Notas Lanzamiento de GeoGebra 5.0

Esta página ofrece un pantallazo sobre las novedades de GeoGebra 5.0 respecto de la versión 4.0. Para una descripción más detallada, se abre la cordial invitación a consultar el Manual:Página Principal en Español, completamente revisado y actualizado para cada comando de la 4.0 o al Foro Hispanoparlante en que lo espera su moderadora, Liliana Saidon, del Instituto GeoGebra para la República Argentina, Centro Babbage.

Se puede instalar una versión estable de GeoGebra 4.0 usando nuestro instalador en línea Webstart o el de la opción fuera de línea Download.

Información sobre el modo de ejecutar la Versión Beta 5.0 Beta (con 3D) se encuentra en our user forum.

GeoGebra 5.0 requiere para ejecutarse de Java 1.4.2, por lo que se precisa instalar al menos Java 5 desde java.com

Vista 3D

Applets

• 3D export to applets is not supported at the moment

Moving objects

• left-drag points in the 3D view. Click on the point to change the mode "along xOy plane" to "along z axis", and so on.

Translation of the scene

• shift+left-drag the 3D view (without pointing on a moveable object)
• use move view tool

Rotation of the scene

• "Rotate 3D graphic view" tool
• right-drag the 3D view (without pointing on a moveable object)
• continue rotation when mouse released
• view in front of an object (toolbar)

Zoom

• use wheel mouse
• use zoom tool

Gridlines

• show/hide axes, grid, xOy plane
