Minkowski Sums of Set-theoretic Models
This paper describes a new algorithm for computing Min-kowski sums of set-theoretic geometric models. The algorithm uses a variation on Woodwark's method for feature recognition. At the end of the paper we present results from an implementation of the algorithm running on two-dimensional data, and from a more experimental version ray-tracing into three-dimensional Minkowski sums to render a pic...
متن کاملApproximating Minimum Steiner Point Trees in Minkowski
Given a set of points, we define a minimum Steiner point tree to be a tree interconnecting these points and possibly some additional points such that the length of every edge is at most 1 and the number of additional points is minimized. We propose using Steiner minimal trees to approximate minimum Steiner point trees. It is shown that in arbitrary metric spaces this gives a performance differe...
متن کاملExploring feature set combinations for WSD
This paper explores the split of features sets in order to obtain better wsd systems through combinations of classifiers learned over each of the split feature sets. Our results show that only k-nn is able to profit from the combination of split features, and that simple voting is not enough for that. Instead we propose combining all k-nn subsystems where each of the k neighbors casts one vote....
متن کاملConstructing an interval of Minkowski space from a causal set
A criticism sometimes made of the causal set quantum gravity program is that there is no practical scheme for identifying manifoldlike causal sets and finding embeddings of them into manifolds. A computational method for constructing an approximate embedding of a small manifoldlike causal set into Minkowski space (or any spacetime that is approximately flat at short scales) is given, and tested...
متن کاملSampling Point-Set Implicits
We present a novel approach for point-set implicit surface sampling that is able to rapidly distribute particles over the surface of 3D objects. Our methods benefit from the inner structure of a MPU implicit to obtain a near-optimal initial distribution, with higher densities in areas of higher complexity. The adequate number of particles to effectively sample the surface is determined almost a...
