How to explain the continuous pattern of two sides?

Bidirectional continuous pattern is a pattern formed by repeating a single pattern left and right or up and down.

A quadrilateral continuous pattern is a pattern consisting of a single pattern repeated in the left, right, up and down directions. Quadrilateral continuous pattern refers to the unit patterns that are repeatedly and continuously arranged in the up and down direction or the left and right direction, resulting in beautiful, rhythmic and vertical horizontal or vertical strip patterns. Also called lace pattern. When designing, we should carefully scrutinize the image insertion, scattered size, contrast between simplicity and complexity, color echo and reprocessing of connection points in the unit pattern. Double-sided continuous patterns are widely used in architecture, book binding, packaging tape, clothing edging, decorative spacing and so on. The bidirectional continuous pattern is divided into the following tissue forms according to the changes of basic bone types: 1. Decentralized bidirectional continuous mode is generally a complete and independent individual mode. They are distributed in the form of scattered points, and there is no obvious connector or connecting line between them, which is simple and lively, but easy to be stiff. The unit pattern T can be composed of two or three single patterns with different sizes and complexity, which will produce a certain sense of rhythm and rhythm, and the decorative effect will be more vivid. 2. The unit patterns of wavy bidirectional continuous patterns are connected smoothly with wavy curves. 3. The two-way continuous pattern with broken lines has obvious moving effect, and the continuous and flexible unit patterns are connected by turning with broken lines. The corners of various broken lines formed by straight lines are obvious and strong. Jumping lively 4. Geometrically connected two-sided continuous patterns are connected in the form of circles, diamonds, polygons and other geometric shapes, and strong surface effects are produced after segmentation. Pay attention to the size and color matching of the positive and negative shapes when designing. 5. The combination of the above two-way continuous patterns on the comprehensive platform can produce two-way continuous patterns with diverse styles and rich changes.
