【摘要】 实验是科学普及、高等教育和远程教育中不可缺少的一环,目前的实验基本上是在实验室中进行的,运作方式存在着投入大、损耗大、效率低、周期长、维护困难、危险性等缺点。在采用计算机技术实现的各种虚拟实验室中,实验者可以像在真实的环境中一样完成预定的实验项目,所取得的学习或训练效果等价于甚至优于在真实环境中所取得的效果。本文先介绍了当前国内外虚拟实验及虚拟实验室开发相关技术,对这些技术做了一些简要比较,接着论述了虚拟现实开发平台VIRTOOLS的概念、模组、特点和应用领域。然后结合课题“基于Web服务的可扩展建模与仿真技术理论基础研究”,提出了一种基于3D和VIRTOOLS技术的虚拟实验室开发方案,其中详细论述了虚拟实验的开发方法、虚拟实验数据分析处理解决途径和虚拟实验室的架构和功能模块的设计。最后应用该技术具体开发了一个中学物理实验仿真系统。实践证明,采用该技术开发的虚拟实验室具有减小开发难度、缩短开发周期、真实性好、交互性强等特点。本文在进行项目开发过程中,主要作了以下三个方面工作:(1)、提出了一种虚拟实验开发方法-VVE,即用3DMAX构建3D实验场景、制作3D动画,用VIRTOOLS进行数据处理,交互控制;(2)、根据常规实验数据处理方法,提出了两种虚拟实验数据处理方法,一种使用VIRTOOLS模块实现的数据处理,另一种使用JSP外部程序语言实现的数据处理;(3)、提出了一种虚拟实验室架构,并详细阐述了其中的功能模块及实现途径。最后,本文对开发项目作了一个总结,并对今后的工作发展作了展望。更多还原

【Abstract】 The experiment is an indispensable part of the popularization of science, the higher education and the distance education. Currently, most experiments are operated by students in the real laboratory, and this mode has some disadvantages such as large investment, wastage, low efficiency, long cycle, maintenance difficulties and dangers. By the virtual laboratory way, experiments can be completed the same tasks as those in a real laboratory, and the effects of learning or training are substitutable or even better than those obtained in a real environment.In this paper, the related development technologies of the virtual experiment and the virtual laboratory are firstly compared and introduced. A new development approach of virtual laboratory based on 3D and VIRTOOLS is proposed supported by the project—“Research on the basic theories of the extensible modeling and simulation based on Web service technologies”, of which, the methods of the experimentation data analysis, the design of architectures and the function modules are discussed in detail. Finally, a virtual lab of the high school physics experiment is developed. It is showed by practice that it can make the developments of virtual laboratories more simplification, and can improve the efficiency, the facticity and the interaction, etc.Some main contents for this project as the follows: (1) a new development approach of the virtual experiment based on 3D and VIRTOOLS technologies named VVE is proposed. Namely, the VVE constructs the 3D experiment scene and creates the 3D animation with 3DMAX, processes and interacts on the experiment data with VIRTOOLS; (2) two approaches of the virtual experimentation data disposal are discussed based on the ordinary experiment. Namely, one is programmed with BBS within VIRTOOLS, and the other one is exploited by the JSP technologies; (3) a new architecture of the virtual laboratory is proposed, and its function modules and realizing ways are illustrated in detail.At last, a summary and a prospect of this paper are given.更多还原
