WebJun 13, 2024 · If my mathematical intuition is correct, the farthest point from any of your points in your 100x100 space should be a vertex in the voronoi diagram (if you include edges around the edges of your space). So if you compute the diagram and then test every vertex of the diagram you should find the farthest point. Share Follow
