A Performance Comparison of Three Algorithms for Proximity Queries Relative to Convex Polyhedra
— This paper presents a comparative analysis relative to the experimental performances of an asymptotically fast and incremental algorithm, recently developed to compute collision translations for pairs of convex polyhedra. The algorithm may be worth considering because it solves a proximity problem which is less widely addressed than distance, as well as because of its peculiar computation strategy, well suited to work without initialization, but also endowed with an inherently embedded mechanism to exploit spatial coherence. Numerical data characterizing the behavior of the algorithm with respect to the complexity of the polyedra have already been discussed elsewhere, thus here the main focus is on contrasting its performances with those of two popular algorithms designed to compute distances between polyhedra. Although the considered “yardsticks” answer different proximity queries, and although one of the techniques is meant to deal with general polyhedra, the results presente...
