Geometry and graphics

A graphic output is made of a 2-d or 3-d scene with controls, it corresponds to a unique commandline above it. You can create some examples easily using the Graph menu.

A geometry figure is the display of a 2-d or 3-d graphic scene representing the graphical objects of the commandlines that are on it's left:

• you may create some geometric objects using the mouse (points, lines, triangles, circles, etc.),
• alternatively you can enter commandlines, with the help of the Geo menu
• interactive geometry is implemented by moving points in pointer mode or by moving special objects called parameters or cursors.
