Wrinkle Rendering of Terrain Models in Chinese Landscape Painting

Abstract

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 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.

DEM based Terrain Sketch Mapping in a Loess Landform by considering visual hierarchy and feature generalization

“…With the rapid development of computer visualization and digital terrain analysis methods, computer-assisted terrain sketches based on DEM may be automatically generated, depending on geographic cognition theory and the sketch description method.Previous research has generated terrain scene maps based on DEM data and has produced various styles of terrain maps, i.e. oil painting, ink painting, pen and pencil sketch maps (Visvalingam et al 1998, Whelan et al 2003, Way et al 2006, Bhattacharjee et al 2008). However, those computer-drawn sketch maps have focused on the artistic effect rather than depicting terrain features and landform structures.…”
