    \brief Demonstrates the use of View3D to show a scene from multiple cameras.

    This example demonstrates using four separate \l {View3D}s with different cameras in an
    application.

    \section1 Defining the Cameras

    First we define the \l {Camera}{cameras}. We're going to define several different cameras, even
    though we will only add 4 views. We're doing this because we want to be able to switch the
    camera in one of the views.

    The cameras have to be defined inside the root \l Node. This is how the cameras are defined:

    \snippet view3d/main.qml rootnode
    \dots
    \snippet view3d/main.qml cameras start
    \dots
    \snippet view3d/main.qml cameras end

    \section1 Adding the Views

    After defining the cameras we can add the \l {View3D}{views}. We divide the screen to four
    parts, and add views one-by-one like this:

    \snippet view3d/main.qml views
    \dots

    The top-right view has three buttons in it. The buttons can be used to switch the camera used
    in that view on the fly. The switching is done just by settings the camera property:

    \snippet view3d/main.qml buttons
    \dots
