By default, the 3D Graphics View is opened next to the Algebra View. In addition, either the Input Bar is displayed at the bottom of the GeoGebra window (GeoGebra Desktop), or an Input Field is integrated directly in the Algebra View (GeoGebra Web and Tablet Apps). The 3D Graphics View Toolbar is displayed at the top of the GeoGebra window, with the Undo / Redo buttons in the top right corner.

3D Graphics View

The 3D Graphics View is part of the 3D Graphics Perspective, although you may add a 3D Graphics View window to any Perspective at any time by using the View Menu or the Views button in the Style Bar.

You can customize the 3D Graphics View according to the mathematical topic you want to work with. The basic setup can be changed using the 3D Graphics View Style Bar (e.g. display of coordinate axes, xOy-plane, grid). In addition, the Preferences Dialog provides more options to customize the 3D Graphics View. You may also change the layout of GeoGebra’s user interface according to your needs.

Szerkesztés egérrel

Using the construction Tools available in the 3D Graphics View Toolbar you can create geometric constructions in the 3D Graphics View with the mouse. Select any construction tool from the 3D Graphics View Toolbar and read the tooltip provided in the 3D Graphics View in order to find out how to use the selected Tool.

Jegyzet: Any object you create in the 3D Graphics View also has an algebraic representation in the Algebra View.

Select the Sphere with Center through Point Tool and click in the 3D Graphics View twice. The first click creates the center point while the second click creates a sphere and a point on the sphere.

The 3D Graphics View Toolbar provides a wide range of Tools that can be operated with the mouse and allow you to create the three-dimensional graphical representations of objects directly in the 3D Graphics View. Every icon in the Toolbar represents a Toolbox that contains a selection of related construction Tools. In order to open a Toolbox, you need to click on the corresponding default Tool shown in the 3D Graphics View Toolbar (GeoGebra Web and Tablet Apps) or on the small arrow in the lower right corner of the Toolbar icon (GeoGebra Desktop).

Jegyzet: The Tools of the 3D Graphics View Toolbar are organized by the nature of resulting objects or the functionality of the Tools. You will find Tools that create different types of planes in the Planes Toolbox or Tools that allow you to create geometric solids in the Geometric Solids Toolbox.

GeoGebra’s 3D Graphics View supports points, vectors, lines, segments, rays, polygons, and circles in a three-dimensional coordinate system. You may either use the Tools provided in the 3D Graphics View Toolbar, or directly enter the algebraic representation of these objects in the Input Bar or Input Field of the Algebra View (GeoGebra Web and Tablet Apps).

Enter A=(5, -2, 1) into the Input Bar or Input Field of the Algebra View in order to create a point in the three-dimensional coordinate system.

Furthermore, you may now create surfaces, planes, as well as geometric solids (pyramids, prisms, spheres, cylinders, and cones).

Enter f(x, y)=sin(x*y) in order to create the corresponding surface.

Parancsok

In addition to the wide range of /s_index_php?title=Kategória:Commands_action=edit_redlink=1.adoc[Commands] available for the other Views of GeoGebra, there also is a selection of 3D Commands specifically for the 3D Graphics View.

Let A=(2, 2, 0), B=(-2, 2, 0), C=(0, -2, 0), and D=(0, 0, 3). Input the command Pyramid[A, B, C, D] and hit the Enter key in order to create the pyramid with base ABC and apex D.

Mozgatás eszköz

Using the Move Tool you may drag and drop Free Points in the 3D Graphics View. In order to move a point in the three-dimensional coordinate system, you can switch between two modes by clicking on the point:

Mode xOy-plane: You may move the point parallel to the xOy-plane without changing the z-coordinate.
Mode z-axis: You may move the point parallel to the z-axis without changing the x- and y-coordinates.

In the 3D Graphics View, you may use the Page Up key in order to move a selected object up and the Page Down key in order to move a selected object down.

Koordináta-rendszer eltolása

You may translate the coordinate system by using the Move Graphics View Tool and dragging the background of the 3D Graphics View with your pointing device. Thereby, you can switch between two modes by clicking on the background of the 3D Graphics View:

Mode xOy-plane: You may translate the scene parallel to the xOy-plane.
Mode z-axis: You may translate the scene parallel to the z-axis.

Alternatively you can hold the Shift key and drag the background of the 3D Graphics View in order to translate the coordinate system. Again, you need to click in order to switch between the two modes while holding the Shift key.

Jegyzet: You can go back to the default view by selecting the button Back to Default View in the 3D Graphics View Style Bar.

Koordináta-rendszer forgatása

You may rotate the coordinate system by using the Rotate 3D Graphics View Tool and dragging the background of the 3D Graphics View with your pointing device.

Alternatively you can right-drag the background of the 3D Graphics View in order to rotate the coordinate system.

If you want to continue the rotation of the coordinate system when the mouse is released, you may use the option Start Rotating the View and Stop Rotating the View in the 3D Graphics View Style Bar.

Jegyzet: You can go back to the default rotation by selecting the button Rotate back to default view in the 3D Graphics View Style Bar.

Objektummal szemközti nézet

You may use the View in front of Tool in order to view the coordinate system from a viewpoint in front of the selected object.

Nagyítás

You may use the Zoom In Tool and Zoom Out Tool in order to zoom in the 3D Graphics View. /s_index_php?title=Sablon:Hint_action=edit_redlink=1.adoc[Sablon:Hint]
