| 摘 要： | 在虚拟现实系统设计中,真实自然的动态水面效果可增强场景的逼真感,使虚拟环境更加绚丽.而水面动态模拟的关键技术是在水面的真实感、实时渲染速度、计算机软硬件资源需求及实现虚拟现实系统难易度等几个方面寻求平衡.提出利用层次细节技术,采用动态纹理映射、波动水面的物理模型并结合材质贴图方法,实现具有反射、折射等效果的流动水面.该方法应用于室外景观等环境表现中,使水面效果更逼真、计算复杂度减小、设计和实现更简洁方便.

| Abstract: | In virtual reality(VR) system design,the natural surface effect can make the scene more real.The key technology of water surface dynamic simulation is keeping the balance among the sense of reality of the water surface,real-time rendering speed,the resources requirements of computer software and hardware and difficulty of realizing the virtual reality system.In the paper the writer propose using level of detail technology,using dynamic texture reflection and the way of model of fluctuation surface combining with material mapping method to realize the flowing surface with the effects of reflection and refraction.When it is used in environment representation such as the outdoor scene,it will make the surface more real,less computational complexity and designing and implementation more simple and convenient. |
