On the Number of Arrangements of Pseudolines
Given a simple arrangementof n pseudolines in the Euclidean plane, associate with line i the list i of the lines crossing i in the order of the crossings on line i. i = ( i 1; i 2;...

New Lower Bounds for Convex Hull Problems in Odd Dimensions
We show that in the worst case, (ndd=2e;1 +n logn) sidedness queries are required to determine whether the convex hull of n points in IRd is simplicial, or to determine the number ...

Linear Complexity Hexahedral Mesh Generation
We show that any simply connected (but not necessarily convex) polyhedron with an even number of quadrilateral sides can be partitioned into O(n) topological cubes, meeting face t...

Simple Traversal of a Subdivision Without Extra Storage
In this paper we show how to traverse a subdivision and to report all cells, edges and vertices, without making use of mark bits in the structure or a stack. We do this by perform...

Algorithmic Tolerances and Semantics in Data Exchange
Within industrial contexts, a common view of the level of confidence needed in CAD data transfer processes may be expressed as “1 don’t mind if the [CAD data- tmnsfer] algorit...
