In this tutorial, industrial designer Eric Strebel shows you how to 3D scan an object, when you haven’t got a 3D scanner. Using a camera and photogrammetry–in Strebel’s case, Agisoft Metashape, as it runs on a Mac–you can get good results, provided you follow the preparation and photography tips shown here. From quickly salt-and-peppering the surface of the object to ensuring you’re taking the right kinds of photographs, Strebel’s tips should save you a load of time down the line.
