If you check the doxygen for vtkTriangle, there should be a member function that returns the area of a specific triangle. Otherwise, the area of a triangle is calculated as follows: // 2 // / \ v1 = (pt1-pt0) // / \ v2 = (pt2-pt0) // 0-----1 area = 0.5*mag( v1 x v2 ) You can write a quick script that does this for each face. If I get time later today, I can supply a script as well.
