面向VR系统的三维场景的建立和导入

The Creation and Import of 3D Scene on VR System

虚拟现实领域离不开三维大规模场景的建立,而场景的建立又与3Dmax、Maya等基础的三维建模工具密不可分。本文所阐述的三维场景模型均是基于3Dmax建立的基础模型。三维大规模场景的建立和编辑过程分为两种:一种是单个导出模型,在导入场景编辑器进行整体编辑,最终生成整个场景文件供程序调用(以在irrlicht中应用为例);另一种是直接导出经转换可供程序使用的整个场景文件(以在ogre中应用为例)。做好三维场景的编辑和导入工作有利于增强虚拟现实场景的真实感。

The field of virtual reality is inseparable from the building of large scale three dimensional scenes, and the building of 3D scenes has a close relationship with basic 3D building tools such as 3Dmax ,Maya and so on. The models used in the scene are all built by 3Dmax.There are two kinds of process for building and editing the large scaled 3D scenes. One process is that we export models separately, and then import them into a scene editor to conduct an overall scene file. We will take this kind of use in irrlicht for example. Another one is directly export the entire file after some conversion process, taking the use in ogre for example. The better we do with the work of editing and importing for 3D scenes, the more realistic the VR scene will be.
