Hi all
I'm trying to use the Visible woman data to make my own visible woman
following the instructions of
http://www.crd.ge.com/esl/cgsp/projects/makevw/
<http://www.crd.ge.com/esl/cgsp/projects/makevw/> 
I used the same parameters as in the scrpits. In fact,  I'm just translating
from tcl to visula C++.
I have the following message "non-manifold geometry encoutred" and this
comes from vtkDecimate.
Did anyone already try it? I need your help.
Lydia
