Sorry to be such a pain about this...

If the member variable IS a smart pointer, then does it do the
register/unregister automatically? Is it recommended to have member
variables as smart pointers or not? If you DO make the member variable a
smart pointer, you must break the "don't include any headers but your
superclass" rule. Is that allowed in this case?

I switched to
vtkSetObjectMacro(Ray, vtkRay);
in an attempt to have it do the register/unregister automatically, but it
simply segfaults when I call SetRay.

The updated and simplified files are here:

Thanks,
