cesium加载gltf

在Cesium中加载glTF文件的方法可以使用以下代码：

const modelUri = "path/to/model.glb";

const position = Cesium.Cartesian3.fromDegrees(longitude, latitude, height);
const heading = Cesium.Math.toRadians(headingDegrees);
const pitch = Cesium.Math.toRadians(pitchDegrees);
const roll = Cesium.Math.toRadians(rollDegrees);

const hpr = new Cesium.HeadingPitchRoll(heading, pitch, roll);
const orientation = Cesium.Transforms.headingPitchRollQuaternion(position, hpr);

const entity = viewer.entities.add({
  name: "model",
  position: position,
  orientation: orientation,
  model: {
    uri: modelUri,
    minimumPixelSize: 128,
    maximumScale: 20000
  }
});

viewer.trackedEntity = entity;

以上代码中，`modelUri`是glTF文件的路径，`position`是模型的位置，`heading`、`pitch`、`roll`是模型的方向，`minimumPixelSize`是模型的最小像素尺寸，`maximumScale`是模型的最大缩放比例。通过以上代码，可以在Cesium中加载并显示glTF文件。<em>1</em><em>2</em><em>3</em>
