Practiced for more than three thousand years, Chinese painting stresses the notion of "implicit meaning" in which painters use a minimum amount of strokes to express their deepest feelings. Chinese landscape and figure paintings are the two major themes of Chinese painting. Of relevant interest is more thoroughly understand Chinese art by analyzing basic rules of Chinese painting. This paper proposes two novel methods capable of synthesizing rock textures in Chinese landscape painting and synthesizing portraits in Chinese figure painting, respectively In addition to saving time during trial and error, these two methods attempt to synthesize painting styles. After users only specify the contour and parameters, our methods underwrite the complete painting process. With the requirement of familiarity with painting skills, individuals can paint various styles of Chinese painting.

Chinese ink painting is a traditional art that is over three thousand years old. It is a type of non-photorcalistic rendering. However, research on Chinese ink painting is scarce. Simulating the behavior of Chinese ink is challenging work because ink moves in a complex manner. This paper presents a new method for simulating ink diffusion based on observation and analysis. The proposed method can simulate various expressions of tones on different types of paper. The elucidation of the effect of mixing simulated strokes made by different kinds of brushes is an important contribution of the method. Finally, the simulated results are compared with real ink painting.

In Chinese landscape painting, rock textures portray the orientation of mountains and contribute to the atmosphere. Many landscape-painting skills are required according to the type of rock. Landscape painting is the major theme of Chinese painting. Over the centuries, masters of Chinese landscape painting developed various texture strokes. Hemp-fiber and axe-cut are two major types of texture strokes. A slightly sinuous and fiber stroke is used for describing the gentle sloped of rock formations whereas seemingly broken line, the hemp the axe-cut stroke best depicts hard, rocky surfaces. This paper presents a novel method of synthesizing rock textures in Chinese landscape painting, useful not only to artists who want to paint interactively, but also in automated rendering of natural scenes, The method proposed underwrites the complete painting process after users have specified only the contour and parameters.

Practiced for more than three thousand years, Chinese painting emphasizes "implicit meaning", and involves painters' using a minimal number of brush strokes to express their deepest feelings. Landscapes are one of the most important themes in Chinese painting, Trees are the essential painting objects. This paper presents a set of novel methods to automatically draw trees in Chinese ink painting from 3D polygonal models. Outline rendering and texture generation uses the information of the silhouette, shade and orientation of three-dimensional model's surface to draw a particular tree. Four reference maps are established to analyze the information for the bark texture. These methods can draw various styles of bark texture by defining the texture patterns. Finally, this paper demonstrates some results obtained with our method.

Landscapes have been the main theme in Chinese painting for over one thousand years. Chinese ink painting is a form of nonphotorealistic rendering. Terrain is the major subject in Chinese landscape painting, and surface wrinkles are important in conveying the orientation of Mountains and contributing to the atmosphere. Over the centuries, masters of Chinese landscape painting have developed various kinds of wrinkles. This work develops a set of novel methods for rendering wrinkles in Chinese landscape painting. A three-dimensional terrain is drawn as an outline and wrinkles, using information oil the shape, shade and orientation of the terrain's polygonal surface. The major contribution of this work lies ill the modeling and implementation of six major types of wrinkles on the surface of terrain. using traditional Chinese brush techniques. Users can select a style of wrinkle and input parameters to control the desired effect. The proposed method then completes the painting process automatically.
