However, "true displacement mapping" as used in practice, involves tessellating
the primitive and displacing the resultant mesh.
The way I understand it, performing non-uniform transformations (including
displacement mapping) on a mathematical primitive would require finding the
intersection of the primitive and a curved ray - often impossible for all
practical purposes.

I'll bet Ron Parker could code it. Ron Parker can code anything if
he sets his mind to it.

No, no, that wasn't to say that I can't do the work, just that my role of late
has been more that of the guy who plants seeds in the minds of people who have
time to do stuff.
Besides, it was a Dilbert quote.
