geometry - Max spread of multiple points -


i have group of points (x,y) , need find out distance between 2 farthest apart.

what efficient way find this?

thanks

well, compairing every point against every other point not efficient.

the efficient way involves finding convex hull, convex polygon (no angles > 180) surrounding points.

after that, find farthest points on hull, using antipodal pairs.

algorithm described here:
