WebPisces
This web-based interface to the Pisces program allows you to compute implicitly defined curves in the plane. You can choose from several pre-defined functions, and can modify their parameters and domains.
Build a Rainbow
How are rainbows formed? Why do they only occur when the sun is behind the observer? If the sun is low on the horizon, at what angle in the sky should we expect to see a rainbow? This laboratory, developed as part of the University of Minnesota Calculus Initiative , helps to answer these and other questions by examining a mathematical model of light passing through a water droplet.
QuasiTiler
Generate the famous Penrose tilings, or design your own nonperiodic tilings of the plane. In the process, you can select and visualize plane cross-sections of a lattice in anywhere from 3 up to 13 dimensions!

This page collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications. It contains brief descriptions of those applications and the geometric questions arising from them, as well as pointers to web pages on the applications themselves and on their geometric connections. This is largely organized by application but some major general techniques are also listed as topics. Suggestions for other applications and pointers are welcome.

5. Geometry Center (Science U)
The Science U geometry Center contains fun interactive exhibits, informative articles, and helpful lists of facts and formulas in geometry and related areas of mathematics.
http://www.scienceu.com/geometry
Welcome to the Geometry Center! Shapes, Patterns, Symmetry! You will find these themes everywhere in the Geometry Center. Browse through an exhibit, or jump right in and start experimenting! Triangle Tilings and Polyhedra Triangle Tiling is the process of taking many copies of a single triangle and laying them next to each other to fill an area. Experiment with the different patterns you can create with flat tiles, or see how you can make polyhedra out of bent triangles with the Symmetry and Tiling Symmetry is everywhere in art, nature and geometry! Learn about periodic and nonperiodic tilings. Watch animations explaining the 17 different kinds of wallpaper symmetry, or use to make your own patterns. Tetrahedral Puzzles
Did you know that all convex polyhedra can be decomposed (cut up) into tetrahedra? Tetrahedra are 3-dimensional pyramids with only four faces, the fewest faces possible for any polyhedron. Learn about tetrahedral decompositions by making your own tetrahedra puzzle pieces out of construction paper and put them together to make more complicated polyhedra.

These pages contain usenet clippings, web pointers, lecture notes, research excerpts, papers, abstracts, programs, problems, and other stuff related to discrete and computational geometry. Some of it is quite serious, but I hope much of it is also entertaining. The main criteria for adding something here are that it be geometrical (obviously) and that it not fit into my other geometry page, Geometry in Action , which is more devoted to applications and less to pure math. I also have another page on non-geometrical recreational math

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!

Endorsements
References Endorsements References N ATIVE AMERICAN GEOMETRY is a physical, proportional geometry that originates from the simple circle. A growing body of architectural and iconographic evidence from Native America suggests it was a relatively common tradition that has been practiced for at least two thousand years. This is the same type of geometry that was discovered and developed by the ancestors of many peoples in many places, from China to the Mediterranean Basin to the British Isles. Currently, it resides among the logo designers of Madison Avenue. Generally, it maintains a similar methodological structure to the Middle Eastern tradition of classical geometry that is limited to operations carried out by the compass and straightedge, or two sticks and a rope. In the anthropological world, there are generally two ways traditions come into being in any particular culture: diffusion or borrowing from another culture; and, independent invention or discovery. Did the geometry have a single source and diffuse around the world over a period of several millennia? Or is there something about it, like stone working techniques, that made it independently accessible to the human mind in diverse cultures and civilizations? Personally, I believe the geometry was discovered independently by widely disparate cultures. Why? Because this type of proportional geometry originates with the circle, one of the most popular and multi-cultural symbols in the human world. It is a shape that served as a foundation for countless domestic and ceremonial structures. Given the intimate relationship between the circle's radius and the hexagon, it is an argument I can live with, for now. This opinion does not exclude instances of cultural diffusion within specific geographic regions.
