After I posted my hasty response, I realized that even if it WAS a location,
it's a torus, and that would be bad too   :D

<1, 0, 0>*(MajorRadius) would be a good vector that would intersect the torus if
the test ray originates at the origin.

I would presume that if that inside_vector is part of the mesh definition, then
when the torus gets rotated, the inside_vector gets modified in the same
fashion.

It's always these little details.  ;)
