摘要
HTML5、WebGL、云渲染等技术为浏览器、移动端、XR等多种终端的可视化渲染提供了重要技术支撑。本文分析比较了其优缺点,并采用虚幻引擎4的云渲染技术,采用某煤矿的倾斜摄影、BIM、巷道、设备、三维地质模型开展了系统设计与测试,分析了云渲染的效率和效果,实现了数字孪生云渲染技术在智能矿山的应用。
HTML5,WebGL,cloud rendering and other technologies provide the important technical supports for 3D rendering of various terminals such as browsers,mobile and XR terminals.After analyzing the advantages and disadvantages of the above technologies,a digital twin platform of the intelligent mine is proposed,with cloud rendering technology using unreal engine 4.The system is designed and verified by using oblique photogrammetry data,building information model,3D roadway models and geological 3D models.The efficiency and effect of cloud rendering are analyzed,and the digital twin cloud rendering technology of intelligent mines is explored.
