++ \class Qt3DExtras::QDiffuseMapMaterial
++ \brief The QDiffuseMapMaterial provides a default implementation of the phong lighting effect
++ where the diffuse light component is read from a texture map.
++ \inmodule Qt3DExtras
++ \since 5.7
++ \inherits Qt3DRender::QMaterial
++
++ \deprecated
++ This class is deprecated; use Qt3DExtras::QDiffuseSpecularMaterial instead.
++
++ The specular lighting effect is based on the combination of 3 lighting components ambient,
++ diffuse and specular. The relative strengths of these components are controlled by means of
++ their reflectivity coefficients which are modelled as RGB triplets:
++
++ \list
++ \li Ambient is the color that is emitted by an object without any other light source.
++ \li Diffuse is the color that is emitted for rought surface reflections with the lights.
++ \li Specular is the color emitted for shiny surface reflections with the lights.
++ \li The shininess of a surface is controlled by a float property.
++ \endlist
++
++ This material uses an effect with a single render pass approach and performs per fragment
++ lighting. Techniques are provided for OpenGL 2, OpenGL 3 or above as well as OpenGL ES 2.
