运行效果如下图：

示例代码如下：

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

const greenCylinder = viewer.entities.add({
  name: "带有黑色轮廓的绿色圆柱体(cylinder)",
  position: Cesium.Cartesian3.fromDegrees(-100.0, 40.0, 200000.0),
  cylinder: {
    length: 400000.0,//圆柱体长度，即我们看到的高度
    topRadius: 200000.0,//圆柱顶部半径
    bottomRadius: 200000.0,//圆柱底部半径
    material: Cesium.Color.GREEN.withAlpha(0.5),
    outline: true,
    outlineColor: Cesium.Color.BLACK,
  },
});

const redCone = viewer.entities.add({
  name: "红色圆锥(cone)",
  position: Cesium.Cartesian3.fromDegrees(-105.0, 40.0, 200000.0),
  cylinder: {
    length: 400000.0,//同上
    topRadius: 0.0,//顶部半径为0时，则变为圆锥
    bottomRadius: 200000.0,
    material: Cesium.Color.RED,
  },
});

viewer.zoomTo(viewer.entities);
