    \title Qt Quick 3D Physics - Material Example
    \brief Demonstrates using physical materials.
    \image material-example.jpg

    The \e {Material} example demonstrates how to control the material properties of a physical body.
    The scene contains the usual boilerplate of a View3D, PhysicsWorld, PerspectiveCamera and DirectionalLight.
    In addition to this the scene contains two physical bodies, namely a slightly tilted plane and a box.
    Every physical body has a \l {PhysicsBody::} {physicsMaterial} property containing a PhysicsMaterial node.
    PhysicsMaterial contains these three material properties; \l {PhysicsMaterial::} {staticFriction}, \l {PhysicsMaterial::} {dynamicFriction} and \l {PhysicsMaterial::} {restitution} and these are used to define how the body will act when colliding with and sliding against other bodies.
    There is a simple user interface that allows to interactively tweak the material of the box so you can see how it interacts depending on its material properties.

    This is the QML code for the material:

    \snippet material/main.qml material

    The material is simply referencing the values of the user interface's sliders.
    This same material is then used for both the box and the floor:

    \snippet material/main.qml box

    \snippet material/main.qml floor
