What is a 3D game?

3D game is a game that uses spatial stereo computing technology to realize operation. From the programming point of view, the basic model of the game (characters, scenes and basic terrain) is realized by three-dimensional model, and the character control of the game is realized by spatial three-dimensional programming algorithm, so this game is called 3D game.

D in 3D is the abbreviation of Dimension. The position of a point in a three-dimensional game is determined by three coordinates (x, y, z). The real space of objective existence is a three-dimensional space with three dimensions: length, width and height. Three-dimensional games (3D games are also called stereoscopic games) are relative to two-dimensional games (2D games are also called plane games). Because they adopt the concept of three-dimensional space coordinates, they are more realistic and casual in space operation. And more attractive.

Extended data:

3D stereoscopic games are different from 3D games, and the main difference lies in the display system and viewing mode. The reason why human vision can distinguish distance is because of the difference between two eyes. People's eyes are about 5 cm apart, and nothing will have the same angle except aiming straight ahead.

Although the gap is very small, it is transmitted to the brain through the retina, and the brain uses this tiny gap to generate the depth of distance, thus creating a three-dimensional sense. Although one eye can see objects, it is not easy to tell the distance between them. According to this principle, if the same scene is made into two images by using the difference between the two eyes, and then each eye sees its own image on one side, the depth of field can be stereoscopic through the retina.
