面向师生共建的手机App 3D模型库研究与实现

Research and Implementation of Mobile App 3D Model Library Towards Teacher and Student Co-construction

针对PC工程图学模型库便携性受限的问题,提出基于手机App构建工程图学3D虚拟模型库。介绍了3D模型库的设计思路和关键技术,轻松实现对3D模型的旋转、平移、缩放、剖视、标记、装配等实时交互操作。通过师生共建3D模型库,激发了学生的学习积极性和主动性,提升了学生的图形思维,有效培养了学生的自主学习能力、创造能力和协作能力,为高校打造一流工程图学课程奠定了基础。

In view of the portability limitation of PC model library, based on the mobile phone App, it is proposed to build a 3D virtual model library of engineering graphics.The design idea, and key technologies are introduced, which easily realizes real-time interactive operations such as rotation, translation, enlargement, reduction, section mark and assembly of the three-dimensional model by users. Through the expansion of the model library, the enthusiasm and initiative of students are stimulated, and students’ graphic thinking is improved, which effectively cultivates students’ independent learning ability,creative ability and collaboration ability, thus lays the foundation for the continuous construction of the first-class engineering graphics course in universities and colleges.
