\class Qt3D::QAbstractMeshFunctor
\brief Encapsulates all the required data to build a mesh at any given time.
Each Qt3D::QAbstractMesh implementation needs to provide a Qt3D::QAbstractMeshFunctor.
The functor allows the creation of meshes at runtime by the renderer.
At runtime, mesh functors are compared so that several optimizations can take
place. When implementing the comparison operator you should use
Qt3D::QAbstractFunctor::functor_cast to check that other
Qt3D::QAbstractFunctor instances are of the same type as an alternative
to dynamic_cast.
\note Be sure to add the QT3D_FUNCTOR macro in the public declarations
of your Qt3D::QAbstractMeshFunctor subclass so that
Qt3D::QAbstractMeshFunctor::isType can function properly.
