A 3D scanner is a device that analyses a real-world object or environment to collect data on its shape and possibly its appearance . The collected data can then be used to construct digital three-dimensional models.
Collected 3D data is useful for a wide variety of applications. These devicesare used extensively by the entertainment industry in the production o
f movies and video games. Other common applications of this technology include industrial design, orthotics and prosthetics, reverse engineering and prototyping, quality control/inspection and documentation of cultural artifacts.
