| // Public methods to compute Voronoi diagram of a set of points and segments. |
| // Coordinates of the points and of the endpoints of the segments should belong |
| // to the 32-bit signed integer range [-2^31, 2^31-1]. To use wider input |
| // coordinate range voronoi_builder configuration via coordinate type traits |
| // is required. |
| // Complexity - O(N*logN), memory usage - O(N), N - number of input objects. |
