[vtkusers] Segmentation fault with vtkBooleanOperationPolyDataFilter using 2 cylinders [HELP]

[Cory Quammen]

Hi Drak,

Two things:

1). You might want to try the master branch in VTK's git repository. There
have been some recent changes that might fix your problem.

2). Would it be possible to post a stack trace where your program crashes?
Or report radius values that lead to the crash?

Thanks,
Cory
