Wrinkle Rendering of Terrain Models in Chinese Landscape Painting

摘要

Landscapes have been the main theme in Chinese painting for over one thousand years. Chinese ink painting is a form of non-photorealistic 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 on the shape, shade and orientation of the terrain's polygonal surface. The major contribution of this work lies in 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.
