Data Types for Two-Dimensional GeometryThe kernels for two-dimensional geometry of LEDA provide points, lines, segments, rays, vectors, circles, polygons and generalized polygons. The following links lead to the corresponding manual pages for the floating point and the rational kernel.Floating Point KernelRational KernelTipUse the rational kernel exclusively ! Only when a program is stable and the rational kernel does not give the desired performance consider switching to the floating point kernel. A switch to the floating point kernel should be accompanied by a careful analysis of its limits. |
