Rotated-Box Trees: A Lightweight ,-Oriented Bounding-Volume Hierarchy ,We introduce a new type of bounding-volume hierarchy, the ., or .-.-tree for short. A .-.-tree uses boxes as bounding volumes, whose orientations come from a fixed set of predefined box orientations. We theoretically and experimentally compare our new .-.-tree to two existing bounding-volumes hierarchies, namely .-.-tree and box-trees.

Measuring the Similarity of Geometric Graphs,What does it mean for two geometric graphs to be similar? We propose a distance for geometric graphs that we show to be a metric, and that can be computed by solving an integer linear program. We also present experiments using a heuristic distance function.

Charlotte Holgersson,Britt ?stlundon computing a feasible solution of the linear program that is as far as possible from satisfying an inequality at equality. To realize such an approach, we have to detect the set of inequalities that can only be satisfied at equality..Compared to previous approaches for this problem our algorithm has a much higher rate of success.
