Please talk about how to understand the research on the physical space and visual differences of sculpture.

A plastic arts. Sculpture, also known as sculpture, is the general name of three creative methods: carving, carving and plastic. Refers to the use of various plastic materials (such as gypsum, resin, clay, etc.). ) or hard materials (such as wood, stone, metal, jade, agate, etc.). ) Create a visual and tangible artistic image with a certain space, so as to reflect social life and express the artist's aesthetic feelings, feelings and ideals. Engraving and carving achieve the purpose of artistic creation by reducing the materials that can be carved, while plastic achieves the purpose of artistic creation by piling up plastic materials. Round carving, relief carving and through carving are its basic forms. In the same environment, a group of round sculptures or reliefs are used to express the same theme, which is called group sculpture. The emergence and development of sculpture is closely related to human production activities, and it is also directly influenced by social ideologies such as religion and philosophy in various times. When humans were still in the Paleolithic Age, primitive stone carvings and bone carvings appeared. Sculpture is a relatively permanent art, many ancient things have disappeared after being washed away by the long river of history, and the sculpture heritage of past dynasties has become the history of human image in a certain sense. Traditionally, sculpture is a static, visible and touchable three-dimensional object, which reflects reality with the help of visual space images, so it is considered as the most typical plastic arts, static arts and space arts. With the development of science and technology and the change of people's ideas, anti-traditional four-dimensional sculpture, five-dimensional sculpture, acousto-optic sculpture, dynamic sculpture and soft sculpture have appeared in modern art. This is because Einstein's theory of relativity has broken through the world outlook established by Newton's theory, changed people's view of time and space, made sculpture art understand and express the world from a higher level, broke through the three-dimensional, visual and static forms, and explored the multi-dimensional time and space mentality.

In short, it is to make all kinds of artistic images with real volume by means of carving, cutting, carving, grinding and plastic, which is always called sculpture. It is called plastic arts together with architecture, painting and arts and crafts. Sculptures are generally divided into circular sculptures and relief sculptures. According to its size and shape, it can be divided into two categories: large sculpture and small sculpture. According to their different functions, it can be divided into religious sculpture, mausoleum sculpture, monument sculpture, decorative sculpture, garden sculpture, fountain sculpture, folk sculpture, easel sculpture and so on. According to their materials, there are sculptures made of clay, wood, stone, brick, copper, pottery, tooth, porcelain, jade, bone, lacquer, bamboo and other metal and chemical materials. No matter what kind of material is used in sculpture, it has its modeling rules and limitations. Sculpture is a tangible space plastic art, and the image of sculpture itself has no perspective relationship, and circular sculptures can be appreciated from all directions. Sculpture can make people feel different because of different viewpoints, different places, different light and different materials.
