cesium 自定义属性方法-526互联

  Cesium.Cesium3DTileset.prototype.setObjsColor = function (ids) {
    let currentStyle = this.style && this.style.style || {};
    this.style = new Cesium.Cesium3DTileStyle({
      ...currentStyle,
      color: {
        evaluateColor: function (feature) {
          console.log(feature.myId, feature._batchId, ids.includes(feature._batchId));
          if (ids.includes(feature._batchId)) {
            return Cesium.Color.RED;
          }
        }
      }
    })
  };

evaluateColor 方法会遍历场景中所有 Cesium3DTileset 对象，个人觉得性能比较差，还是自己控制比较高效
