Is it possible to use the ordinary camera of my smartphone to create a 3D model of some object? How can I do this?
There is special software to perform 3D imaging directly using a smartphone. The basic idea is the following - you take the photos of a given object from different angles, then feed these photos to the app, and then the app merges them together to build a 3D model of the object. There are many other requirements, options, and features for different applications. They will provide you with tips if necessary. There are such apps as Scann3D, ScandyPro, Sony 3D Creator, Qlone and some others. Try to search for them and pick the one which is the best fit for your needs.
