摘　　要：三维虚拟环境漫游是虚拟现实技术应用的基本方向之一,具有重要的研究意义与应用价值。基于成熟的游戏引擎技术,提出一个具有较强通用性和可扩展性的三维虚拟漫游系统开发框架,并从3D场景快速构建、3D场景实时绘制、高级视觉特效生成和基于物理的场景模拟等四个方面详细介绍了该框架的关键技术实现。通过对系统原型的测试表明,采用该开发框架所构建的三维虚拟漫游系统可在一般的普通主流PC机上达到较好的性能和表现效果。3D virtual walkthrough system is a fundamental direction of the application of virtual reality technology,and has great importance in computer science research and application value.In this paper,we propose a development framework for 3D walkthrough systems based on mature game engine technique with high universality and scalability.We present a detailed introduction on the implementation of the framework＇s key techniques from four aspects： the 3D scene fast construction,the 3D scene real-time rendering,the generation of advanced special effects,as well as the physics-based scene simulation.Tests on the prototype of this system show that the 3D virtual walkthrough system constructed with this development framework is able to achieve preferable performance and representation effect in common mainstream PCs.
