What three dimensions does three-dimensional space refer to?

Three-dimensional space is a space in which the position of a point is determined by three coordinates, with length, width and height.

"Dimension" here means direction. The straight line pattern established by one direction is a one-dimensional space. The one-dimensional space is one-dimensional and established by the infinite extension of Х to both ends. The plane pattern established by two directions is a two-dimensional space. The two-dimensional space is bidirectional. The X and Y directions intersect to form a plane, which is established by the infinite extension of the two directions. In the same way, the three-dimensional space is three-dimensional and has three directions. The three directions X, Y, and Z respectively constitute a three-dimensional space, which is established by the infinite extension of the three directions.

Application of three-dimensional animation

1. Three-dimensional animation

Three-dimensional animation is also called 3D animation. It is not limited by time, space, location, conditions and objects. Use various forms of expression to express complex and abstract program content, scientific principles, abstract concepts, etc. in a concentrated, simplified, vivid, and vivid form.

2. Three-dimensional virtualization

VR technology is called VR technology for short. Used in tourism, real estate, buildings, villas and apartments, office buildings, scenic spot displays, sightseeing tours, hotels, restaurants, garden landscapes, park exhibitions, museums, subways, airports, stations, docks and other industry project display and promotion.

3. Three-dimensional murals

According to the British "Daily Mail" and "Daily Express" reports on the 26th, the 61-year-old American three-dimensional art painter John Pugh is the most famous in the world. Amazingly lifelike three-dimensional paintings are painted on the walls of many buildings across the country. Passers-by who don't know the truth often try to "walk into the paintings."
