Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search Computational geometry is a branch of computer science devoted to the study of algorithms which can be stated in terms of geometry . Some purely geometrical problems arise out of the study of computational geometric algorithms, and such problems are also considered to be part of computational geometry. The main impetus for the development of computational geometry as a discipline was progress in computer graphics and computer-aided design and manufacturing ( CAD CAM ), but many problems in computational geometry are classical in nature, and may come from mathematical visualization Other important applications of computational geometry include robotics (motion planning and visibility problems), geographic information systems (GIS) (geometrical location and search, route planning), integrated circuit design (IC geometry design and verification), computer-aided engineering (CAE) (programming of numerically controlled (NC) machines). The main branches of computational geometry are: Combinatorial computational geometry , also called algorithmic geometry , which deals with geometric objects as discrete entities. A groundlaying book in the subject by Preparata and Shamos dates the first use of the term "computational geometry" in this sense by 1975.

In Chapter 13, we have included an extra section on binary space partition trees for low-density scenes, as an introduction to realistic input models. In addition, a large number of small and some larger errors have been corrected (see the list of errata for the second edition on the Web site). We have also updated the notes and comments of every chapter to include references to recent results and recent literature. We have tried not to change the numbering of sections and exercises, so that it should be possible for students in a course to still use the second edition.

Rob Kirby , a mathematics professor at Berkeley, recently published an open letter discussing the rising subscription prices of mathematics journals . Although he doesn't include them in his discussion, exactly the same issues apply to discrete mathematics and computer science journals. The annotations MathSciNet HBP Search ACM , and CSBib indicate bibliographies or search pages for the journal that are part of a larger bibliography collection. These annotations are explained on a separate web page . Most of these journals are also (at least partially) indexed in the Geometry Literature Database Upcoming special issues are listed on a separate web page DCG: Germany or New York (PDF, LaTeX)

Extractions: RPI The aim of this workshop is to bring together, in an informal setting conducive to stimulate collaboration, researchers from academia and industry, as well as students working in Computational Geometry and Geometric Applications. The goal is to learn from each other of recent progress on problems of common interest, leaving sufficient time for discussions and posing of new problems emerging from on-going research. Topics of interest span all algorithmic aspects of geometrical problems, either classical or emerging from applied computational areas, including but not limited to: Algorithmic methods in geometry Animation of geometric algorithms Applications of geometric algorithms Bio-geometry Combinatorial geometry Computer-aided design Computer graphics Computational metrology Computational statistics Computational topology Computer vision Experimental studies of geometric algorithms Geometric approximation algorithms Geometric computation in Computational biology Geometric data structures Geometry of geographic information systems Graph drawing Implementation issues for geometric algorithms I/O-scalable geometric algorithms Kinetic data structures Manufacturing applications of geometry Mesh generation Modeling new problems with geometry Motion generation, folding and unfolding

Extractions: Code This page lists "small" pieces of geometric software available on the Internet. Most of the software is available free of charge. Unless otherwise specified, C or C source code is available for all programs. Software libraries and collections and programs that can be run interactively over the web are listed on separate web pages. Caveat Surfor I can't make any claims about the usefulness or quality of the programs listed here. I don't have the time or equipment to try them all. If you have experience with any of these programs, either positive or negative, please tell me about it The programs on this page are divided into several categories, some of which are divided into further sub-categories. (Eventually, each category will get its own separate web page.) Each program is listed only once, but I've provided cross-links between overlapping categories, and I've tried to arrange similar categories near each other. Each category also includes links to relevant pages in Nina Amenta 's comprehensive Directory of Computational Geometry Software , which I strongly encourage you to visit!
