There's a explosion of interactive geometry software. In late 1990 came Cinderella, written in Java. In the 1990s, there's only Geometer's Sketchpad and Cabri Geometry. Triangle to change its shape, and all your drawings change accordingly.īecause of such dynamic power, a few theories on plane geometry have been The largest possible circle inside.) Now, you can drag the corners of your Point called the incenter of the triangle. For example,ĭraw a triangle with lines bisecting the 3 angles. Such program allows one to construct plane geometry drawingsĭynamically, much in the way of Greek's “Ruler and Compass”.

Interactive plane geometry software were made popular first by Geometer's You can drag the fixed points, the poles, andĪ few other critical points in the plane and see the image change as you If you are studying Mobius Transformation, this This Java applet does real-time interactive Hyperbolic Tesselations Applet draws hyperbolic tilings. Partial screenshot of Hyperbolic Tesselations Applet It does not let you drag and spin, but offers both multiple slice view and projection view on about 4 regular polyhedrons. HyperSpace 2.0 (1990) is another higher-dimensional polytope viewer, by Paul Bruke. Source Ishihama Yoshiaki's software are usually raw and unpolished. His programs are small and original, but the interface is very crude. Many of them are related to high dimensions, including a 4 and 5 dimensional Rubic cube simulators. HyperDimension 1999 Ishihama Yoshiaki has written several interesting programs. I don't have a copy of it.) HyperDimension The software downloaded from the ftp site is missing data files, making the software not usable. It is a rare tool for crystallographer and mathematicians. By the words of the authors: “… for interactively designing and systematically generating periodic 2-dimensional tilings and patterns, study symmetry and 2-dimensional geometry, if you are a mathematician, enumerate possible 2-dimensional crystal-structures, if you are a crystallographer or chemist, design complex and interesting patterns, if you are a designer, or explore a whole new world of fascinating periodic structures, if you are, well, just interested.” This program is a bit mathematical, but can be fun for layperson. The program is capable of generating all possible periodic tiling of the plane. Is a plane tiling shareware written by two mathematicians Daniel H Huson and ?. Requires Mathematica to run.įor more programs that does symmetry or tiling related topic, see Wallpaper groups: References and Related Web Sites

Bob (Penrose tiling)īob is a Windows program that does Penrose tilings, by Stephen Collins at It is written by Melinda Green and Don Hatch. Tyler is a Java applet that draw tilings. This is a Java program that lets user interactively draw symmetrical patterns. Tess is a symmetry-drawing program made by Pedagoguery Software Inc. “This applet calculates stellations of majority of uniform polyhedra and their duals.” Polyhedra Stellations Applet, by Vladimir Bulatov. (the latter is good for making paper models of the solid.) Poly is a shareware. A special feature of the program is showing the solids as nets (graphs) and flat un-wrapped represenations. This program contains a fairly complete set of regular and semi-regular solids that includes: Platonic, Archemedean, Prism and Antiprisim, Johnson, Catalan, Dypyramids and Deltohedrons. Poly is another interactive 3D program that does polyhedra. It is very well-done, and with very detailed explanations. One is called HyperSpace Polytope Slicer, which lets you view any of the 6 4D regular polytopes by slice. Mark Newbold has written some beautiful polytope visualization Java appletes. User can rotate the polyhedron, and see its image on the plane change accordingly. This sphere, is then stereo-graphically projected onto a plane. User can choose any of cube, tetrahedron, octahedron, dodecahedron, icosahedron, and they are centrally projected onto a sphere. This applet does Stereographic Projection of regular polyhedrons. Stereop by mathematician John M Sullivan. Partial screenshot of “stereop”, by John M Sullivan There is also SpaceCurve program by the author.
User can also turn on the drawing of tangent plane, tangent line, geodesic, and principal curvature lines at that point. One interesting feature is that users can drag a point inside a box, and the corresponding point on the surface moves dynamically. Spivak is a surface plotter by Jacob Siehler.

Some in Java, some in Flash, some in Mac OS of 1990s, some Microsoft Windows, etc.
