Class ContinuousZoomEuclideanCentroidAlgorithm
-
- All Implemented Interfaces:
-
com.google.maps.android.clustering.algo.Algorithm
public class ContinuousZoomEuclideanCentroidAlgorithm<T extends ClusterItem> extends CentroidNonHierarchicalDistanceBasedAlgorithm<T>
A variant of CentroidNonHierarchicalDistanceBasedAlgorithm that uses continuous zoom scaling and Euclidean distance for clustering.
This class overrides .getClusters to compute clusters with a zoom-dependent radius, while keeping the centroid-based cluster positions.

getClusters
Set<Cluster<T>> getClusters(Float zoom)
Returns clusters of items for the given zoom level, with cluster positions set to the centroid of their constituent items rather than the position of any single item.
- Parameters:
