摘要
为了展示出虚拟校园在不同天气特效下的视景仿真效果,增加漫游系统的真实感和交互性,在以上海电子信息职业技术学院为原型构建的虚拟校园漫游系统的基础上,利用Vega的API函数、粒子系统等方法实现了校园在不同天气特效下的视景仿真效果。尤其是难于模拟的雨雪特效,通过对雨雪粒子模型的属性分析,成功的实现了虚拟校园场景充满雨雪特效,使得系统有着良好的仿真效果。
In order to show visual simulation for the different weather special effects of virtual campus,and improve the reality and reactivity of roam system,bases on virtual campus roam system of Shanghai Technical Institute of Electronics and Information,scene simulation effects of different weather special effects is realized by Vega＇s API function and particle system.By analysis of rain and snow particle model＇s property,the filling rain and snow special effects in virtual campus are implemented,which makes the simulation effect more actua1.
