Hello everybody,
I have measured a surface of metal with a topographical instrument. Hence my
surface is composed of many micro facet.
My goal is to study the surfacic diffusion of light onto this surface (like
the gloss...). I need to make physically realistic simulation.
My problem is to set the finish of my object to fullfill my objectif.

Do you have any idea of howw I should proceed?
I join what i tried:
/////
 finish{

        diffuse 0
        ambient 0
        conserve_energy
  reflection {
    0.0, 1.0
    fresnel on

}
specular 1

}

       interior{ior 1.5}
/////

Thanks by advance
pierre
