Yeah, the full scan things are cool, but the problem is all that info, all that massive info, is not easily converted clean surface data. (and then 'solid" data) Some improvements have been made recently ...but still lacking, IMO.
I'm not saying it's useless (or close). Just that for a sculptor, I would suggest waiting for this technology to become more mature before spending too much time fussing with it . .. chasing what you expect it
should do for ya.
oh, and the above was done with a MicroScribe (arm) various engineering measuring tools, SolidWorks (CAD). engine and parts borrowed from John Walkers Workshop.
