Oren–Nayar reflectance model

mia_material

Diffuse:
http://en.wikipedia.org/wiki/Oren%E2%80%93Nayar_reflectance_model

Reflection:
Auto link reflections and "highlights" together!
In real world, the Glossy Highlight (we normally talk about "Specalur") is the reflection of light source

Anisotropy:
BRDF: design your own BRDF curve

Engery Conservation rules:
>Transparency "wins" over Diff
>Reflection "wins" over Diffuse+Transparency
>Translucency(半透明) is percentage of Transparency

Practical meaning of above:
>Reflection act as "coating" above transparency+diffuse
>Translucency acts as a "type" of transparency
