`代码同前文；加载不同的数据，都不能加载出来；

var palaceTileset = new Cesium.Cesium3DTileset({
//url: './SampleData/Cesium3DTiles/Classification/Photogrammetry/tileset.json'
//url: './SampleData/Cesium3DTiles/Batched/BatchedColors/tileset.json'
//url: './SampleData/Cesium3DTiles/PointCloud/PointCloudConstantColor/tileset.json'
url: './SampleData/Cesium3DTiles/Tilesets/Tileset/tileset.json'
//url: './SampleData/Cesium3DTiles/Tilesets/Tileset/parent.b3dm'
//或者url: 'http://ip:port/www/DAEPalace/tileset.json'
});

然后更改代码为如下；

<script>
      

var viewer = new Cesium.Viewer("cesiumContainer");
 
var tileset = window.viewer.scene.primitives.add(
      new Cesium.Cesium3DTileset({
         //url: './SampleData/Cesium3DTiles/Classification/Photogrammetry/tileset.json'
         //url: './SampleData/Cesium3DTiles/Batched/BatchedColors/tileset.json'
         //url: './SampleData/Cesium3DTiles/PointCloud/PointCloudConstantColor/tileset.json'
         url: './SampleData/Cesium3DTiles/Tilesets/Tileset/tileset.json'
       })
     )
     tileset.readyPromise
      .then(function() {
         var boundingSphere = tileset.boundingSphere
         window.viewer.camera.viewBoundingSphere(boundingSphere, new Cesium.HeadingPitchRange(0.0, -0.5, 

boundingSphere.radius))
       window.viewer.camera.lookAtTransform(Cesium.Matrix4.IDENTITY)
      })
      .otherwise(function(error) {
        throw error
      })
 
</script>

然后3D Tiles数据加载出来了；下面是不同的3D Tiles数据；

不同的3D Tiles数据；

都能加载；只有点云的那个不显示；

把自己的3D数据转换为它的3D Tiles数据，应该就能加载了；网上查转换工具；
