[Insight-users] Re: VTK polydata

[Luis Ibanez]

Hi Alam,

Please read the desciption of the VTK file format in the
VTK Users Guide, page 287.

The problem in your file is that in your POLYGONS section
you are numbering the points from 1 to 8267. You should
be using numbers from 0 to 8266.



E.g. the first cell should be

     POLYGONS 16374 65496
     3 0 2 1

and not the current

      POLYGONS 16374 65496
      3 1 3 2



   Regards,


       Luis
