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