Quote - The color of metals

 

 

Eh!

http://en.wikipedia.org/wiki/Extinction_coefficient

Nd= n+ Ki

n=refractive index

k=Extinction coefficient: imaginary part of complex index of refraction

I= Watts/Steradians

Nd=Final refractive index

 

Okay ?

Enjoy

 

Sorry for my bad english, but, the realistic metal is not possible into poser (need spectral simulation )......., (7 hours of simulation for 24 poly and 3 raytrace bounces)

Gold

Silver

 

Nickel
