Abstract
In order to realize the digital mapping of physical watersheds and water conservancy projects,this paper proposes multi-scale modeling and visual rendering technology solutions.It discusses multi-scale modeling technologies of UAV oblique photography,BIM,and 3D laser scanning,as well as visual rendering technologies of real-time rendering engine,multiple levels of detail processing,simulation rendering optimization.Taking the application of digital twin Xiajiang water conservancy project as a case,the visualization method of GIS and BIM is applied to divide the model data into hierarchies and achieve visual rendering.The visual model of Xiajiang water conservancy project at macro,local and micro levels is constructed,which realizes multi-temporal and all-element geographical spatial digital mapping of the project,effectively supporting the construction of upper-level intelligent business applications.The research can serve as a reference for the application of multi-scale modeling and visual rendering in the water conservancy industry.关键词
