Almost all computer systems shipped today have some form of 3D graphics. But most of the marketing and advertisements never really describe what 3D graphics are or why 3D graphics are useful.3D graphics in general are used to create realistic looking environments that are visible through the 2D screen of a computer monitor. These environments are designed to be fully immersive – meaning the user can "see" or "move" in any direction, at will. The most sophisticated of these environments are highly interactive, allowing users to move or change the appearance of objects.
