The people from Autodesk (AutoCAD) are about to launch an iPad-app that will make 3D modeling a bit more accessible for the mainstream.
123D Catch for iPad
With the 123D Catch for iPad app it is possible to create a 3D model from a few photo’s. What you basically do is first choose an object you would like to print. Then you take around 50 to 70 photo’s from different angles while circeling the object twice. Each time you take a photo you adjust your position just slightly. The 123D Catch app then converts the 2D photo’s into an 3D model ready to print. 123D Catch for iPad will launch in April.
