We observe a somewhat surprising result: Given a set S of n points in E2 and a point q∉S, ⊖(n) time is sufficient to determine a point on the convex hull,�...
Feb 16, 2017 � The Qhull function that is supposed to give the closest facet only works if the point is inside the convex hull and not outside.
Feb 18, 2023 � The way to calculate the direction “away” is to find the nearest point in the hull, and then move some distance in the opposite direction.
