++ \brief Demonstrates using physical materials.

++
++ 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
