Abstract: In this paper we present a programmable graphics hardware supported system to render 3D mountain models with the effect of Chinese painting.During the off-line preprocessing,we construct a set of texture images corresponding to different layers of mountains,strokes in the textures are distributed un-uniformly with different tones.At run time,the system first detects positions of mountain models to determine which layer they belong to,and blends the corresponding textures according to the luminance derived from the artistic light model.The bottom part of the mountain is blended with the fog picture to generate the final image with the effect of Chinese painting.
