訪問tileset.json,查看root.transform,12,13,14分別代表模型參考原點的地心坐標Cartesian3(x,y,z)
let tileset = await Cesium.Cesium3DTileset.fromUrl()
構造origin_cartesian3=new Cesium.Cartesian3(x,y,z)
設置待平移到的位置經緯高為longitude,latitude,height,例如(116,39,0),單位是角度,則
target_cartesian3 = Cesium.Cartesian3.fromDegrees(longitude,latitude,height)let translation = Cesium.Cartesian3.subtract(target_cartesian3,origin_cartesian3,new Cesium.Cartesian3())tileset.modelMatrix = Cesium.Matrix4.fromTranslation(translation)
)
