OpenGL技术在虚拟现实三维重建中的应用

目前,利用专业三维建模软件很难实现虚拟现实所需要的交互性,同时,在OpenGL建立的虚拟现实环境中,也很难通过编程进行复杂的三维建模.因此通过研究比较现在常用的利用OpenGL创建3D模型的方法,提出了一种新方法,即利用3DSMax进行复杂建模,并将模型导出为3DS格式,然后通过在OpenGL下编程控制模型来达到对虚拟现实环境的仿真.最后,利用该方法成功模拟了一个交通事故现场的虚拟环境,并可以对环境中的车辆等事物进行编程控制.

Application OpenGL in 3D reconstruction of virtual reality

Now professional 3D modeling softwares can't meet the requirement of interactivity of a VR system,meanwhile,in the graphic developing environment based on OpenGL,it is difficult to create complicate 3D models by encoding.Therefore,a new method is put forward,that is,to create complicated models by using 3DSMax,the model files exported to 3DS-format and fetched in OpenGL in which real-time rendering effects is attainable.At last this method is used in a virtual reality system of a traffic accident scene succ...
