I. Introduction
Ink painting is one of the traditional painting forms of the Chinese nation. It is a painting drawn by the concentration of water and ink. It is said that it began in the Tang Dynasty, became in the Five Dynasties, flourished in the song and Yuan Dynasties, and has continued to develop since the Ming Dynasty and modern times. Its unique visual effect and Oriental unique aesthetic characteristics make it of inestimable value and irreplaceable position in the history of Chinese art. With the rapid development of computer graphics technology, traditional photorealistic rendering technology is becoming increasingly mature and standardized. Therefore, nonphotorealistic rendering research has gradually become the focus of graphics research at home and abroad [1]–[2]. In the research of nonphotorealistic rendering, the simulation of traditional painting art is undoubtedly one of the most attractive and challenging topics. While absorbing the nutrition of traditional painting art and carrying forward the achievements of traditional painting art, it puts forward new requirements for computer graphics and computer simulation technology.
