摘要
目前单一的实景建模技术往往无法满足天然气场站的建模需要,同时这种小范围、设备数量庞大的三维场景也考验着地图加载引擎。分析了行业主流的建模技术特点及其适用性,采用多技术融合的方式完成天然气场站精细化建模;梳理Cesium所支持的三维数据格式glTF和3D Tiles,3D Tiles在继承gl TF网络快速传输优点的同时,还具备HLOD特性,使得三维可视化加载更为流畅;利用Cesium前端框架搭建了天然气场站三维可视化场景,从远、中、近距离均可流畅渲染模型。结果表明,多技术融合的方式能够实现天然气场站的精细化建模,基于Cesium搭建的三维可视化场景能够满足天然气场站业务需求。
At present,a single real scene modeling technology often can not meet the modeling needs of natural gas stations.At the same time,this small-scale and large number of equipment 3D scene also tests the map loading engine.The characteristics and applicability of mainstream modeling techniques in the industry are analyzed,and the refined modeling of natural gas station is completed by means of multi-technology fusion.The 3D data formats glTF and 3D Tiles supported by Cesium are reviewed.3D Tiles not only inherit the advantages of glTF network for fast transmission,but also have the HLOD feature,which makes 3d visual loading more smooth.Cesium front-end frame is used to build a 3D visualization scene of natural gas station,and the model can be smoothly rendered from far,medium and close range.The results show that the method of multi-technology integration can realize the fine modeling of natural gas station,and the 3D visualization scene built based on Cesium can meet the business needs of natural gas station.
