The User Interface
The User Interface of the GeoGebra 3D Grapher consists of the 
Algebra View and the 
3D Graphics View of GeoGebra. Both Views are dynamically connected, which means that modifications in any View are immediately displayed in the other View as well.
Examples:
Algebra View and the 3D Graphics View of GeoGebra. Both Views are dynamically connected, which means that modifications in any View are immediately displayed in the other View as well.
Examples:
- Enter the equation of a plane (e.g.
x+y+z=1) or a function (e.g.f(x,y)=sin(x)*sin(y))in the Algebra View and watch how it is graphed in the 3D Graphics View.
- Drag a point in the 3D Graphics View and watch how its coordinates change in the Algebra View.
