++ \title Qt Quick 3D Physics - Cannon Example
++ \examplecategory {3D}
++ \brief Demonstrates how to spawn physical objects.
++ \image cannon-example.jpg {Screenshot of a green landscape with multiple red boxes forming

++
++ 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).
