Patterns are classified according to spatial forms.

2. Freehand brushwork-perceptual thinking

3. Realistic form-thinking in images

The organizational characteristics of patterns are organization and repetition. Coherence and repetition constitute the rhythm and rhythm of the pattern, thus obtaining the decorative beauty of the pattern. When we design a pattern, whether geometric, freehand or realistic, we should study it carefully and scrutinize its simplex repeatedly. Only with the perfect simplex can we lay the foundation for the next design. Therefore, simplex design is very important in the following three types of modeling.

Geometry: Geometric patterns have a long history and are widely used. In textile pattern design, machine printed cloth, brocade and embroidery are widely used. Many traditional brocade patterns in China are hexagonal, rhombic, zigzag, zigzag and other geometric patterns, and some have geometric patterns as the background. Modern plane structures are also geometric patterns.

Significance of geometric pattern: Geometric pattern is the simplest way to embody the law of formal beauty, which is of great significance to creative thinking.

Simplex design of geometric shape: The so-called simplex is the smallest unit shape in the fingerprint sample.
