Hello! Thanks for your library. I generate a series of poygons at random, and the polygons can be drawn on a widget with Qt. I can also output the vertexes with the function Item::toString. However, the number of bins that used is always zero, The result polygons' postion also haven't been changed. What the mistake I make. Here is the output info1 Here is the polygons I generate info2 Here is the screenshoot of code info3

Check the input, make sure that: all polygons are oriented clockwise and the first vertex is identical to the last vertex.
