| def quadtree.Quadtree.__init__ | ( | self, | ||
| grid, | ||||
| measure, | ||||
| threshold | ||||
| ) |
Constructs a new Quadtree from a grid.
Measure is a class that implements two methods, as in the example below. Threshold is a value between 0 and 1; a node is not split when the detail of that tree section is less than the threshold.
