Abstract
Two typical approaches to robust geometric algorithms are applied to the construction of the three-dimensional convex hull, and their performances are measured by experiments. One of them is the topology-oriented approach and the other is the exact arithmetic approach accompanied with the symbolic perturbation and the floating-point acceleration. The merits and demerits of the two approaches were investigated by computational experiments.KeywordsConvex HullConvex PolyhedronParallel EdgeEdge GraphBlue EdgeThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
