    \title Qt Quick 3D Physics - Cannon Example
    \examplecategory {3D}
    \brief Demonstrates how to spawn physical objects.
    \image cannon-example.jpg

    This example demonstrates how to create and delete physical objects on demand.
    The scene consists of a number of stacks of boxes.
    You can move around by using \c WASD and the mouse and shoot a ball by pressing \c space.

    The scene is setup with the usual Qt Quick 3D objects like view, camera and light:

    \snippet cannon/main.qml camera

    \snippet cannon/main.qml light

    We also add a static floor:

    \snippet cannon/main.qml floor

    We create a Node we use as the spawner of objects and put inside our view:

    \snippet cannon/main.qml spawner

    We have three methods: \c createStack for creating a stack, \c createBall for creating a ball with velocity and \c reset for resetting the scene.
    The actual box and sphere that is spawn is stored in their own qml files (\c box.qml and \c sphere.qml).
