Among the projection theories that can be seen in ancient Chinese literature, there are similarities to what we now call central projection, parallel projection and oblique projection. Whether Zong Bing’s perspective on perspective in the 4th and 5th centuries AD, or From the 11th to the 12th centuries, the theoretical summary of Guo Xi and Shen Kuo not only laid the theoretical foundation of ancient Chinese engineering drawing, but also reflected the development course of Chinese engineering drawing theory from focus perspective to scattered perspective. Contribution to world map science.
