Non-manifold triangles after running vtkBooleanOperationPolydataFilter

santosh Gaikwad
Hi All,

I am using vtkBooleanOperationPolydataFilter to boolean union of two polydata. Input objects are closed object and having water tight mesh.
In the result of vtkBooleanOperationPolydataFilter, I can see some non-manifold triangles at the intersection region of input objects. 
In following image you can see the non-manifold triangle with yellow color outline. The image is taken by zooming in to the triangle.

Does vtk haves any filter which will remove these non-manifold triangles ? or does  vtkBooleanOperationPolydataFilte haves any option which will not generate these triangles ?

Re: Non-manifold triangles after running vtkBooleanOperationPolydataFilter

Cory Quammen
This is most likely a bug in the vtkBooleanOperationPolyDataFilter. Can you post the image you referred to in your email showing the non-manifold triangle? Also, it would be helpful if you can post the polydata with which you are having problems.

Thanks,
Cory

Hi All,

I am using vtkBooleanOperationPolydataFilter to boolean union of two polydata. Input objects are closed object and having water tight mesh.
In the result of vtkBooleanOperationPolydataFilter, I can see some non-manifold triangles at the intersection region of input objects. 
In following image you can see the non-manifold triangle with yellow color outline. The image is taken by zooming in to the triangle.

Does vtk haves any filter which will remove these non-manifold triangles ? or does  vtkBooleanOperationPolydataFilte haves any option which will not generate these triangles ?

Re: Non-manifold triangles after running vtkBooleanOperationPolydataFilter

Dear Cory,

Attached image shows the non-manifold triangle in yellow color. I am
able to detect this using minimagics stl viewer.
Also I have attached a zip file which contains the input stls and
Boolean difference result. You can check the result in minimagics
software to detect non-manifold triangles.

Hope this will help you.

Regards
Santosh G.
