| \class Qt3DExtras::QDiffuseSpecularMapMaterial |
| \brief The QDiffuseSpecularMapMaterial provides a default implementation of the phong lighting |
| effect where the diffuse and specular light components are read from texture maps. |
| \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 rough 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. |
