【摘要】 本论文是在研究远程教学系统的基础上，针对其实验环节的薄弱性进行研究，运用虚拟现实技术设计实现了一套适合远程网络教学的虚拟实验系统。 本论文从网上虚拟实验系统的总体设计出发，提出了虚拟实验系统的组成模块。从研究虚拟场景的构建和用户对虚拟场景的交互技术出发，提出了对该系统的建模分类及建模方法。在运动建模中，提出了一种用来描述物体运动现象的方法，即用纹理映射法来描述物体的碰撞响应。以物理学实验为研究对象，对几种典型的物理现象进行建模，并提出了碰撞检测的算法。同时，在对交互性深入研究的基础上，提出了采用VRML和JAVA相结合，满足了用户对虚拟实验的交互要求。 该虚拟实验系统以三维建模语言VRML为核心，综合运用JAVA、Javascript和WEB技术，具有较强的先进性、实用性及跨平台性等特点，它弥补了网络教学中实验课的不足，是对传统远程网络教学的一个突破，具有一定的实用价值。更多还原

【Abstract】 On the basis of the study of remote education system, and aim at the weakness of its experiment link, the paper designs and realizes a virtue experiment system adapt to remote network education using virtue reality technique.From the collectivity design of the virtual experiment system based on internet, the paper proposes the composing module. From the study of the construction of virtue scene and the interactive technique of the user to the virtual scene, the paper proposes the modeling sort and modeling method of the system. In the movement modeling, the paper proposes a method used as describing the phenomenon of object movement, that is, using texture mapping method to describe the collision response of object. On the basis of using the physics experiment as study object, builds the modeling of a few of typical physical phenomenon, and proposes the arithmetic of collision measure. At the same time, on the basis of studying the interactive thoroughly, the paper proposes that make VRML and JAVA band together, fulfills the user’s interactive appeal to the virtual experiment.The virtual experiment system make the three- dimension modeling language VRML as the core, using JAVA, javascript and WEB technique synthetically, it has doughtily advanced capability, practicability, and multi-flat roof ability and so on, it makes up the insufficiency of the experiment curricula in the network education, and it is a breakthrough of traditional remote network education, and has a certain extent utility value.更多还原
