摘  要
 
 基于虚拟现实技术的网络学习环境主要是指利用虚拟现实技术构建一个模拟的学习环境，类似于虚拟校园与虚拟教室。采用3D建模技术构建一个虚拟学习环境，利用虚拟现实中VRML语言的特点，使该环境具有空间变换，增强它的真实感，以加强学习者在学习过程中的情感认知，使学习者有置身其中的感觉，以增强学习效果。
 文章对VRML 结合3DS MAX在网络教学中实现虚拟学习环境的技术进行了探索，并以实例的形式讨论了虚拟教学环境静态建模方法及教学过程中动态仿真等的关键技术问题。首先用相应的软件进行三维建模，突显出真实性；再结合VRML节点，实现更多的交互性，如信息提示、视频点播、声音控制等等，并尽可能的达到真实的教学环境的效果。
 该网络学习环境为教育技术的应用开辟了新的领域。

ABSTRACT

 The network learning environment which is based on the virtual reality technology means using virtual reality technology to build a simulated learning environment, similar to virtual campus and virtual classroom. In order to transform the environment space and enhance its realism, we use 3D modeling techniques to build a virtual learning environment and use virtual reality modeling language features. And thus it strengthens the learners’ emotional awareness in the learning process and makes them feel they were in real environment. So it enhances the learning effects.
 The article makes an exploration on using VRML combined with 3DS MAX to construct the virtual network learning environment and discusses the key technical problems in the form of examples on static modeling in the process of dynamic simulation in the virtual learning environment and teaching methods. First, use the corresponding three-dimensional modeling software to highlight the truth. Second, we combine with VRML nodes to achieve more interactive, such as information tips, video frequency broadcast, sound control, and so on, and as far as possible to achieve real teaching and learning environment results.
 The network learning environment for the application of educational technology has opened up new areas.
