That's correct. They want you to pay for the surface-surface intersection
algorithms. I would be highly interested in working on surface-surface
intersection algorithms for BRLCAD, but all of my implementations have
sucked immensely. I think the real trick is doing a survey of the different
approaches, finding someone who has done it before and picking their brain,
then outlining the full chain of steps. Otherwise we will end up spinning
our wheels.
