The question you asked about internal ray facet intersections on the stack exchange a while ago is something I've been referencing in conjunction with MATLAB's implementation of the quickhull ...
It generates a set of random points, calculates the convex hull using the Quickhull algorithm, and visualizes the result with matplotlib. The convex hull is the smallest convex polygon that encloses ...
Abstract: Skyline computation has been widely used in many research areas such as database visualization, data mining and multi-criteria decision. In this paper, we focus on a simple and effective ...
The complexity of QuickHull (the algorithm which you are asked to implement in Oblig 4) is O(n^2). The optimal complexity is O(n lg n). Graham's scan is optimal. An efficient parallel algorithm will ...
Our next example solves the planar convex hull problem: Given n points in a plane, find which of them lie on the perimeter of the smallest convex region that contains all points. This example shows ...
