摘要
可视化模型是水利数字孪生平台的重要组成部分,其在Web端应用时,庞大的数据量、复杂的模型结构以及不适用的传输策略都会导致模型应用渲染延迟,研究梳理轻量化处理过程:模型构建、简化、格式转换、压缩传输、渲染优化和应用性能提升,及Edgebreaker压缩算法、粒子系统等关键技术,并在水文发展基地三维展示系统进行应用验证.
Abstract
Visual models are important components of hydraulic digital twin platforms.When applied on the Web,the large a-mount of data,complex model structure,and unsuitable transmission strategies can all lead to delays in model application ren-dering.This study organized and streamlined the lightweight processing steps:model construction,simplification,format conver-sion,compression and transmission,rendering optimization,and application performance enhancement,as well as key technolo-gies such as the Edgebreaker compression algorithm and particle systems,and applied them in the three-dimensional display system of the hydrological development base for validation.
