摘要
VR(Virtual Reality)技术已经成为影响CBT(Computer Based Teaching)的关键技术之一.基于VRML(Virtual Reality Modeling Language)的VR技术已经作为教育部现代教育技术的重要内容〔1〕.但在现实CBT课件中应用偏少.一个重要问题就在于有关教师包括部分开发人员对于复杂VRML建模感觉难度太大.本文首先分析了VRML的情景模拟教学特色,进而对基于几何、函数等计算的VRML建模技术进行了综合介绍和分析对比.对模型在基于VRML的情景教学中的运用做了简要说明.希望本文分析介绍的多策略VRML建模方法能促进VRML技术在CBT中的运用.
Virtual reality technology has been one of key technologies in the field of computerbased teaching （CBT）. VRML- based VR technology has been adopted by the Ministry of Education of China as advance content for modern education technology. Facing with the great difficulty of some of the teachers and courseware developers in modeling for VRML - based courseware in CBT, this paper analysis the characteristics of scenario simulation - based tutoring, ana- lyzes and compares computingbased modeling methods with some useful examples. The approaches using these models in building virtual teaching scene is also briefly described.
