<p class="MsoNormal">Dear VTK and ITK users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried to calculate polydata volume
through vtkMassProperties. Firstly, the polydata was generated
from a set of 3D points. Then I applied
vtkSurfaceReconstructionFilter to generate a surface. And then
a contour was generated by vtkContourFilter. After several
other steps, I got the volume by vtkMassProperties.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem is:<o:p></o:p></p>

my code is proper to calculate polydata volume?<o:p></o:p></p>

style="">2.<span style="font: 7pt "Times New

change the SetValue(0, 10) of vtkContourFilter to some value
else, for example, SetValue(0, 20), the calculated volumes
under the two conditions are very different. What value is
proper to calculate volume?<o:p></o:p></p>
