One would assume that you've checked out FM's pages:

It looks like it's analagous to texture vs inside_texture in that it chooses one
texture or another. With this, it's not what "side" it on, it's whether or not
the point is any part of the object or not at all.

So presumably a[nother] good test scene would be a small object inside a
transmissive sphere - with the sphere representing the outside environment of
the object, and the object the inside.

[As with the rest of life] I find the pictures very helpful in understanding
what's going on.  When it's all text and I have to sound it out, people think
I'm talking to myself in some made up language...
