Object attributes

C.a.R.

C.a.R. is a free GPL analog of The Geometer's Sketchpad (GSP), written in Java.

Cabri

Cabri Cabri was developed by the French school of mathematics education in Grenoble (Laborde, 1993)

CaRMetal

CaRMetal is a free GPL software written in Java. Derived from C.a.R., it provides a different user interface.

Cinderella

Cinderella, written in Java, is very different from The Geometer's Sketchpad. The later version Cinderella.2 also includes a physics simulation engine and a scripting language. Also, it now supports macros, line segments, calculations, arbitrary functions, plots, etc. Full documentation is available online.

Dr Genius

Dr Genius was an attempt to merge Dr. Geo and the Genius calculator.

Dr. Geo

Dr. Geo is a GPL interactive software intended for younger students (7-15). The later version, Dr. Geo II,^[4] is a complete rewrite of Dr. Geo, for the Squeak/Smalltalk environment.

GCLC

GCLC^[5] is a dynamic geometry tool for visualizing and teaching geometry, and for producing mathematical illustrations. In GCLC, figures are described rather than drawn. This approach stresses the fact that geometrical constructions are abstract, formal procedures and not figures. A concrete figure can be generated on the basis of the abstract description. There are several output formats, including LaTeX, LaTeX/PStricks, LaTeX/Tikz, SVG and PostScript. There is a built-in geometry theorem prover (based on the area method). GCLC is available for Windows and Linux. WinGCLC is a Windows version of GCLC with a graphical interface that provides a range of additional functionalities. GCLC is open source software (licence CC BY-ND).

GeoGebra

GeoGebra is software that combines geometry, algebra and calculus for mathematics education in schools and universities. It is available free of charge for non-commercial users.^[6]

• License: open source under GPL license (free of charge)
• Languages: 55
• Geometry: points, lines, all conic sections, vectors, parametric curves, locus lines
• Algebra: direct input of inequalities, implicit polynomials, linear and quadratic equations; calculations with numbers, points and vectors
• Calculus: direct input of functions (including piecewise-defined); intersections and roots of functions; symbolic derivatives and integrals (built-in CAS); sliders as parameters
• Parametric Graphs: Yes
• Implicit Polynomials: Yes
• Web Export: all constructions exportable as web pages as a Java applet
• Macros: usable both as tools with the mouse and as commands in the input field
• Animation: Yes
• Spreadsheet: Yes, the cells can contain any GeoGebra object (numbers, points, functions etc.)
• Dynamic text: Yes (including LaTeX)
• Platforms: Mac OS, Unix/Linux, Windows (any platform that supports Java 1.5 or later)
• Continuity: uses a heuristic 'near-to-approach' to avoid jumping objects

GeoKone.NET

GeoKone.NET^[7] is an interactive recursive natural geometry (or "sacred geometry") generator that runs in a web browser. GeoKone allows the user to create geometric figures using naturalistic rules of recursive copying, such as the Golden ratio.

Geolog

Geolog^[8] is a logic programming language for finitary geometric logic.

Geometry Expressions

Geometry Expressions^[9] Does symbolic geometry. It uses real symbolic inputs and returns real and symbolic outputs. It emphasises use with a Computer Algebra System (CAS), as well as exporting and sharing via interactive HTML5, Lua, and OS X dashboard widget apps.

Jeometry

Jeometry is a dynamic geometry applet.

Kig

Kig is a free (GPL) analog of The Geometer's Sketchpad (GSP) for KDE, but more calculus-oriented. It is a part of the KDE Edutainment Project.

KmPlot

KmPlot is a mathematical function plotter released under the free GPL license. Includes a powerful parser and precision printing in correct scale. Simultaneously plot multiple functions and combine function terms to build new functions. Supports functions with parameters and functions in polar coordinates. Several grid modes are available. Features include:

• powerful mathematical parser
• precise metric printing
• different plot types (functions, parametric, polar)
• highly configurable visual settings (plot line, axes, grid)
• export to bitmap format (BMP and PNG) and to Scalable Vector Graphics (SVG)
• save/load complete session in readable XML format
• trace mode: cross-hair following plot, coordinates shown in the status bar
• zooming support
• ability to draw the 1st and 2nd derivative and the integral of a plot function
• support user-defined constants and parameter values
• various tools for plot functions: find minimum/maximum point, get y-value and draw the area between the function and the y-axis

KSEG

KSEG is a free (GPL) analog of The Geometer's Sketchpad (GSP) with some unique features. This software can handle heavy, complex constructions in Euclidean geometry.

Live Geometry

Live Geometry is a free CodePlex project that lets you create interactive ruler and compass constructions and experiment with them. It is written in Silverlight 4 and C# 4.0 (Visual Studio 2010). The core engine is a flexible and extensible framework that allows easy addition of new figure types and features. The project has two front-ends: WPF and Silverlight, which both share the common DynamicGeometry library.
