I’ve just found some software by Autodesk that can create 3D models from photographs… maybe suitable for 3D printing!!!
It’s called 123D Catch… it will export 3D models in .obj format so they will need to be converted to .stl in a program such as meshlab and I suspect that some mesh editing will be needed to make them into manifold objects etc.
I haven’t had time to experiment yet .. you need at least 3 different photos of an object to make the model, it’s getting late in the evening and my camera batteries are dead … grrrr.
If you fancy a go yourself the software can be found here http://www.123dapp.com/catch … just wondering how I can use this in school with my students 🙂
