What is a 3d scanner?
3D technology is utterly fascinating, as it produces and displays moving pictures in all three dimensions and enhances the illusion of depth perception. In the same field of technology, 3D scanner represents an impressive device which makes to the real world, object or environment a computerized axial tomography in order to obtain information about its shape and appearance. After the scanner has collected the needed data, it is ready to construct innovative, three dimensional models. For more information on the way 3D scanning works, please check out 3D film or 3D technology on Wikipedia.
The aim of a 3D scanner is to produce a point cloud on the external part of the object, in order to use them for the object’s profile reconstruction. If information about the color of the target can be accumulated at each point, then the color range of the object can also be defined. Moreover, 3D scanning machines are highly similar to cameras, like cameras, they can only record data about areas that have enough lightning, so 3D scanning must be done in proper conditions, otherwise the machine may fail. For most situations, 3D scanning may need multiple scans, even hundreds, from many different angles in order to gather enough information about all parts of the object as it may not provide a complete model from just one scan.
Collected 3D data are particularly useful for a wide range of applications, especially in the entertainment area, in the making of movies and video games, but the 3D software also includes industrial design, prototyping, quality control of cultural artifacts or reverse engineering. For instance, 3D films and games became more and more successful because of this technology, as people are more and more enthusiastic about it because of its spectacular way of giving life and motion to the most fascinating characters.
