[vtkusers] Warning from vtkDecimate

[Pingkun]

Dear all,

I got polydata using vtkMarchingCubes filter from volumetric data and then tried to decimate the polydata with vtkDecimate. It works but gives out many warnings as follows.

Warning: In D:\Src\VTK\Patented\vtkDecimate.cxx, line 773
vtkDecimate (025327E0): Non-manifold geometry encountered

I searched vtkusers mailing list but can not get solution. Anybody help? Thanks!

Rgds,
Pingkun
