摘要
运用AR技术研究解决传统课堂教学中难以学习理解的复杂结构问题,通过使用3D MAX、Blender等建模工具,选择支持多类型移动终端的Vuforia SDK作为AR开发框架,借助Photon分布式计算解决方案,通过Unity3D图形编程控制,开发一款既支持线上互动演示教学又方便学生线下自学复习的App软件。教师通过移动终端对叠加在现实背景上的3D模型进行缩放旋转与画笔勾勒等操作,用沉浸式体验增强学生的立体感,将复杂结构全方位讲述清晰,改革传统教学手段,有效提升学习效率。
In the traditional classroom teaching,it is difficult for teachers to explain clearly and difficultly for students to understand the complex structure.By using 3D MAX,Blender and other modeling tools,Vuforia SDK,which supports multiple types of mobile terminals,is selected as AR development framework.With the help of Photon distributed computing solution and Unity 3D graphic programming control,an App is developed.It not only supports online interactive demonstration teaching,but also facilitates students'offline self-study and review.By using mobile terminals,teachers can scale and rotate the 3D model superimposed on the realistic background and sketch the brush.With immersive experience,students'sense of substitution can be enhanced,and the complex structure can be described clearly in an all-round way.Thus,it reforms the traditional teaching methods and effectively improves the learning efficiency.
