javascript - Openlayers 3 Cluster by polygons -

i wonder clustering point delimit polygons.

i know how cluster don't know how not mix points not in same polygones. polygons stocked in geojson

i can't post comments yet, wondering meant 'delimit polygons'?

do mean have source has both points , polygons , want cluster polygons? or not want cluster polygons , cluster points?

openlayers 3.15 clustersource has option called geometryfunction allows cluster geometry shape. @ answer @ openlayers 3 , clustering polygons or linestings
