基于Three.js的在仿真中的可视化和拾取研究

Research on Pickup in Simulation Based on Three.js

当下前端技术日新月异,WebGL以其无需插件和硬件加速等特点迅速在web3D展示技术中走红,而封装了WebGL的Three.js更是为3D图形的高效展示提供了可能。基于web端的仿真软件也在蓬勃发展,针对传统的拾取方法不能很灵动直观拾取仿真过程中所需要的体、面、线、点,文章阐述了基于three.js的体、面、线、点的点选和框选的拾取研究,讲解了其设计思路和实现的方法,相对于传统的拾取方法,能更好的满足在仿真过程中的应用,尤其是非网格模型中线面的拾取。

With the rapid evolution of front-end technology,WebGL is rapidly gaining popularity in web3D display technology with its characteristics of no plug-ins and hardware acceleration,while encapsulating WebGL Three.js provides the possibility for efficient display of 3D graphics.Web-based simulation software is also booming,in view of the traditional pickup method can not be very dynamic and intuitive pick up the simulation process required body,face,line,point,this paper describes the three.js based on the body,face,line,point of the point selection and box selection of the pickup research,explained its design ideas and implementation methods,Compared with the traditional pickup method,it can better meet the application in the simulation process,especially the pickup of the midline of the non-grid model.
