A wealth of famous results distinguishes this family of sets (e.g. Brouwer's fixed-point theorem, the isoperimetric problems). This classification also includes the study of polygons and polyhedra, and frequently overlaps discrete mathematics and group theory; through piece-wise linear manifolds, it intersects topology.

To get an idea about the style and format, take a look at the Introduction or chapter 7 on Voronoi diagrams Computational geometry Computational geometry emerged from the field of algorithms design and analysis in the late 1970s. It has grown into a recognized discipline with its own journals, conferences, and a large community of active researchers. The success of the field as a research discipline can on the one hand be explained from the beauty of the problems studied and the solutions obtained, and, on the other hand, by the many application domains-computer graphics, geographic information systems (GIS), robotics, and others-in which geometric algorithms play a fundamental role. For many geometric problems the early algorithmic solutions were either slow or difficult to understand and implement. In recent years a number of new algorithmic techniques have been developed that improved and simplified many of the previous approaches. In this textbook we have tried to make these modern algorithmic solutions accessible to a large audience. The book has been written as a textbook for a course in computational geometry, but it can also be used for self study.

Calculations for Convex Bodies Introduction In this notebook several useful calculations are set up for studies of convex geometry. The original motivation for making the notebook was to study some properties of convex bodies of convex width, so some of the calculations are aimed at this problem. In particular, for that problem it is convenient to expand the important functions in Fourier series or spherical-harmonic series, depending on the dimension. Owing to these considerations, the notebook focuses on the relations among the following functions: The position function r (embedding the surface of a convex body K in R^2 or R^3 parametrically) The support function, which is H := r n , though usually expressed in terms of the angular coordinates of n , the normal vector to the supporting plane at r , rather than in terms of general parameters. The curvature. In this notebook, curvature will be described in terms of the principal radii of curvature; in 3 dimensions, in terms of the sum of the principal radii of curvature at r . As for the support function H, the curvature is often considered a function of the angular coordinates of
