Implementation Of 3D Model Library Based On The Android Framework By Using LibGDX

In recent years,smart phone has been developing rapidly and gained massive popularity,now it has become an indispensable portable devices in our daily life.At the same time,with the promotion of mobile terminal hardware,for the portability of mobile,more and more programs which has relevant needs turned the focus from the PC side to the mobile side.Considering the portability of showing 3D model on the mobile terminal,a virtual model library of engineering graphics based on mobile is established to solve the problem of the time and space limit to the use of existing virtual model library.After comparison,this system chooses the Android platform as the model library development platform,and uses the libGDX game development framework 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 interface function of the libGDX and the 3D model data format,the analytic classes and render classes of 3D models are designed,the virtual model loader and caching mechanism are designed.Designed interactive interface and the core function module of the software,realized the display function of the 3D model and its corresponding 2D image,so as to realize the virtual model library of engineering graphics based on mobile device of the android operating system.
