I've been considering that too but it seems that the looping is disabled when you are building you own geoalgorithms.
I guess it has to to with that looping the Voronoi algorithm would result in an unknown number of seperate voronoi polygon layers (one per building). And working manually ending up with many thousand polygon layers (one for each building) in a whole town would be quite cumbersome I think ;-) ----- Regards Morten Qgis 1.8.0 Stand alone installer in Win7 64 bit -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Any-ideas-Splitting-polygons-to-only-have-one-point-in-each-polygon-tp5034081p5034110.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
