This node creates Voronoi (Thiessen) polygons from the input point data according to the reference boundary. The input data for the reference boundary should be a Polygon or MultiPolygon.
The buffer distance with the provided unit is used to create dummy points that define a virtual boundary around the given reference boundary that controls the output of the Voronoi polygons. If the final Voronoi polygons are smaller than the given reference boundary, you might want to increase the buffer distance. For an illustration of the buffer distance see here.
