Yeah, I sure am, too. I did some intense net searching about this a
couple of years ago, and the big stumbling block was photo =>
3D conversion. I found a couple of companies that had software
that could take several photos and convert to a point cloud. One of
them had a great bust of a person. I inquired how they did that, and
they apologetically told me that it took 8 hours of work by an expert
to identify the same spot on several photos to the software, over and over,
so the software could match up the 3-D coordinates. In other words, it
really doesn't work well with faces, but does great on buildings with
sharp corners. I don't know if the software has improved any since
then. Given a point cloud, I think I could even figure out how to do
the rest myself.

There seems to be some advances in the 3-D scanning machines, too,
but they are still REALLY expensive.
