具有协同交流功能的虚拟物理实验室

Cooperate and Communicate Virtual Laboratory of Physics

为解决虚拟实验中师生不能有效交流的问题,采用VRML-JS-Java通信机制实现了一种具有交流功能的虚拟物理实验室.介绍了实验室总体设计和场景层次结构,阐述了三维场景的建模过程和流程,重点对交互功能的服务器端、客户端、用户间的交互与感知,以及VRML虚拟场景与Java接口等关键技术进行实现.经过发布与测试,表明虚拟物理实验室具有良好的层次性、可重用性和互操作性,在大学实验教学改革中具有较高的实用价值.

In order to solve the problem that teachers and students cannot communicate effectively in virtual experiment,this study uses VRML-JS-Java communication mechanism to realize a virtual physics laboratory. Firstly, the paper introduces the overall design and scene hierarchy of the laboratory. Secondly, it expounds the modeling process and process of three-dimensional scene, and focuses on the realization of the interaction and perception among server, client,and user of interactive function, as well as key technologies such as VRML virtual scene and Java interface. Finally, the experiments show that the virtual physics laboratory has good reusability and interoperability in university experimental teaching.
