[vtkusers] python - volume/surface area calculations

[Alyassin, Abdalmajeid M (CRD)]

For calculating the surface area you should be ok (I have used it in tcl/tk with no problems).
However, for measuring the volume you need to make sure the surface is closed otherwise you may under
or over estimate the volume.

Hope this helps.

Subject: [vtkusers] python - volume/surface area calculations


Can someone give me a tip on how to take a polygon data set - say like
spleen.color.vtk and do surface area and volume calculations on the data
set.  I am working in python (idle / mayavi) and have tried various
approaches using vtkTriangleFilter and vtkMassProperties but I have not
been succesful.  Is there a code fragment somewhere that can point the way?

Thanks,

Rod
