At first, perspective was studied by looking at the landscape through a transparent plane. Draw the scene accurately on this plane, that is, into a perspective view of the scene. Later, according to certain principles, the science of expressing the spatial position, outline and projection of objects on a plane with lines is called perspective.
Imagine that there is a glass between the painter and the object to be painted, fix the position of the eyes (see with one eye), connect the key points of the object with the eyes to form a line of sight, and then intersect with the imaginary glass. The position of the point presented on the glass is the position of the point of the three-dimensional object to be drawn on the two-dimensional plane. This is the application method of perspective in western classical painting.

Origin:
Narrow perspective (that is, linear perspective) method is the product of Renaissance, that is, it reproduces the actual spatial position of objects in line with scientific laws. This method of systematically summarizing and studying the shape changes and laws of objects is the basis of linear perspective.
/kloc-The painting theory of Italian painter L.B. alberti in the 5th century describes the mathematical basis of painting and discusses the importance of perspective. Piero Della Piero Della Francesca, an Italian painter of the same period, made the greatest contribution to perspective. German painter A. Diu Lei applied geometry to art, which developed the science in theory.
At the end of 18, the right-angle projection method founded by French engineer Meng Qi completed the drawing method of correctly depicting any object and its spatial position, that is, the straight-line perspective method. L Leonardo da Vinci also created scientific air perspective and invisible perspective through case studies, which are collectively called perspective.
