caption_attribution_description: Deutsch: Bildschirmfoto der Software CaRMetal. Zu sehen sind die Konstruktion einer Ellipse und einer Hyperbel. English: Construction of an ellipse and hyperbola with CaRMetal.
context_page_description: CaRMetal is an interactive geometry program which inherited the C.a.R. engine. The software has been created by Eric Hakenholz, in Java. CaRMetal is free, under GNU GPL license. It keeps an amount of functionality of C.a.R. but uses a different graphical interface which purportedly eliminates some intermediate dialogs and provides direct access to numerous effects. 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 can be set using a separate panel.
  CaRMetal also supports a configurable restricted construction palette and has assignment capabilities, which use an apparently unique feature called Monkey. CaRMetal has a scripting language which allows the user to build rather complex figures like fractals.

CaRMetal has a scripting language (JavaScript) which allows the user to build rather complex figures like fractals. CaRMetal has several locales including French, English, Spanish, German, Italian, Dutch, Portuguese and Arabic.
