NonHierarchicalViewBasedAlgorithm

open class NonHierarchicalViewBasedAlgorithm<T : ClusterItem?> : NonHierarchicalDistanceBasedAlgorithm<T> , ScreenBasedAlgorithm<T>

This algorithm works the same way as NonHierarchicalDistanceBasedAlgorithm but works, only in visible area. It requires to be reclustered on camera movement because clustering is done only for visible area.
