I think this was the same camera and software combination that I recently
saw but it was only $5000.
What is the relation to Stereo - simple, once you have a 3d model in the
computer you can now animate and use multiple cameras to generate stereo
images - this is what Boris does when he isn't working with his nodes and
real cameras.
In the little description I saw on this camera it was any object could be
photographed and converted. The grid like you say allows the software to
calculate the points in space and if you do a sequence of images/points
consistently you can get the full model. The choice of faces I think comes
from trying to build realistic faces with geometric shapes unless you have
specific software for the task this isn't all that easy to do with CAD like
software. But the system shouldn't be limited to this unless that was their
only intended market.
