It is a three-dimensional plastic art to use certain material materials to produce works of art with solid image. Because the production methods are mainly sculpture and molding, it is called sculpture. According to the production process, sculpture can be divided into two categories: sculpture and sculpture. Subdivision is divided into carving, carving, molding, chiseling, carving, casting and other skills and techniques. According to genre, sculpture can be divided into memorial sculpture, urban garden sculpture, sculpture, tomb sculpture and exhibition sculpture. According to the style, sculptures can also be divided into head portrait, bust portrait, bust portrait, full body portrait, group portrait, etc. According to the technique and form of expression, sculpture can be divided into three categories: round sculpture, relief sculpture and openwork sculpture. Round sculpture, also known as "muddy sculpture", is a three-dimensional sculpture that is not attached to any background and can be viewed from all sides. The round sculpture is characterized by a solid image standing in space. When creating it, one must take into account its sense of volume and weight. When shaping the image, one must also take into account that people watch it from different angles. Relief, also known as "relief", is to carve a convex artistic image on the plane. According to the different degrees of surface relief, relief can be divided into high relief (high and low relief, deep relief) and low relief (low and low relief, shallow relief). The openwork is between the round sculpture and the relief sculpture. On the basis of the relief sculpture, it is made by hollowing out the background, but it does not leave the plane, just like a round sculpture attached to the plane background.

Exterior wall decorative panel is a new type of integrated material for building exterior wall decoration and insulation developed in recent years, which is composed of polyester baking paint or fluorocarbon paint, carved aluminum zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth; Danzhou EPS line It is mainly used for exterior wall decoration and energy-saving reconstruction of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; The main functions are building decoration, heat preservation, energy conservation, heat insulation, sound insulation, waterproof and mildew proof. The metal surface decorative insulation board is a large-area external hanging wall board produced industrially. It has good durability and low maintenance cost due to dry installation and construction. It integrates the functions of external wall insulation and decoration, and meets the requirements of high quality EPS line The development direction of building energy conservation "modularization" technology is an advanced technology vigorously promoted in the field of building wall external insulation technology in China.

Shallow relief has a low rise, a large compression of shape, a strong sense of plane, and is closer to the form of painting to a greater extent. It does not rely mainly on physical space to create space effects, but uses more painting techniques or perspective, illusion and other processing methods to create more abstract compression space, which is conducive to strengthening the dependency of relief suitable for the carrier. The ancient Assyrians of Mesopotamia were probably the artists who were best at performing art by this means. In a series of "Assyrian Hunting Pictures", they used the technique of bas relief very well to express the lively artistic image with a sense of rhythm and rhythm, and to show the inner feelings of the characters and animals with complex dynamics. The selection of the compression degree of relief space usually takes into account the function, theme, environmental location, light and other factors of the performance object, of which the environment and light factors play a decisive role. Excellent sculptors can always handle these relationships well, so that the works can achieve good visual effects.

The original main application scope of the flexible shaft machine is large-scale jade carving works that cannot be carried by the desktop computer. It is usually used with handheld devices such as the electric mill to complete the detailed work that cannot be carried out by the electric mill. Since the fixed grinding head of the desktop computer is not as flexible as the handle in handling some types of devices, many people will also choose to apply the flexible shaft machine to some smaller or more special types of devices. Due to the continuous improvement of fine requirements for jade articles, jade carvers in China are constantly looking for and trying more favorable equipment. The dental machine is the medical equipment borrowed from the dentist by the jade carver. Its flexibility is the best of all models at present, so it is mainly used for detail processing, but has little application value in heavy work.

In the history of human civilization, ancient artists have used many experienced forms, including architecture, gardens, sculpture, painting, literature, etc., to make these humanistic environment spaces convey more abundant ideological connotation and show more strong artistic charm. The overall layout of these works is rigorous and thorough, and the scenes are grand. Various artistic means, such as architecture, gardens, music, painting, cultural relics display, film slides, torch lights, waterscape lights, are mobilized. Focusing on the common theme, each of these works gives play to its unique image language, forms a sequence space that unfolds layer by layer, and enhances rendering from visual and auditory perspectives, It influences the various senses of the viewer in an all-round way. The multi-level whole process, from sensibility to rationality, has fully expanded its breadth and constantly excavated its depth, which has led people deeply into a specific mood and mood, and then promoted them to a comprehensive and profound understanding of the event. At the same time, people have experienced a complete aesthetic process. The functional nature of the large-scale art complex with sculpture as the main body is mainly the commemorative enlightenment effect.

Auxiliary tools for wood carving: mainly hammer, wood file, axe and saw. The purpose of the axe is to cut a large amount of wood with the help of paring. Pay attention not to use too much force when cutting. Do not cut straight up and down. The edge of the axe should be kept at about 45 degrees with the vertical wood grain, otherwise the wood will crack. Hainan GRC component wood file is mainly used in the fine blank stage of round carving, which can replace the flat knife to smooth the chisel marks for polishing; It can also take the place of round knife or oblique knife for hollowing. The function of the wood file is also that it can quickly adjust the modeling structure in a large area, and can be used in combination with the carving knife to make the turning and turning of the figure's clothing patterns vivid and smooth, with both virtual and real effects. The shape of hammers for wooden sculptures in Hainan is flat, flat, wide and square. The dimension of hammer face can be controlled at about 7 × 5.5 × 2.5 cm. Too narrow or too thick will affect the accuracy of the hammer's landing point and the uniformity of force. There are two kinds of hammers: wooden hammers and iron hammers. The wooden hammers generally use hardwoods with a large proportion of wood, such as mahogany, boxwood, sandalwood, beech and fruit trees. The specifications can be controlled at 27 cm in length, 55 cm in width and 45 cm in thickness; The grip is round and slightly flat, and the size is suitable for holding in the hand.
