先看官网的apiEntity - Cesium Documentation

这些都是属性。

看官网的代码创建实体 – Cesium

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

const wyoming = viewer.entities.add({
  polygon: {
    hierarchy: Cesium.Cartesian3.fromDegreesArray([
      -109.080842, 45.002073, -105.91517, 45.002073, -104.058488, 44.996596,
      -104.053011, 43.002989, -104.053011, 41.003906, -105.728954, 40.998429,
      -107.919731, 41.003906, -109.04798, 40.998429, -111.047063, 40.998429,
      -111.047063, 42.000709, -111.047063, 44.476286, -111.05254, 45.002073,
    ]),
    height: 0,
    material: Cesium.Color.RED.withAlpha(0.5),
    outline: true,
    outlineColor: Cesium.Color.BLACK,
  },
});

viewer.zoomTo(wyoming);

const redEllipse = viewer.entities.add({
  position: Cesium.Cartesian3.fromDegrees(-103.0, 40.0),
  name: "Red ellipse on surface",
  ellipse: {
    semiMinorAxis: 250000.0,
    semiMajorAxis: 400000.0,
    material: Cesium.Color.RED.withAlpha(0.5)
