By taking pictures of different angles a point cloud can be generated from the depth data which can be triangulated into a 3D model. I own a 3D printer and hope 3D scanning apps will soon be available. On the other hand, this demo is showing 3D generation by just filming the object: https://www.youtube.com/watch?v=vEOmzjImsVc https://www.youtube.com/watch?v=vEOmzjImsVc I wonder why this didn't take off.

> I wonder why this didn't take off. I think mainly because there isn't much of a usecase for most people. We use Structure from Motion techniques a lot here where I work (Research Institute) to construct 3D models of buildings and land from UAV imagery. The current methodologies are great for this use, but they lack the accuracy you'd want to model an object on your desk for 3D printing. That's not to say you can't do it - there's just often a lot of work to be done on the mesh afterwards to make it work. Autodesk make a pretty good app called 123D catch [0], which uploads your images to their servers for processing. Alternatively VisualSFM[1] is what I mostly use, I get great results but I don't know how good it is with small things.

I've been doing this stuff for a while. I can make 3d models from photos using VisualSFM and CMPMVS. It produces good results. I guess it hasn't taken off because for most people this is not cool. What does the average person do with this tech? Making mini statues of yourself is a nice application but most people find it a little creepy - not cool. I suppose it's like when photos started being a thing - it took a while for people to accept it. It took money and power to force it into peoples consciousness so that they could appreciate it.
