| The work aims to develop an STL model viewer program based on Web, STLViewer, that rivals complex 3D graphics rendering in a OpenGL rendering context, to adapt to the networking trend of foundry CAE technology and meet the functional requirements of pre-processing module of foundry CAE system for the advanced rendering of STL models. Firstly, a single-page design scheme was selected by imitating the operation mode and interface style of the Windows desktop program. Then, the Visual Studio 2019 development platform was chosen, and the system interface was designed by HTML5, CSS3, and JavaScript technology. The STL model visualization techniques based on WebGL were deeply studied, and the various functional modules of STLViewer were developed according to the technical route of active model rendering based on the scene environment. The STLViewer was designed and implemented, which had good functional integrity and reasonable and efficient internal logical structure. Combined with implicit interactions and explicit interactions, STLViewer, which implemented the advanced rendering function of the STL model in the network environment, had features such as random access to local STL models, diversified interactions with the active model, intelligent tracking model posture, view animation presentation in multiple ways, and convenient operation on model export. As an STL model viewer program with excellent performance, STLViewer can not only assist user to make a reasonable plan for mesh slicing, but also bring excellent user experience, which has received good results in practical application. |
