What is the difference between three dimensions and four dimensions?

1. Different compositions

1. Three-dimensional: Three-dimensional is composed of one-dimensional and two-dimensional. Two-dimensional means that there are only two directions of interlacing. One two-dimensional and one one-dimensional The three dimensions are obtained by superimposing the dimensions together.

2. Four dimensions: Four dimensions are four dimensions, which are composed of countless three dimensions, and three dimensions are composed of countless two dimensions.

2. Different characteristics

1. Three-dimensional: The spatial target is defined by the three coordinate axes of X, Y, and Z. The spatial relationship is divided based on the volume, and the complexity is obvious; Express the objective world more truly; enable three-dimensional space analysis and operation.

2. Four dimensions: Each axis of the four dimensions is perpendicular to each other.

3. Different purposes

1. Three-dimensional: Three-dimensional animation is not limited by time, space, location, conditions, or objects. It uses various forms of expression to transform complex and abstract programs into Content, scientific principles, abstract concepts, etc. are expressed in a concentrated, simplified, vivid and vivid form.

Three-dimensional virtuality, referred to as VR technology. It can be used for project display and promotion in tourism, real estate, museums, subways, airports, stations, docks and other industries.

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