The C++ source code for the model-to-model distance module is [here](https://github.com/NIRALUser/3DMetricTools/tree/master/ModelToModelDistance).

It uses the vtkDistancePolyDataFilter which also has a Python wrapper. I have a Python module that uses this filter [here](https://github.com/SlicerMorph/SlicerMorph/blob/4e7fcdf0a9e035cb66539ba140b8ba32a7413da8/MeshDistanceMeasurement/MeshDistanceMeasurement.py#L281) which may help as an example.
