[vtkusers] How to prevent holes resulted from decimation?

[Ben Baojun Li]

Hello everyone,

I have a problem with the decimation. Since I have to use an extensive
decimation (.99 reduction ratio) following the marching cubes, there
are many holes on final rendered object surfaces. If I set a smaller
reduction ratio (e.g. 0.5), holes dissapeared, but the extreme large
amount of triangles are also a problem. I learned from one of VTK
examples that I should turn the 'PreserveTopology' feature on. So I did
it, but results are still not satisfying.

I don't know what's wrong with my code, is there any other features I
should turn that on, or something else?

Thanks a lot!

Ben
