Question

产品: iclient3d for webgl  操作系统：win10 x64

聚合设置: 

const pixelRange = 10;
const minimumClusterSize = 2;
//启用集群
clusteringlayer.clustering.enabled = true;
//设置扩展屏幕空间边界框的像素范围。
clusteringlayer.clustering.pixelRange = pixelRange;
//可以群集的最小屏幕空间对象
clusteringlayer.clustering.minimumClusterSize = minimumClusterSize;
//将进行实体的广告牌聚类
clusteringlayer.clustering.clusterBillboards = true;
clusteringlayer.clustering.clusterLabels = true

 

     clusteringlayer.clustering.clusterEvent.addEventListener(
        function(clusteredEntities, cluster) {
          const entity = clusteredEntities[0];
          cluster.label.show = true;
          cluster.label.text = entity._label._text._value;
          cluster.label.font = '15px Microsoft Yahei';
          cluster.label.pixelOffset = new Cesium.Cartesian2(0, -50)
          cluster.billboard.show = true;
          cluster.billboard.scale = 2.0
          cluster.billboard.alignedAxis = Cesium.Cartesian3.ZERO
          cluster.billboard.width = 20
          cluster.billboard.height = 20
          cluster.billboard.id = cluster.label.id;
          cluster.billboard.verticalOrigin =
            Cesium.VerticalOrigin.BOTTOM;
          cluster.billboard.disableDepthTestDistance =
            Number.POSITIVE_INFINITY;
          cluster.billboard.image =
            entity._billboard._image._value;
        }
      );

如图上，已经设置了label和billboard聚合，但label文字总会叠在一起,如下图所示:

下图是没聚合的时候

你好，聚合entity时label聚合不了的问题可以参考博客：https://www.jianshu.com/p/99d2f9e2c83f
