Minkowski Sum Construction and other Applications of Arrangements: and the Importance of Being Exact,Used
Delivery time: 8-12 business days (International)
We present two exact implementations of efficient outputsensitive algorithms that compute Minkowski sums of two convex polytopes in threedimensional space. We do not assume general position. Namely, we handle degenerate input and produce exact results. We provide a tight bound on the exact maximum complexity of Minkowski sums of convex polytopes in the space in terms of the number of facets of the summands. The complexity of Minkowski sum structures is directly related to the time consumption of our Minkowski sum constructions, as they are output sensitive. The algorithms employ a data structure that represents arrangements embedded on twodimensional parametric surfaces in the space and make use of many operations applied to arrangements. We also present an exact implementations an efficient algorithm that partitions an assembly of polytopes in the space with two hands using infinite translations. This application makes extensive use of Minkowskisum constructions and other operations on arrangements of geodesic arcs embedded on the sphere. It distinctly shows the importance of exact computation, as imprecise computation might result with dismissal of valid partitioningmotions.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
