The graphic coding of DNA sequence is the geometricrepresentation of DNA sequences by means of different notes and line segments in different positions.
The traditional modeling techniques are mainly focused on physical modeling and geometricrepresentation, so it makes the conceptual design of products not obtain effective technique support.
由于传统建模技术主要集中于物理建模和几何表示方面，致使产品概念设计阶段缺乏有力的技术支持。

The representation has no weight factors or control parameters, and it is geometric and affine invariant.
