摘　　要：针对基于PC的工程图学虚拟模型库在便携性方面的限制,论文对应用于移动端的工程图学虚拟模型库进行了研究。以Android操作系统作为虚拟模型库的开发平台、LibGDX为虚拟模型库开发的技术框架,通过分析系统的功能需求,确定了软件的系统框架。通过分析LibGDX的功能接口以及三维模型的数据格式,设计了虚拟模型加载器与缓存机制.基于LibGDX良好的渲染特性,设计了三维模型的解析类与渲染类,设计了软件的交互界面与核心功能模块,实现在移动端多角度展示三维模型及其对应二维模型的功能,从而实现基于Android操作系统的工程图学虚拟模型库的设计.A virtual model library of engineering graphics is established to solve the problem of the time and space limit to the use of existing virtual model library based on pc.The Android operating system is used as the development platform,and the LibGDX is used as the technical framework for the virtual model library.By analyzing the functional requirements of the system,the software system framework is determined.By analyzing the function interface of LibGDX and the data format of the 3D model,the virtual model loader and caching mechanism are designed.Due to the good rendering properties of LibGDX,the analytic classes and render classes of 3D models are designed.The interactive interface and the core function module of the software are designed,so as to realize the virtual model library of engineering graphics based on mobile device of the Android operating system.
