访问tileset.json,查看root.transform,12,13,14分别代表模型参考原点的地心坐标Cartesian3(x,y,z)
let tileset = await Cesium.Cesium3DTileset.fromUrl()
构造origin_cartesian3=new Cesium.Cartesian3(x,y,z)
设置待平移到的位置经纬高为longitude,latitude,height,例如(116,39,0),单位是角度,则
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)
)
