用于线上教学的工程图学虚拟现实交互模型平台

Virtual-Reality-Based Engineering Graphic Model System for Online Education

基于虚拟现实(VR)和增强现实(AR)技术,利用Unity 3D开发平台、3ds MAX、UV模型制作软件以及C#交互编程工具,开发了能够在手机终端和PC终端使用的适用于线上教学的工程图学虚拟现实交互模型平台.详细介绍了平台的底层设计、功能及技术开发方案、内容设计以及平台的管理策略.该平台可充分发挥VR和AR技术各自的优势,有利于克服工程图学课程线上教学在模型展示与交互方面的障碍,为工程图学课程的信息化建设提供了有益的尝试与探索.

In order to adapt to the online education tendency, an interactive engineering graphics model system was developed based on virtual reality （VR） technology and augmented reality （AR） technology, which could be used on both smart-phone and personal computer. This system was accomplished with the usage of Unity 3D platform, 3ds MAX, UV and C~. The underlying structure, function and technology solutions, content design and the management strategy of this system were described. It is a promising solution to the model display problem in the engineering graphics course, especially in online education. So this work is a beneficial exploration and try for the hybridization of engineering graphics education and modern information technology.
