Abstract: The virtual reality design method based on the 3DS MAX and Virtools and the production process of the whole three-dimensional virtual mall were introduced. 3DS Max was used to construct 3D model, then 3D animation was created. In the model construction, levels of detail technology combined with texture mapping were adopted. Not only save creation time of system, but also improve the real-time rendering speed of the scene. In the scene of interaction design, the system adopts the collision detection technology to ensure the real ramble effect，makes users feeling being personally on the scene.

摘要： 　    介绍了3DS Max结合Virtools tool开发工具的虚拟现实设计方法及整个三维虚拟商场的制作流程，采用３ＤＳ　Ｍａｘ构建３Ｄ模型，制作３Ｄ动画，在模型构建中，采用层次细节技术和纹理贴图技术相结合的方式，在节省创作时间的基础上，提高了场景的实时渲染速度。在场景的交互设计中，本系统利用碰撞检测技术来保证系统漫游的真实感，最终实现了具有沉浸感、现实感、交互感的商场漫游系统。
