摘要
淤地坝对水资源调控过程是一种动态变化的过程,只用文字描述,无法给研究人员形象直观的展示,本文提出一种基于Unity3D的降雨过程与淤地坝调控水资源过程的模拟方法。采用3DsMax对淤地坝系主要模型进行三维建模,使用Unity3D引擎进行场景交互设计,采用粒子系统进行降雨的模拟,设计并实现了水资源收集仿真算法,利用多层次细节技术和剔除遮挡技术等进行渲染优化。借助这一方法,开发了淤地坝水资源调控虚拟再现仿真系统。实例表明,该方法可以形象逼真的再现降雨径流过程,还能表现淤地坝等组件对于水资源的调控过程,使展示的效果更加逼真。
The regulation and control process of water resources by warping dams is a dynamic process,which can not be displayed visually and intuitively by researchers.This paper proposes a simulation method of rainfall process and warping dam regulating wa⁃ter resources process based on unity3d.3DsMax is used to model the main model of Warping Dam System in the scene,unity3d is used for scene interaction design,particle system is used for rainfall simulation,and simulation algorithm for water resource collec⁃tion is designed and implemented,and multi-level detail technology and occlusion removal technology are used for rendering opti⁃mization.With the help of this method,a virtual reappearance simulation system for water resources regulation of warping dams is developed.The example shows that the method can reproduce the rainfall runoff process vividly,and can also show the regulation process of warping dam and other components on water resources,which makes the display effect more realistic.
