CaRMetal is an interactive geometry program which inherited the C.a.R. engine.
The software retains some of C.a.R’s functionality, but employs a different graphical interface which is designed to remove some intermediate dialogs.
Constructions are done using a main palette, which contains some useful construction shortcuts in addition to the standard compass and ruler tools. These include perpendicular bisector, circle through three points, circumcircular arc through three points, and conic section through five points. Also interesting are the loci, functions, parametric curves, and implicit plots. Element thickness, color, label, and other attributes (including the so-called magnetic property) can be set using a separate panel.
Features include:
- Workbooks – folder system allowing one to put several figures in one folder, called “workbook”. It is easy to navigate between the sheets of a workbook, to duplicate a sheet (or figure), to merge several workbooks into one.
- Numeric display.
- Real 3D mode which comes up with a regular tetrahedron, a cube, a diamond and a regular dodecahedron. It is also possible to bind a point to the inside of a (3D) circle or polygon.
- Magnetism.
- Run CaRMetal as a server.
- JavaScript
