【摘要】 为了满足铸造CAE网络化应用需求，聚焦于铸件温度场可视化，研究基于ECMAScript2015(ES6)标准的本地文件访问、基于HTML5画布元素的绘图以及网格实体的计算机图形学等关键技术，开发了一套铸件温度场可视化的Web应用程序。该程序运行时，所有交互操作都在客户端完成，不需要后台支撑，更为重要的是，操作便捷的图形化工具按钮以及实时渲染的真实感网格实体可以带来优良的用户体验。更多还原

【Abstract】 In order to meet the increasing internet-based demand of foundry CAE, focused on the visualization of the casting temperature field, key techniques of local file access based on ECMAScript 2015(ES6) standards,drawing based on HTML5 canvas element and computer graphics related to mesh entities were investigated and a set of web application program for the visualization of the casting temperature field was developed.When the program ran, all interactive operations were completed on the client-side without server-side support, and more importantly, the convenient graphical tool buttons and real-time rendering realistic mesh entities could bring an excellent user experience.更多还原
