【摘要】 随着网络技术的发展和教学资源的扩大,改进和优化虚拟实验室体系结构,建立三维模型库,可以提高模型利用率并加快模型检索速度,实现虚拟教学资源的共享性和扩展性。初步探讨了基于网络模型库的虚拟实验室的体系结构,分析了三维模型库设计过程中需要考虑的几个问题,最后实现了一个简单的三维模型库原型系统,并应用在虚拟考察实验室中。更多还原

【Abstract】 With the development of network technology and the expansion of teaching resources.Improve and optimize virtual laboratory architecture can improve model utilization;speed up the model retrieval speed;reduce redundancy of teaching resources.However,there is less research on the three-dimension model database.This paper discusses the architecture of virtual laboratory based on web three-dimensional model library.Analyse several key issues in the design of 3D model databases.Finally a 3D model library prototype system is implemented and used in virtual field trips laboratory.更多还原
