基于VRML技术虚拟机械设计实验室的研究

Study of the virtual machine design laboratory based on VRML technology

交互性有利于激发学生的学习兴趣和认知主体作用的发挥。虚拟实验室是依赖于计算机网络环境下的实验环境,其设计与应用有助于提高学生的学习兴趣和动手能力。基于虚拟现实构造语言(Virtual Reality Modeling Lan-guage,VRML)制作机械设计虚拟实验室具有交互性好、沉浸感强、制作和使用方便、能提高协作性特点。分析了基于VRML制作机械设计虚拟实验室的原因,对如何制作机械设计虚拟实验进行了分析探讨,论述了机械设计虚拟实验室的设计实现过程。利用VRML实现虚拟实验的多媒体教学系统,改变了教学环境的设计,有助于教学创新和提高教学效果。

Interaction is advantageous to arouse the student＇s learning interest and to develop the intention of cognition mainbody. The virtual laboratory is an experimental environment depending on the environment of computer network; its design and application are conducive to enhance the student＇s learning interest and ability of getting to work. The machine design virtual laboratory manufactured basing on VRML possesses good interactivity, strong sense of immersion, convenience in manufacturing and use and could increase the coordination. This paper analyzed the reason for the manufacturing of machine design virtual laboratory based on VRML. Analytical discussion has been carried out on how to make the virtual experiments of machine design, and the designing and realizing courses of the machine design virtual laboratory was expounded. By applying the VRML multi-media teaching system of realizing the virtual experiment that changed the design of teaching environment and is helpful for the teaching innovation and the enhancement of teaching effects.
