\class Qt3D::QPerVertexColorMaterial
\brief The QPerVertexColorMaterial class provides a default implementation for rendering the color properties set for each vertex.
\inmodule Qt3DRenderer
\since 5.5
This lighting effect is based on the combination of 2 lighting components ambient and diffuse. Ambient is set by the vertex color.
Diffuse takes in account the normal distribution of each vertex.
\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
\endlist
This material uses an effect with a single render pass approach and forms fragment lighting.
Techniques are provided for OpenGL 2, OpenGL 3 or above as well as OpenGL ES 2.
