放大缩小地图,可以发现有些label上面没有billboard,但其实他们应该同时出现,根据聚类数量判断应该是label出现过早

What is Expected?

label和pooint、billboard出现和消失的时机应该一样并且符合聚类数量统计

What is actually happening?

有时候label会单独出现,而billboard则不会

跟了一下暂时没找到原因,
你也可以尝试分析一下源码看看。

你空了测测实体有这个问题没。我对比了聚合代码,就是参考
https://github.com/CesiumGS/cesium/blob/main/packages/engine/Source/DataSources/EntityCluster.js
改的,聚合逻辑是一样的,可能原因在渲染上。

嗯,着急先用实体吧,图元的找到原因了再说。我看实体的聚合代码,用的也是primitive api。
