Collision Detection Capabilities in 3D Slicer

Yes, this is the crux of the problem, in that I do not know how to extract the transforms from the model nodes so that I can pass them into the collision detection filter.

You can get transform using transformNode.GetMatrixTransformToParent(transformMatrix). See many examples in the Slicer script repository.

I have tried following the example in how the transforms were set, but I still have Slicer 4.13 crashing on me upon the GetNumberOfContacts() function call.

I experienced the same crash recently. I have filed a bug report:
