3D scanner: 3D scanning implies analyzing the real-world environment or objects for collecting data on their appearance, i.e. color and shape. Digital 3D models can be constructed from the data collected. Such devices are being used by the amusement industry extensively for producing video games and movies. This technology is more widely used in reverse engineering, industrial design, prototyping, keeping records of cultural artifacts, and computer vision. A number of technologies have been used for building the three-dimensional scanning devices. Every technology has limitations, costs, and advantages.
Functionality: The idea behind using a three-dimensional scanner is creating a Point Cloud of the Geometric Samples on the subject’s surface. The subject’s shape can then be extrapolated by using these points. If information regarding color is gathered at every juncture, the determination of colors on subject’s surface can be easily done. 3D scanners share analogy with cameras. If one tries to define a Spherical Coordinate System wherein the origin would be the scanner and vector would be drawn from front of it such that θ=0 and
