[vtkusers] volume error calculation

[Marcel Weiss]

yes, vtkMassProperty should solve this problem

subtracting the mass covered by the inner surface from the mass covered by the outer surface results in the mass between the two surfaces. (as long as the surfaces do not intersect.)

btw: are we talking about cortical surfaces?

what is a volume between two surfaces?

yes, pretty much, vtk can help you (was it something called mass 
properties?)
