You can [look at](https://www.youtube.com/watch?v=R-lBsqAvSTA) a very similar “grow from seeds” effect. Its implementation is in [vtkImageGrowCutSegment.cxx](https://github.com/Slicer/Slicer/blob/08789e8f2224f89206b2d6a49d1d452d4e677994/Modules/Loadable/Segmentations/Logic/vtkImageGrowCutSegment.cxx).

@lassoan gave a great answer to this question with a how-to video [on the VTK discourse](https://discourse.vtk.org/t/how-to-segment-3d-volume/4906/2).
