3D scanning
There are many types of 3D scanning:
Touch-probe scanning
Structured-light scanning
This is making a 3D file of an object just using a camera, or a camcorder with a projected grid from a video projector or a projected line from low paper laser light source (a laser-pointer).
Closed source, the kit requires €400 and a Windows computer
Photogrammetry scanning
This is making a 3D file of an object just using a camera, or a camcorder, even without a laser-pointer-like light source.
Technically this is called 'photogrammetry' or 'object reconstruction':

Possibly unrelated from my original source text: (Maybe 10 years from now all the art schools that want will have as many casts as they can 3D print. I think I know what I'm doing on my next trips to art museums.) See also David_Project.
