cesium 多边形加粗的边框

polygon 加outline最多只能是1px,定义宽度得用polyline 

env_draw_polygon(options = {}) {

    let e = options.e;

    console.log('draw_polygon----3333', options);

    let defaultLocalName = options.defaultLocalName;

    let polygon_point_arr = e.gps;

    this.init();

    let color = options.e.color;

    console.log('111polygon_point_arr1', polygon_point_arr);

    colorMaterial = Cesium.Color.fromBytes(color.r, color.g, color.b, 200);

    if (defaultLocalName == e.classId) {

      colorMaterial = Cesium.Color.RED.withAlpha(0.9);

    }

    let centerGps = e.centerGps;

    if (polygon_point_arr.length >= 3) {

      let cartesianArr = [];

      polygon_point_arr.map(item => {

        cartesianArr.push(this.transformWGS84ToCartesian(item, 0));

      });

      // console.log(' e.id ---', cartesianArr);

      let MassifEntity = new Cesium.Entity({ id: e.id, idInfo: e.id ,classId:e.classId});

      MassifEntity.rgbColor=color

      MassifEntity.polygon = {

        hierarchy: new Cesium.CallbackProperty(() => {

          return new Cesium.PolygonHierarchy(cartesianArr);

        }, false),
