实时绘制3D中国画效果

介绍了一个利用可编程图形硬件对3D山峦模型进行实时水墨效果绘制的系统．首先建立对应于不同层次的一组纹理图像，图像中的笔刷纹理按照手工绘画那样非均匀分布并构成明暗变化的纹理序列．系统在运行，首先检测山峦模型的位置来确定它所在的层，然后根据山峦模型的光照值对相应的纹理进行混合，山峦底部则与背景的云雾图进行混合，以得到最终的具有国画风格的画面．

Real-time Rendering of 3D Chinese Painting Effects

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
