44 \class Qt3DExtras::QPerVertexColorMaterial
45 \ingroup qt3d-extras-materials
46 \brief The QPerVertexColorMaterial class provides a default implementation for rendering the
47 color properties set for each vertex.
48 \inmodule Qt3DExtras
49 \since 5.7
50 \inherits Qt3DRender::QMaterial
51
52 This lighting effect is based on the combination of 2 lighting components ambient and diffuse.
53 Ambient is set by the vertex color.
54 Diffuse takes in account the normal distribution of each vertex.
55
56 \list
57 \li Ambient is the color that is emitted by an object without any other light source.
58 \li Diffuse is the color that is emitted for rough surface reflections with the lights
59 \endlist
60
61 This material uses an effect with a single render pass approach and forms fragment lighting.
62 Techniques are provided for OpenGL 2, OpenGL 3 or above as well as OpenGL ES 2.
