QHULL/VORONOI question [message #61321]

I have 3D data (particle positions) and i'm trying to obtain voronoi
polyhedra using QHULL. I need to calculate
cell volumes and mean voronoi volume of the system. However, the
output of voronoi using QHULL is very confusing (specifically, the
connectivity list). I understand the array which lists the vertices.
However, the connectivity list a
simple 1-D array. I have no way of telling which vertices constitute a
specific voronoi cell. In MATLAB the output of qhull is slightly more
clear where the connectivity list is a 4 or 5 x n array which lists
all the vertices making up
a voronoi cell, only it unfortunately includes unbounded points. So my
question is, am I interpreting the results of QHULL in IDL wrong? Is
there a way for me to match the connectivity list with the vertices
QHULL gives
me in order to calculate a cell volume? Thanks for any input/advice!
