摘要
虚拟现实是用计算机模拟的三维环境对现场真实环境进行的模拟仿真。本文以西北农林科技大学南校区为例,结合MultiGen Creator专业建模软件和VRP可视化仿真应用软件,详细探讨了创建虚拟场景和场景驱动过程中关键技术,设计并实现校园虚拟现实平台。实际运行表明,生动逼真的校园虚拟现实平台浏览速度快、仿真效果逼真,它不仅是一个三维数字地图,也是一个简单的GIS系统。本文涉及的技术对其他虚拟场景仿真系统开发、VR-GIS系统开发有着重要的参考价值。
Virtual reality is the conduct of the simulation on the real environment using the three-dimensional simulation technologies. In this paper, the South Campus of Northwest A＆F University is taken as test area, the professional modeling software, MuhiGen Creator and the visual simulation tool VRP are combined together for the construction of the campus virtual reality platform （CVRP）. Also, virtual scene-driven technologies are discussed and illustrated in detail in the course of design and realization of the CVRP. The result shows that the vivid realization of the CVRP can be run fast with realistic simulation results, which is not only a three-dimensional digital map, but also a simple GIS system. And, the VR-GIS system development technology can be taken as a useful reference to other virtual scene simulation system.
