const viewer = new Cesium.Viewer("cesiumContainer");

const blueEllipsoid = viewer.entities.add({
  name: "蓝色椭球体",
  position: Cesium.Cartesian3.fromDegrees(-114.0, 40.0, 300000.0),
  ellipsoid: {
    radii: new Cesium.Cartesian3(200000.0, 200000.0, 300000.0),
    material: Cesium.Color.BLUE,
  },
});

const redSphere = viewer.entities.add({
  name: "带有黑色轮廓的红色球体",
  position: Cesium.Cartesian3.fromDegrees(-107.0, 40.0, 300000.0),
  ellipsoid: {
    radii: new Cesium.Cartesian3(300000.0, 300000.0, 300000.0),
    material: Cesium.Color.RED.withAlpha(0.5),
    outline: true,
    outlineColor: Cesium.Color.BLACK,
  },
});

const outlineOnly = viewer.entities.add({
  name: "黄色轮廓的椭球体",
  position: Cesium.Cartesian3.fromDegrees(-100.0, 40.0, 300000.0),
  ellipsoid: {
    radii: new Cesium.Cartesian3(200000.0, 200000.0, 300000.0),
    fill: false,
    outline: true,
    outlineColor: Cesium.Color.YELLOW,
    slicePartitions: 24,
    stackPartitions: 36,
  },
});

viewer.zoomTo(viewer.entities);

效果如下：
