Three dimensions are three axes of coordinate axes, namely x axis, y axis and z axis, wherein x represents left and right space, y represents upper and lower space, and z represents front and rear space. However, in practical application, the X-axis is generally used for left-right movement, the Z-axis is used for up-down movement, and the Y-axis is used for front-back movement, so that the visual stereoscopic impression of people is formed.
