Polycam is a 3D scanning application that utilizes Photogrammetry and LiDAR data from your iPhone (as of updating this there is an Android release too) to create a 3D model. This was my first introduction into scanning and Augmented Reality via model viewing.
These are some things I've scanned:
This is a dinosaur sculpture I found on the side of the road by the MOST in Syracuse.
This is a pendant light on the outside of the State Tower building entrance (Syracuse, NY).
