What is the golden ratio structure?

The golden ratio, also known as the golden section. Ancient Greek mathematicians discovered a law with beautiful value when dividing line segments. Widely used in art, photography and other fields. It divides a straight line into long segments and short segments, so that the ratio of small segment to large segment is equal to the ratio of large segment to whole segment, and the ratio is 1: 1. 18. This ratio has been considered as the best from ancient Greece to19th century. It is widely used by European architects, painters and classical sculptors in the Middle Ages. It is considered to be the most appropriate proportion division and has aesthetic value in modeling. In composition, the golden section rule is used, mainly in the use of golden section points, lines and surfaces. The golden section, in panoramic composition, is mostly the position of the main performance object or visual center, while in mid-shot and close-shot composition, it is mostly the position of the main part of the scene. In portrait composition, people's eyes are often treated near the golden section. Gold thread is often used as the location of horizon, horizontal line and skyline. We usually say the golden ratio, which is 0. The ratio of 6 18 is about 1/3. It is said that there is such a law of beauty in Venus sculpture, not that things are beautiful at this point, but that the whole is harmonious and comfortable at this point. When we draw still life, we usually start with a wine bottle, a plate and an apple. The golden triangle is formed because when the level is not very high, this composition is the most stable and won't make mistakes.
