Dear Dennis, I have had demonstration session with the Artec MHT <http://www.artec3d.com/hardware/artec-mh/> (discontinued) from a research group in Spain. It is quite good with human faces. Able to scan dark faces (surfaces), glasses and facial hair as well. The person can open their eyes as well (if they don't mind constant LED flashes). However with hair and glasses, the glasses tend to "protrude" on the face. Scanning is quite quick. I think the portability of the Artec is a good feature as not all items can be placed on a rotating platform for scanning like the NextEngine. With the artec, you need to move around/have a rotating table or chair and scan it yourself. I assume the Spider is better than the MHT.
Another scanner is the Polhemus FastSCAN Cobra <http://polhemus.com/scanning-digitizing/fastscan-cobra-ci/>. I am not sure how this performs in relation to the Artec. I had use the Polhemus Scorpion. It is not as fast as the Artec, unable to scan dark. transluscent objects (without some sort of powder application). It is portable, but slightly bigger compared to the Artec. Metal objects are a problem with the Scorpion. If you do manage to find a scanner, would you mind sharing with us which model is best? Especially in the high-resolution and portable area.
