Modeling is a way of expression in the field of visual arts. Through artists' creation, concrete images and abstract concepts are expressed by lines, shapes, colors and textures, so as to achieve the purpose of expressing and conveying feelings, thoughts and aesthetic feelings. Modeling can be applied to painting, sculpture, architecture, clothing design, product design and other fields, and has a wide range of application values.

The realization method of modeling is mainly to express the external characteristics and internal spirit of an object or image through the combination of lines, shapes and colors. Lines can be used to express the outline, structure, posture and dynamics of objects. Shape can represent the size, proportion, spatial relationship and structure of an object. Color can express the texture, emotion and meaning of an object. Through the use and combination of these elements, we can create a variety of modeling forms, such as realism, semi-abstraction, abstraction and so on.

When creating shapes, artists need to consider the composition of images, the accuracy of shapes and proportions, the fluency of lines and the coordination of colors, so as to create works with appeal and beauty. Modeling is the foundation and core of visual art, which is of great significance for learning and mastering art forms such as painting, sculpture and design.
