This post evolved from previous discussion named "bbox strategy and zooming"
Clustering features with cluster strategy takes some time. If there are many features to cluster, it will take even more time :) So there are some scenarios where clustering shouldnt be recalculated. Example: I want to see my cluster layer only after 5th zoom level. No clustering should be made when i play on zoom level 0-4 with other layers, because it slows things down, and the cluster layer is still not visible at all (its only clustering features in background) It should only cluster when layer is visible (and the current map resolution is inside array resolution of clustered layer, if we define seperate set of resolution) So if map has: resolutions: [0,1,2,3,4,5,6,7,8,9] and vector layer: resolutions: [5, 6, 7, 8, 9] clustering should occur only on vector layers resolution :5, 6, 7, 8 and 9. I hope you see where im pointing now, Best regards, -- Ivan Grcic _______________________________________________ Dev mailing list Dev@openlayers.org http://openlayers.org/mailman/listinfo/dev
