基于VRML技术的虚拟实验室的设计与实现

摘要

虚拟实验有助于提高学生的自主学习兴趣、创新能力、实际动手能力和综合素质.针对实验教学的特点,对基于VRML技术的虚拟实验系统进行功能分析和结构设计,并对虚拟模型的建立和优化、虚拟实验中的交互以及交互过程中对数据库的访问等关键技术进行研究.实践证明,基于VRML的虚拟实验系统是切实有效的.%The virtual experiment can improve students' interest in independent learning, innovative ability,practical ability and compositive diathesis. According to the characteristics of experimental teaching in network, the functional analysis and the structural design of virtual experimental system based on VRML are carried on. Besides, many key technologies are studied, such as the establishment and optimization of virtual model, the interaction of virtual experiment, the database visit in interactive process. The results show that it is valid and effective.
