基于OpenGL的建筑小区虚拟漫游系统的实现

Implementation of virtual walkthrough system of residential zone based on OpenGL

建筑小区虚拟漫游是虚拟现实技术的一种前景非常好的新兴技术领域,本文利用OpenGL图形库具有的强大三维渲染能力,提出了一个基于OpenGL的建筑小区虚拟漫游系统。该系统通过导入3D Studio MAX模型文件了建立三维场景;运用八叉树结构进行视域剔除实现场景漫游的实时性;最后通过鼠标控制实现建筑小区交互性漫游。

Virtual walkthrough of residential zone is an emerging technology field of Virtual Reality with well prospects. A virtual walkthrough system based on OPOnGL which has powerful rendering capacity is proposed in this paper. This system could create the 3D scenes through loading 3D Studio MAX datas realize the real--time performance of virtual scene walkthrough through View-Frustum Culling by Octree structure and realize interactive walkthrough of residential zone through mouse control finally.
