What is the concept of three dimensions?

The concept of three dimensions is as follows:

Three dimensions refer to a space system formed by adding a direction vector to the plane two-dimensional system. Three dimensions are the three axes of the coordinate axis, namely the x-axis, y-axis, and z-axis, where x represents the left and right space, y represents the front and rear space, and z represents the upper and lower space (the plane rectangular coordinate system cannot be used to understand the spatial direction).

In terms of practical applications, the X-axis is generally used to describe left and right movement, the Z-axis is used to describe up-and-down movement, and the Y-axis is used to describe forward and backward movement, thus forming a human visual three-dimensional sense.

Three dimensions are composed of one dimension and two dimensions. Two dimensions only exist in two directions. Three dimensions are obtained by superimposing one two dimension and one one dimension. Three dimensions are three-dimensional, and front and back, left and right, up and down are only relative to the viewing point of view. There is no absolute front and back, left and right, up and down.

Application:

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

The way 3D animation technology simulates real objects makes it a useful tool. Due to its accuracy, authenticity and unlimited operability, it is widely used in many fields such as medicine, education, military, entertainment and so on.

In terms of film and television advertising production, this new technology can give people a refreshing feeling, so it has been welcomed by many customers. Three-dimensional animation can be used for special effects production (such as explosions, smoke, rain, light effects, etc.), stunts (car crashes, deformations, unreal scenes or characters, etc.), advertising product displays, opening credits, etc. in advertisements and movies and TV series.

Three-dimensional:

Three-dimensional paintings are paintings made using the phenomenon of stereoscopic vision of the human eye. Ordinary paintings and photography, including computer-generated three-dimensional animations, only use the human eye's perception of light and shadow, light and shade, virtuality and reality to achieve a three-dimensional feeling.

Without the use of binocular stereo vision, one eye and two eyes see the same thing. Stereoscopic paintings that make full use of the stereoscopic vision of both eyes will allow you to see a wonderful world.
