如何在铯中定义图块的位置

Question

我正在尝试使用铯3d tileset。但是我没有找到放置磁贴的方法。

我尝试在tileet.json中转换和限制体积，但这没用。

{
  "asset": {
    "version": "1.0"
  },
  "properties": {
    "Height": {
      "minimum": 20,
      "maximum": 20
    }
  },
  "geometricError": 70,
  "root": {
    "refine": "ADD",
    "transform": [
        1.0001,0,0,
        0,1,0,0,
        0,0,1,0,
        0,0,0,1
  ],
  "boundingVolume": {
    "region": [
  -1.3197004795898053,
        0.6988582109,
        -1.3196595204101946,
        0.6988897891,
        0,
        30
      ]
    },
    "geometricError": 0,
    "content": {
      "uri": "instancedOrientation.i3dm"
    }
  }
}

我发现了如何在铯中放置磁贴。 只需在转换矩阵中更改翻译

tileset = cviewer.scene.primitives.add(new Cesium.Cesium3DTileset({
        url : url
}));

//Original location of tileset
let pos = {
    x: 1214939.1184933728,
    y: -4736505.884059093,
    z: 4081598.457967,
};

tileset._root.transform[12] = cviewer.camera.position.x - pos.x;
tileset._root.transform[13] = cviewer.camera.position.y - pos.y;
tileset._root.transform[14] = cviewer.camera.position.z - pos.z;
