How to Use GeoGebra's 3D Graphics Tools

What are Tools?
[size=100]GeoGebra's [i]3D Graphics View [/i]provides a [i]Toolbar [/i]with a selection of [i]Tools[/i]. You may [b]activate a [/b][i][b]Tool[/b] [/i]by clicking on the button showing the corresponding icon.[br][br][b]Task[/b]: Create a sphere using the [icon]/images/ggb/toolbar/mode_sphere2.png[/icon] [i]Sphere with Center through Point[/i] tool.[br][/size][list=1][*][size=100]Select the tool [img][/img] [i][i]Sphere with Center through Point[/i][/i] from the [i]3D Graphics View Toolbar[/i].[/size][/*][*][size=100]Click twice in the [i]3D Graphics View[/i] in order to create a sphere.[/size][/*][*][size=100]Select the [img][/img] [i]Move [/i]tool and drag the points in order to change the sphere's size and / or position.[/size][/*][/list]

How to move objects in the 3D coordinate system
[size=100]In order to move a point in the three-dimensional coordinate system, you can [b]switch between two modes[/b] by repeatedly clicking on the point while the [img][/img] [i]Move[/i] tool is activated:[br][list][*][b]Mode [i]xOy[/i]-plane[/b]: You may move the point parallel to the [i]xOy[/i]-plane without changing the [i]z[/i]-coordinate.[/*][*][b]Mode [i]z[/i]-axis[/b]: You may move the point parallel to the [i]z[/i]-axis without changing the [i]x[/i]- and [i]y[/i]-coordinates. [/*][/list][/size]
What are Toolboxes?
[size=100]GeoGebra's [i]Tools[/i] are organized in [i]Toolboxes[/i], containing similar [i]Tools [/i]or [i]Tools [/i]that generate the same type of new object. You can [b]open a [/b][i][b]Toolbox[/b] [/i]by clicking on a [i]Tool [/i]button and selecting a [i]Tool [/i]from the appearing list.[br][br][b]Task[/b]: Create a cube using the [icon]/images/ggb/toolbar/mode_cube.png[/icon] [i]Cube[/i] tool.[br][/size][list=1][*][size=100]Search the [i]Toolboxes [/i]for the [img][/img] [i]Cube[/i][i] [/i]tool.[br][/size][/*][*][size=100]Click twice in the [i]3D Graphics View[/i] in order to create a cube.[/size][br][/*][*][size=100]Select the [img][/img] [i]Move [/i]tool and drag the points in order to change the cube's size and / or position.[br][/size][/*][/list]
What are Tooltips?
[size=100]If you select a [i]Tool[/i], [b]a [i]Tooltip [/i]appears[/b] explaining how to use this [i]Tool[/i].[br][u]Hint[/u]: When you click on a [i]Tooltip[/i], a web page providing help for the selected [i]Tool [/i]opens in your browser window.[br][br][b]Task[/b]: Create a pyramid using the [icon]/images/ggb/toolbar/mode_pyramid.png[/icon] [i]Pyramid [/i]tool works[br][/size][list=1][*][size=100]Select the [img][/img] [i][size=100][i]Pyramid [/i][/size] [/i]tool.[/size][/*][*][size=100]Read the [i]Tooltip.[/i][/size][/*][*][size=100]Figure out how to use this tool in order to create a pyramid.[/size][br][/*][/list]

The 3D Graphics Tools

The 3D Graphics View Toolbar
[size=100]The [i]3D Graphics View Toolbar[/i] provides a wide range of [i]Tools[/i] that can be operated with the pointer. They allow you to create the three-dimensional graphical representations of objects directly in the [i]3D Graphics View[/i]. [br][br][img][/img][br][br]Every icon in the [i]Toolbar[/i] represents a [i]Toolbox[/i] that contains a selection of related construction tools. In order to open a [i]Toolbox[/i], you need to click on the corresponding default [i]Tool[/i] shown in the [i]3D Graphics View Toolbar[/i].[br][/size]
