[vtkusers] vtkBooleanOperationPolyDataFilter crashes while trying to intersect 2 vtkTubeFilter outputs

[Andras Lasso]

I think Boolean mesh operations are the only filters in VTK that are broken - randomly produce somewhat incorrect results and sometimes cause crash. There were attempts in the past to fix them, but the task proved to be too difficult for everybody.

If you clean the inputs and/or slightly dislocate them then you might get correct results. If you need a VTK-based solution that works for any input mesh then you can convert meshes to binary images, perform the Boolean operation on the images, and convert the result to mesh.

Thanks for answering my question.
I am already using vtkTriangleFilter and vtkButterflySubdivisionFilter to
get fine triangle cells.
Unfortunately, it didn't help.
