[Paraview] Compute cell area

[Moreland, Kenneth]

John,

Thanks.  I already look into both of those filters.  Although both filters internally compute polygon area, I did not see a way to get the per-cell area (written out to a cell data array) from them.  When I run vtkIntegrateAttributes, I get a single value back that is the total area of all the cells.  I also did not see a clear way to get the data from vtkIntegrateFlowSurface.  Am I missing something?

I started writing this
https://svn.cscs.ch/vtkContrib/trunk/vtkCSCS/vtkCSCSCommon/vtkCellPropertiesFilter.cxx
header is also there.

But although it does the area of triangulted data ok, I never used it as I ended up using the vtkIntegrateAttributes (this does areas for all 2D cell types) filter and IntegrateFlowThroughSurface

Compute cell area Is there an easy way to compute the area of a 2D cell?
