基于实时云渲染技术的数字孪生城市系统设计与实现
Design and implementation of a digital twin city system based on real-time cloud rendering technology
摘要
Abstract
The article addresses the issue of'heavy rendering but light analysis'in real-time cloud rendering technology within digital twin urban systems by proposing a cloud rendering collaborative architecture coupled with a Geographic Information System(GIS).This approach achieves an organic integration of spatial analysis functions and high-performance rendering capabilities.By integrating Unreal Engine(UE)Pixel Streaming push technology and WebSocket communication mechanisms,the system can dynamically fetch video streams generated by UE cloud rendering as dynamic basemaps,while overlaying interactive data dashboards to retrieve geospatial data in real time,forming a fusion visualization interface of'dynamic scenes+real-time data'.Taking the Nansha District of Guangzhou as an example,the study designed and developed a three-dimensional spatial foundation for the Nansha Pioneer Zone.Practical results demonstrate that this architecture supports real-time rendering of city-level models and highly reliable spatial analysis.关键词
