摘要
系统可实时绘制中国山水画中常见的物体并生成视频输出,它包括5个模块:多通道技术和新型国画山光照模型的山峦绘制模块、基于位移映射的云层模拟、基于纹理运动的瀑布绘制模块、基于广告牌技术的树木绘制模块和实时视频输出模块.前面4个模块利用GPU可编程特性控制其流水线,对任意三维场景,可实时绘制水墨画效果;用户可根据需要对系统中的各个绘制模块进行配置并实时漫游.
In this paper we present a hardware accelerated Chinese landscape painting rendering system, which accomplishes real-time rendering of hill, cloud, waterfall and trees commonly used in Chinese Painting. The system contains five modules: The multi-pass rendering of hill based on a novel Chinese painting illumination model, displacement mapping based cloud animation, texture mapping based waterfall simulation, billboard based tree shading and on-line video capture. By exploiting the flexibility and streaming mode of programmable graphics hardware, our system can be configured to simulate the effect of Chinese landscape painting for arbitrary three-dimensional scene and provide on-the-fly walkthrough as well as off-line editing. The proposed system can be easily extended to diverse applications ranging from computer animation, computer game and multimedia entertainment industries.
