三维仿真场景构建及漫游系统实现

The Construction of 3D Simulation Scene and Implementation of Roam System

采用视景仿真工具MultiGen Creator和Vega设计并开发了以武汉理工大学为原型的虚拟校园三维仿真漫游系统。三维仿真漫游系统的视觉效果及运动速度与虚拟校园三维场景构建中的多种关键技术相关,在建模中采用了纹理映射技术、LOD技术、布告板技术、减少多边形数量等等相关技术,在实时驱动漫游的过程中,采取了多种人机交互方式以及碰撞检测等等,由此最终实现了三维仿真漫游系统。

With the application of the development tools-MutiGen creator and Vega,a virtual campus 3D simulation system for WUHAN University of Technology is created.The system＇s vision effect and motion velocity are related with the key technologies of virtual campus＇s 3D scene modeling.The relevant techniques such as texture mapping,LOD,Billboards and the reduction of polygon＇s number are used in modeling while the man-machine interaction and collision detection are employed in real-time driving.At last,a 3D simulation system is developed.
