Noun explanation of three-dimensional graphics

Three-dimensional graphics have two meanings: one refers to physical pictures of nature, such as houses, tables and chairs, animals, plants and so on.

2. Geometry is different from plane graphics. Plane graphics only have two-dimensional graphics in the horizontal plane, and three-dimensional graphics add an axis perpendicular to the plane on the basis of plane graphics, which is also called three-dimensional space graphics. In the three-dimensional coordinate system thus established, any point (a) in space can be represented by the abscissa (x), the ordinate (y) and the ordinate (z):

A(x, y, z) is convenient for learning and discussing the correlation of points, lines and surfaces of various spatial graphics, which is of great help to spatial thinking.
