I can't recall it from the name, neither find it with Google. Would you have a
link ? I would certainly enjoy seeing it again, as usual with your scenes :-)

Yes, it's heavily used in archaeology, generally only for the most important
pieces as it is very time consuming, and sometime challenging. You will probably
enjoy this speech of an archaeologist talking about their struggles to produce
models of obsidian artifacts:
I haven't mention it in my previous post but, any reflective or transparent
texture is also an immediate 'no go'. It completely confuses all current

I had plan to become a paleobiologist until I entered university where I've been
reoriented toward computer science. This has probably been a wise advice but I
always wonder what would have become that other me. So, I've been really happy
when I had the chance to work for archaeologists a few years ago.
