangulation of non-convex surfaces,
|
|
mesh generation of non-convex objects, medium-sized inputs in
|
|
9-D and higher, alpha shapes, weighted Voronoi diagrams,
|
|
Voronoi volumes, or constrained Delaunay triangulations."""
