摘要： 在分析基于实景的虚拟现实场景建模特点的基础上,运用一个具体的实例来阐述了基于实景的虚拟现实场景的生成过程及其相关注意事项,通过合理建模减小复杂度、通过真实感贴图来增强逼真度、通过模型导入的对象化来实现对虚拟物体的控制。最终在逼真性、实时性和可控性方面都达到了较好的效果。

Abstract: This paper analyzes the characters of virtual reality scene modeling based on real scenery, applies an instance to expound the buildingprocess of a virtual reality scene based on real scenery, sets forth the relative notice items. Decrease the complexity degree by reasonable modeling;increase the fidelity by realistic texturing; realize the control on virtual objects by using object-oriented method in loading model. In the end, theresult can get to a better level in aspects of fidelity, real time and controllability.
