The convex hull of a set of points is the smallest convex set that contains the points. This article presents a practical convex hull algorithm that combines the two-dimensional Quickhull algorithm with the general-dimension Beneath-Beyond Algorithm. It is similar to the randomized, incremental alg...
► Parallel Algorithm for constructing the convex hull of a set of points in 3D using CUDA. ► It is based on the QuickHull approach. ► Our implementation is 30–40 times faster that the CPU-based Qhull implementation. Introduction For a given set of points, S, in Rd, the convex ...
Barber, Dobkin, and Huhdanpaa (1996) proposed the Quickhull algorithm, which is a versatile solution that combines the two-dimensional Quickhull approach with the general-dimension Beneath-Beyond Algorithm, enabling high-dimensional convex hull computation. Antol, Jánošová, and Dohnal (2021) ...

Our convex hull algorithm of choice is Quickhull. Our parallel Quickhull implementation (for both 2D and 3D cases) achieves an order of magnitude speedup over standard computational geometry libraries.doi:http://hgpu.org/?p=6945Stanley Tzeng...
In the TBB distribution, look in directory examples/parallel_reduce/convex_hull/ for a complete QuickHull algorithm that does speed up. It uses parallel_reduce (not parallel_for) to do the top-level partitioning. It does use and concurrent_vector, but batches up points before copy...

With the help of duality the inner and outer polygon can be determined easily. This as well as the convex hull algorithm fromMatlab[18] was used in the improved method of Beyramysoltan et. al. [5]. In our method we assume that the inner and outer polygons have already been calculated...
