What is the primary difference between a 2D and a 3D scanner?
2D scanners only scan text, while 3D scanners scan images.
2D scanners capture two-dimensional images, while 3D scanners capture three-dimensional data of an object.
2D scanners use lasers; 3D scanners do not.
2D scanners scan documents, while 3D scanners scan people.
Обяснение
The fundamental difference is that a 2D scanner generates a 2D image while the 3D scanner generates a 3D representation of the object.
