cesium-定位到3DTiles对象

这里介绍一下在cesium中定位到某个具体3dTiles的方式

核心代码

    let tileset = viewer.scene.primitives.add(new Cesium.Cesium3DTileset({url: '../data/3dtiles/tianjie/tileset.json',modelMatrix: Cesium.Matrix4.fromArray([0.9972458032561666, 0.04372029028528979, 0.05991113506964879, 0,-0.03623787897545647, 0.9920229449104262, -0.12073646051879428, 0,-0.06471185374661931, 0.11823287609043515, 0.9908750491338749, 0,-663.0794944260269, 1211.490494620055, 2974.1003134818748, 1]),}));let model = tileset;/*** 模型定位*/function modelLocate(){viewer.flyTo(model, {offset : {heading : Cesium.Math.toRadians(120.0),//方向pitch : Cesium.Math.toRadians(-10),//倾斜角度range : 450}});}
