[GRASS-user] strange output from v.voronoi

[Dylan Beaudette]

Hi,

This morning I noticed very odd output from v.voronoi, specifically on "split" 
between adjacent points was missing and the output messages contained the 
following:

Number of nodes: 22
Number of primitives: 27
Number of points: 0
Number of lines: 0
Number of boundaries: 20
Number of centroids: 7
Number of areas: 6
Number of isles: 1
Number of duplicate centroids: 1

The resulting voronoi polygons are attached.

Here are some details on the vector:

Number of points:       127

type       count        min        max
point        127          1        127
line           0          0          0
boundary       0          0          0
centroid       0          0          0
area           0          0          0
face           0          0          0
kernel         0          0          0
all          127          1        127

Here is the version information:
GRASS 6.5.svn (2010) 

 ./configure  --with-tcltk-includes=/usr/include/tcl8.4 --with-postgres --without-odbc --with-mysql --with-mysql-includes=/usr/include/mysql/ --with-freetype --with-freetype-includes=/usr/include/freetype2 --with-readline --with-cxx --enable-largefile --with-postgres-includes=/usr/local/pgsql/include/ --with-postgres-libs=/usr/local/pgsql/lib/ --with-sqlite --with-python --with-proj-share=/usr/local/share/proj/ --with-cairo

Could it be that the bad output is caused by some fundamental problem with the 
input point vector?

Cheers,
Dylan
