What's the difference between three dimensions and four dimensions?

1, 3D: 3D consists of one dimension and two dimensions, that is, the two dimensions are only staggered in two directions, and the first dimension and the first dimension are superimposed together to get 3D.

4-D: 4-D is 4-D, consisting of countless 3-D, and 3-D consists of countless 2-D..

Second, the characteristics are different.

1，3D:？ The spatial target is defined by three coordinate axes: X, Y and Z, and the spatial relationship is divided on the basis of volume, which is obviously complicated. ? Can express the objective world more truly; Can carry out three-dimensional space analysis and operation.

4-D: Each axis of 4-D is perpendicular to each other.

Third, the use is different.

1, 3D: 3D animation, not limited by time, space, place, conditions and objects, uses various forms of expression to show complex and abstract program contents, scientific principles and abstract concepts in a centralized, simplified, vivid and vivid form.

Three-dimensional virtual, referred to as VR technology is called VR technology. Suitable for tourism, real estate, museums, subways, airports, stations, docks and other industries.

2. Four dimensions: describe the number of space-time coordinates.
