Abstract: 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.

Key words: digital twin, cloud rending, intelligent mine, 3D engine, pixel streaming
