I'm Bart Veldhuizen, I'm the Head of Community for Sketchfab and I work from the Netherlands. We consider ourselves the 'youtube of 3D', allowing artists to embed interactive 3D models on their websites.
I often use a Structure scanner at events to scan people and it always draws a crowd! I mainly use ItSeez3D because of the ease of use and quality of the results, but I'm diving into Skanect Pro now as well.
We see a lot of 3D scanning activity in our community, and also have a weekly '3D Scanning Thursday' challenge. This week's topic is 'Travel'. Scroll down to see the first entries, and feel free to join in!
I'll lurk around here to pick up tips and tricks, especially any that would make scanning at events easier/more efficient
