As curves of . curvature, ridges are relevant in a number of applications including surface segmentation, analysis, registration, matching. In spite of these interests, given a smooth surface, no algorithm reporting a certified approximation of its ridges was known so far, even f

In this paper, we study linear transformations of cubes and prisms using .-circulant matrices, where . is the direct product of cyclic groups. As application, we study the evolution of a single cell of an .-dimensional grid under t

Subdivision solvers are used for computing these points on the faces of the box, and segments joining these points are deduced to get a graph iso

Anmerkungen zu MuPAD Release 1.3,echniques reduce the problem to that of implicitization of planar curves. For space curves, which are described as the intersection of two implicitly defined surfaces, we show how to generate an approximately orthogonalized implicit representation. In the case of surfaces of revolution, we address t
