Research of computer-generated algorithms for traditional Chinese realistic paintings based on 3D model

Non-photorealistic rendering (NPR) is becoming a research hotspot in the field of computer graphics in recent years. There have been a lot of achievements about computer algorithm for western paintings. It is still at a preliminary stage for Chinese paintings. The only related work is about freehand brushwork in traditional Chinese paintings instead of traditional Chinese realistic paintings. A novel algorithm for computer-generated Chinese realistic paintings based on 3D models is proposed in this paper. Getting started with the imported STL file of flowers, topological relations among their geometric elements are constructed, and then a polygon mesh model of flowers is reconstructed. With the extraction of information including contours, projected outlines and feature curves of petals with the appropriate algorithms, a fine traditional Chinese realistic painting is obtained with projection and coloration algorithms. Furthermore, a simple mechanics model is used to simulate the flowers swaying in the wind, thus a computer animation for traditional Chinese realistic painting is produced.
