介绍了Java3D 与VR 相结合的Web3D 应用；采用了三层式的Client/Server 结构和分布计算模型设计系统体系结构，提出了在Java3D 中获取场景对象实例的方法，给出了在Java3D 场景中实现虚拟场景中漫游的方法。采用Java3D 实现与用户交互虚拟三维场景，并给出了部分实现细节。[关键词]：Java3D；VRML；Web3D；虚拟场景；[Abstract]：This paper introduced the Web3D application with Java3D and VR, adopt the Client/Server structure and distributing computing model to design the system structure, put forward the method to catch the scene object instance and presented the wandering method to implement virtual scene in the Java3D scene. With Java3D, implement the interaction virtual 3DM scene with the user, and implement a part of detail.[Keyword]：Java3D；VRML；Web3D；Virtual Scene
