In the first part of the paper we solve the problem of detecting efficiently if a query simplex is collison-free among polyhedral obstacles. In order to solve this problem we develop new on-line data structures to detect intersections of query halfplanes with sets of lines and segments.In the second part we consider the nearest-neighbor problems. Given a set of n lines in 3-space, the shortest vertical segment between any pair of lines is found in randomized expected time O(n8/5+&egr;) for every &egr; 0. The longest connecting vertical segment is found in time O(n4/3+&egr;). The shortest connecting segment is found in time O(n5/3+&egr;).
