Volumental is a simple web app that aims to handle all of that previously manual stuff automatically. The process goes like this: you take a depth scanner, like a Microsoft Kinect, plugged into your laptop. Pointing the depth sensor at the object to be scanned, you walk all around it, shooting it from all angles. That data is turned into a .obj file. So far, Volumental has already created and released all of these tools; you can use them here, right now.
