Research on Real-Time ink Rendering

"Wu Daozi painted mountains and rivers, with a pen without ink; items with ink without ink; I am the director of the second son, into a house ."
Chinese painting has a long history and has a rich and colorful heritage, unique and distinctive artistic characteristics. It has its own system and uniqueness in the East and the world. In the unique Chinese painting, the literati ink painting can best reflect the characteristics of Chinese painting.
An important feature of literati ink painting is to change the green color and depict it as ink rendering. Ink and ink are the core of Chinese painting. Today we talk about pen and ink. They are mostly used together to refer to the basic techniques of Chinese painting. In fact, there is a large area between pen and ink. In terms of skill, pen refer to tick, le, Yi, Dot and other pen methods, there are light, heavy, Xu, disease and other changes; ink refers to drying, dyeing, broken, stains and other ink, there are thick, light, dry, wet and other differences. Traditional Chinese Painting before the Tang Dynasty, first with a pen sketch, and then fill in the color, a bit similar to the western painting first sketch, then on the color Program. This painting method emphasizes graphics rather than pen and ink. Chinese painting has changed from focusing on graphics to focusing on pen and ink. It occurred in the Tang Dynasty. Wang Wei and Zhang Yu, painters of the Tang Dynasty, have reformed the traditional painting methods and directly painted with ink, which emphasizes the importance of ink. Jing Hao, a famous painter from the Tang Dynasty and the Five Dynasties, once said: "Fu with class Fu CAI has been available since ancient times. Such as water dizzy mozhang, and my Tang Dynasty "(" Writing Method ")
Currently, the commonly used methods for Computer Simulation of ink rendering are fluid simulation and Cellular Automation machine (CA). These two methods are often used in combination to achieve satisfactory results. With the rapid development of GPU, computer simulation has achieved real-time results.
GPU real-time ink rendering is as follows:
