视景系统中三维动态模型加载方法的研究与实现

Study and Realization of Adding 3D Dynamic Models in Vision Simulation System

虚拟场景中如果缺少了三维动态表现,会影响到模拟的真实感和系统表现。基于OpenGVS开发平台提出两种动态模型的加载方法:(1)利用3DSMAX加载三维刚性物体运动过程;(2)加载使用底层图形库开发的动态效果,例如基于粒子系统的火焰等。同时,还对动态过程表现中要求的帧速稳定性提出了一种解决方案。上述方法无需过多资金投入,加入虚拟场景后耗费资源少,程序控制简单有效,实现效果逼真。

Lack of the 3D dynamic models will impact the performance of the virtual scene. Two methods of adding dynamic models into VR system were proposed based on the platform of OpenGVS as the followings: (1) Use 3DS MAX to add dynamic models of rigid objects ;(2).Add dynamic effects using OpenGL, including fire using particle system. A solution was also introduced which could make frame rate stable. The methods needn’t much fund support and occupy a little computing resource when added in the virtual scene.
