<DIV><FONT size=2>Dear Mr.Liu,</FONT></DIV>
<DIV><FONT size=2>Thanks a lot for your advice.</FONT></DIV>
<DIV><FONT size=2>Frankly, I am not familiar with 3D graphics. I just know
that </FONT><FONT face=Arial size=3><FONT size=2>vtkSurfaceReconstructionFilter
can</FONT> <FONT size=2>produce the surface of a 3D object according to the
manual document of VTK. However, I don't understand how this vtk class works
and how to get the number of volumes included in the meshed
3D object. Could you tell me which vtk filter is able to mesh the
3D object using those unorganized points in 3D space and provide
information of volume elements? Thank you very much.</FONT></FONT></DIV>

<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>I do not know if the <FONT
size=3>vtkSurfaceReconstructionFilter can help, but first mesh the 3D
object and then compute all the volumes of the elements in the mesh will help
you solve this question. Hope it help.</FONT></FONT></DIV>
