This type is deprecated. We strongly advise against using it in new code.
The phong 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:
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.
alpha : real |
Holds the alpha component of the object which varies between 0 and 1.
The default value is 0.5.
ambient : color |
Holds the current ambient color.
blendFunctionArg : BlendEquation::BlendFunction |
Holds the blend equation function argument.
