摘要
在数字流域三维虚拟仿真模拟和水利工程科学计算可视化研究中,水体的真实感模拟是一个重要的研究内容。主要针对海浪、河流、喷泉、瀑布、洪水等在虚拟现实、数字流域、港口海岸工程建设、水自然现象与水景观模拟等领域应用广泛的水体的构建方法进行了总结概括,分析比较了每种水体仿真建模方法的工作原理、优缺点及其适用范围,并给出了其典型应用案例。重点阐述了现阶段广为流行的,能够逼真模拟水体形态的流体动力学方法。最后从实时性、真实感、交互性三个角度对未来一段时期内水体仿真建模技术的研究动向进行了预测与分析,目的在于为有志于从事水体虚拟仿真建模的研究人员提供一定的借鉴和参考作用。
Abstract： Realistic modeling and simulation of water is one of most popular research topics in development of digital valley and scientific visualization of hydraulic engineering. The modeling technologies of some water bodies were surveyed, such as ocean waves, rivers, flood, fountains, waterfalls, and water waves, etc., which are widely used in virtual simulation of digital valley and development of waterscape domains. For every Mnd of modeling method, its principle, advantages and disadvantages and application scopes were analyzed ad compared. Some typical application examples were also presented. The hydrodynamics-based modeling method was introduced importantly. Finally future research issues on modeling technologies of water body were introduced, including real-time simulation technologies, photorealistic rendering technologies, and interaction technologies between water and solid.
