This is an instructable on how to use a portable 3D scanning rig for capturing volumetric scenes, in a bit of a blend between photography and video. For 3D scanning of someone's head, check out this instructable. And for 3D scanning small objects, check out this one. Oh, and for what to do with your 3D scene scans, check out my lab's main work, volumetric printing.
And, if you happen to be in Hong Kong or Brooklyn let me know - sometimes a group of us volumetric digitizers go out and capture the souls of the locals.

The settings I used for these scans are shown as screenshots here.
Live scanning out and about on the mean streets is brutal on battery life and the CPU of these light Macbook Airs. If you add some power management apps to run in the background, you'll likely get about 2 hours of scan time with this setup.
I like to scan at Low resolution and then do a Medium or High resolution reconstruction after the scan is complete.
