  1. FIRST!! 🙂

    To the person who did this last week. The answer is no… people don’t do this anymore but it just shows how old you and I are in the age of the internet.

  2. Regarding the structure sensor, it has not changed, it is literally the same device you used years before. Still does not have a laser 😉 Just infra red light.

    All the improvements are software based 🙂 Both geometry detail and texture detail have gone way up.

    The result from the software is not more detailed than a reduced mesh (unless you use crap software to reduce), it just has a whole bunch of unnecessary polygons, which is a result of the process, same goes for the Artec scanners and Photogrammetry setup’s, Scanning a perfectly flat and square surface would theoretically only need 4 vertices, 2 triangles/1 polygon, but the scanning process gives you hundreds, just because it probes all over the place. You can reduce those hundreds back to 10 or even 2. You reduce the amount of ploy’s but lose no detail whatsoever.

  3. good to know! in your experience, how many faces/polys do you reduce your scans to before exporting? i’m having good results in the 500k-1M range, down from ~5M in the original scans of human subjects.

  4. It depends on the scan. I export them as they are from scanect, then run them through zBrush which is a lot better at reducing and retopo than scanect is. You have some good control over where you want edges/poly’s to go, giving me more flexibility if I want to rig the scans for posing after he fact. I usually do some clean up to make sure I don’t run into issues with full color sandstone printing. For a full body scan I usually end up between 250k and 500k poly’s, depending on the size of the person and how intricate their clothing and hair is.

    A short haired 10 year old in jeans and a t shirt uses a lot fewer poly’s than George RR Martin wearing a frilly pirate blouse with a long sash and feathery hat 😛
