[Paraview] Calculating Volumes

[Charles Law]

Ezequiel,

Although VTK has a filter (vtkMassProperties) that calculates the volume of 
a closed surface, it has not been integrated into ParaView.  You could save 
out the data and use a VTK script to compute the volume.

Although it will not probably help you, you can get an estimate of the 
volume if your structured data set is a uniform grid (image).  Just use 
threshold instead of contour and look at the number of cells on the 
information page.

Charles.
