以某大型景观湖为例, 研制了大型景观湖仿真演示系统。系统包括景观仿真和水利设施仿真。采用虚拟现实 和Virto ols 仿真技术, 构建了湖区三维虚拟现实场景, 制作了重点区域景观视频, 实现了湖区全景仿真和重点区域 仿真; 采用三维动画技术, 制作了闸门和防渗墙三维动画, 实现了水利设施仿真。景观湖仿真演示系统可服务于景 观湖工程运行管理, 全面介绍景观湖, 再现景观湖周边的美丽景观, 展示重要水利设施的功能。研究成果对类似大 型景观湖仿真演示系统的建设具有指导意义。

A simulatio n demo system of a larg e2scale landscape lake has been developed. The sy stem includes the landsca pe and water facility simulations. In or der to r ealize the simulations of pano ramic view and key ar eas, the three2dimensional virtual real2 ity environment of the lake and landscape video of the key areas have been develo ped using the v irtual r eality techno lo gy and Virto ols simulation techno lo gy . T hr ee2dimensional animation techno lo gy is used to make the simulat ion animat ions o f sluice gat e and diaphr agm w all in or der to realize the simulation demo of w ater facilit y. T he simulation demo system of landscape lake has multiple funct ions, such as ser ving the operation manag ement, int roducing the landsca pe lake comprehensiv ely , recreating the beautiful landscape aro und the lake, and showing the key functio ns of the water facility. T he st udy results ar e helpful fo r the co nstr uction of simulat ion demo sy stem of similar larg e2scale landscape lakes.
