What are the visual manifestations of the case?

Patterns can be divided into concrete patterns and abstract patterns according to their forms of expression. Figurative patterns can be divided into flower patterns, landscape patterns, figure patterns and animal patterns according to their contents. Figurative pattern occupies a prominent position in pattern design, which is created by people from the natural form of figurative beautification. The design of concrete patterns should get rid of the bondage of pure nature, and obtain natural forms by inductive methods to make them have the beauty of patterns. The design pattern must have a thorough understanding of the media objects, and at the same time, it should also choose the expression mode suitable for the content. Abstract patterns are suitable for music, art, philosophy, religion, information and other content that has no specific shape to visualize. Abstract patterns are not suitable for tourist posters in specific areas or promotional posters of specific commodities.

Abstract patterns have amazing expressive power in computer design, and now they have gone further from the previous composition of points, lines, surfaces, colors and textures, trying to express the illusion effect or light art with colors or lines. The composition of the pattern is to recombine the changed images according to different use requirements, technological conditions, different materials and the laws of formal beauty, so that the pattern organization becomes an orderly and regular whole. As far as the organizational form of plane pattern is concerned, it can be summarized as single pattern and continuous pattern. Compared with continuous patterns, single patterns can be used for decoration alone, and can also be used as basic patterns and suitable patterns to serve bidirectional and four-way continuous patterns. It needs a complete pattern and relatively independent features. Continuous composition is a kind of organizational form in decorative patterns, which is a continuous pattern formed by arranging a basic unit pattern up and down, left and right, or repeatedly in four directions. Patterns are regularly arranged and orderly overlapped, giving people a simple feeling.
