【摘要】 本文简述了水体仿真的应用领域、特性及建模方法,并以虚拟系统中的瀑布仿真为例,为满足虚拟场景对真实性和实时性的需求,提出替代式的建模方式。文中阐述了替代式仿真构建的全过程,并通过多案例对比证实替代式建模方式的可行性和优越性。以替代式建模方法作为构建瀑布场景的主要方式,即用简单模型结合纹理贴图、粒子效果等形式替代复杂模型,在确保仿真效果的同时将复杂模型用最简化的方式表现出来,使虚拟场景在真实性和实时性两个方面都得到很好地表现。更多还原

【Abstract】 This paper describes the application field,characteristic and modeling method of water system virtual simulation,take the waterfall simulation in virtual system for example,propose the substitutional modeling to meet the demand for authenticity and real-time in virtual scene.This paper describes the entire process of constructing an substitutional simulation scene,by comparing multiple cases comfirmed the feasibility and superiority of substitutional modeling way. Substitutional modeling approach as the main way to build the waterfall scene, use simple model combined with texture mapping, particle effects forms alternative complex models, use simplified manner to shown complex model at the same time ensure the simulation results, make the virtual scene get good performance both in the authenticity and real-time.更多还原
