Really? To prove your point, I'd like to see you accurately model and texture a person's face. Please make it identical to the original person (within a few thousandths of an inch), and do in under 15 minutes.

Use the woman in this video as a reference.

Awaiting your response...

Notice they say "up to 80 microns" - that's because you usually don't get the theoretical maximum accuracy with the ZScanner. NextEngine's scanner consistently delivers 0.005" accuracy, or about 127 microns.

NextEngine's 3D scanner has higher resolution, captures full color, and is under $3k. The system comes with software powered by RapidForm (costs about $20k standalone - google it), and a robotic positioner. No size limit.

Regarding the value of the NextEngine ScanStudio software: It's based on RapidForm's XOR libraries for automatic genetic alignment, volumetric merging, global remeshing (retopologizing), hole-filling, and polishing. These algorithms are widely recognized as the best in the world. You can buy RapidForm's XOR product without the NextEngine scanner, but it will cost you over $20,000 (they come included with the NextEngine Scanner for under $3k).

Lt. Massa: The HD scanner uses a different CMOS setup with twice the resolution of the original model. The new version also uses a color wheel to sample up to 7 different color channels for better color accuracy. Oh, and we spent a year and a half developing new software to support the 4x increase in data throughput, justifying the $500 price increase.

As far as ease of use, I did this scan in an afternoon: http://www.youtube.com/watch?v=BCwu8TSurdQ&fmt=18

(And no, you don't have to manually "mesh" together scans. The software does it automatically. I'm guessing Lt. Massa works for one of our competitors, or is just an idiot.)

Actually, use of the automatic positioner is not required. Even if your target is much bigger than the scanner's field of view, you can always do multiple "pans", then stitch them together in software. The software that comes with the scanner provides an easy way to do this. I know because I work for the company that builds it.

P.S. Butt-scans work great and can be done in a single pan in about 90 seconds.
