基于分布式虚拟技术的工程图学CAI探索与实践

Exploration and practice of engineering graphics CAI based on distributed VR

该文基于分布式虚拟技术,结合工程图学课程教学的特点,论述了在现代教育环境下的计算机辅助图学教学,提出了适用于网络化的计算机辅助图学教学框架体系和相关技术,开发了网络化的工程图学教学课件虚拟系统。该系统以虚拟技术为支撑,紧紧围绕图学教学的宗旨,综合利用了虚拟技术的各种开发工具和理论,具有虚拟现实系统的特点：沉浸感、交互性、构想。

With the boom of higher education and the rapid increase of students, traditional education has been facing a huge challenge. Based on the distributed virtual reality technology and the characteristics of engineering graphics teaching, the authors discuss the theory about computer aided graphics teaching, and put forward a frame system fitting network and related technology about it. Based on the virtual reality technology and aimed at the graphics teaching, the authors have developed an experimental virtual system, which has the general characters of virtual reality system, such as immersion, interaction, and imagination.
