FeatureReductionSelection
autocast
配置減少視圖中點要素數量的方法。默認情況下,此屬性為
null
,表示圖層視圖應繪製每個要素。有兩種類型的特征縮減:
selection
和cluster
。- Selection 僅適用於 SceneView 中的點,並涉及細化重疊特征,因此屏幕上沒有任何特征相交。
- FeatureReductionCluster在空間上對點進行分組MapView進入集群.每個集群的大小與集群內的特征數量成正比。
例子:
// clusters points based on their spatial proximity to other points layer.featureReduction = { type: "cluster", clusterRadius: 100 };
// thins features in the view layer.featureReduction = { type: "selection" };
