\brief Edit a 3D scene.
When editing a 3D scene, you view the scene in the \uicontrol{3D}
view. You can change the projection of the view by switching between
\e {perspective camera} and \e {orthographic camera} modes. When using the
perspective camera mode, components that are far from the camera appear
smaller than those nearby. In the orthographic camera mode, all components
appear at the same scale irrespective of their distance from the camera.
Both of them are free-form camera modes that you can use to orbit around
the scene.
view.
When you import 3D scenes from files that you exported from 3D graphics
tools, you also import a \l{Cameras}{scene camera},
\l{Lights}{light}, \l{3D Models}{model}, and
\l {Materials and Shaders}{materials}. If your scene did not contain
them, you can add the corresponding \l {3D Components}{Qt Quick 3D}
\l{Lights}{light}, \l{3D Models}{model}, and \l {Materials and Shaders}{materials}.
If your scene does not contain them, add the corresponding \l {3D Components}{Qt Quick 3D}
components from \uicontrol Components > \inlineimage icons/plus.png
> \uicontrol {Qt Quick 3D} > \uicontrol {Qt Quick 3D}.
You can use the toolbar buttons
to \e transform 3D components and manipulate the 3D scene. Transformation
refers to moving, rotating, or scaling of a component. The \e pivot of the
component is used as the origin for transformations. You can set a
\l{Managing 3D Transformations}{local pivot offset} for a component in
\uicontrol Properties to transform the component around a point other than
its local origin. A line is drawn in the \uicontrol{3D} view from the pivot
point to the center of the component to provide a visual connection between
them. Especially when working with complex scenes, it may be useful to use
the \l {Showing and Hiding Components}{showing and hiding} or the
\l {Locking Components}{locking} features in \l Navigator to avoid
transforming components by mistake while editing your scene.
Use the \uicontrol 3D toolbar buttons to modify the \uicontrol 3D view,

connection between them.
Toggle between local and global orientation to determine whether the gizmos
affect only the local transformations of the component or whether they
transform with respect to the global space.
Another helpful feature when editing 3D scenes is the \e {edit light},
which is a quick way to light the scene.
Additionally, you can toggle the visibility of the grid, selection boxes,
icon gizmos, and camera frustums in the 3D scene.
There is a context menu in the \uicontrol 3D view. To open it, right-click
in the \uicontrol 3D view. From the context menu you can:

\li Open \uicontrol {Material Editor} and edit materials.
