Currently, input for TetGen is created by appending closed surface representation of each segment into a single polydata. This only works well when segment boundaries don't intersect.

vtkCleanPolydataFilter might be enough to remove duplicate points/triangles, but most probably some more sophisticated pre-processing would be necessary (maybe something similar to what is done in joint smoothing segment editor effect).
