Most of the jades mentioned in daily life refer to nephrite, and there are many kinds of nephrite products. Generally, they refer to white sheepskin jade, white jade, topaz, purple jade, black jade, jasper, sapphire, ruby and northeast Xiuyu produced in Xinjiang. In the jade carving, the white jade with sheepskin is fine in texture and strong in luster, as white as sheepskin, which can be called "the king of nephrite" and "the crown of white jade". In addition, Nanyang jade, Lantian jade, Hotan jade, agate, crystal, coral, turquoise, lapis lazuli, etc., all belong to the category of nephrite. Later, due to the opening of the Silk Road, the jade produced in Hotan, Xinjiang, was unanimously recognized and began to play a leading role in the processing of royal, official and folk jade. Nephrite gradually evolved into a synonym for hotan jade.
Stone carvings pay attention to lifelike shapes, round and delicate techniques, and smooth and free patterns. Its traditional skills began in the Han Dynasty, matured in the Wei and Jin Dynasties, and became popular in the Tang Dynasty. There are mainly garden sculptures, architectural sculptures, sculptures, stone carving handicrafts, and hundreds of products: marble mantelpiece, figure sculptures, reliefs, abstract sculptures, fountains, flower pots, Roman columns, railings, pavilions, busts, door covers, stone benches, bathtubs, animal carvings, tombstones, antique sculptures, etc. Stone carvings have a long history. They pay attention to lifelike shapes, round and delicate techniques, and smooth and free patterns. Carving products mainly include figures, animals, fireplaces, flower pots, balustrades, fountains, reliefs, dragon pavilions, dragon pillars, jade pavilions, birds and animals, and various high-quality sculptures. It not only has the charm of ancient art, but also has the elegant and fast modern art style. It enjoys the reputation of "excellent workmanship" and "groundbreaking" at home and abroad. It is a collection of creative, design, production of various works of art. In short, it is a work of art carved from stone.
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.
Components are reusable software modules oriented to software architecture. Gansu Stone sculpture It is a reusable software component that can be used to construct other software. It can be encapsulated object classes, class trees, some functional modules, software frameworks, software architecture (or architecture), documents, analysis pieces, design patterns, etc. In 1995, Ian Graham defined components as follows: Stone sculpture manufactor Component refers to an object (interface specification, or binary code), which is used for reuse, and the interface is clearly defined. Hainan sculpture component appears as a logic tight program code package with a good interface. For example, Ada's Package, Smalltalk-80 and C++'s class and data type can all belong to the component category. However, the operation set, procedure and function can not become a component even if they can be reused. Developers can develop new application systems by assembling existing components, so as to achieve the purpose of software reuse. Software component technology is the key factor of software reuse, and also the focus of software reuse technology research.
Circular sculpture, also known as three-dimensional sculpture, refers to non compressed three-dimensional sculpture that can be viewed from multiple directions and angles. Sculpture is the overall expression of art on the sculpture. The viewer can see all sides of the object from different angles. It requires the sculptor to carve from the front, back, left, right, top, middle and bottom. The techniques and forms of round sculpture are also varied, including realistic and decorative, concrete and abstract, indoor and outdoor, shelf and large city sculpture, colored and non colored, etc; The contents and themes of the sculptures are also rich and colorful, which can be characters, animals or even still life; The materials are more colorful, including stone, wood, metal, clay, gypsum, textiles, paper, plants, rubber, etc. It is mostly used in fountains, gardens and indoors. Because the round sculpture works are very three-dimensional, vivid, lifelike and vivid, the selection of stone materials is strict. First of all, we should design the shape of the sculpture, and pay special attention to the fact that the sculpture must have a proper proportion with the real object from length to width to thickness.
