Phong material

 The list of Phong parameter :
 
 Ka   Ambient-reflection coefficient. 
Ks Specular-reflection coefficient
Kd Diffuse-reflection coefficient. 
Kh highlight coefficient. ( Early it was included in the Ks parameter)
Kt Refraction coefficient.
ni  index of refraction.
n Specular-reflection exponent.
Od Diffuse color.
Os Specular color.
Shadows Draw shadows if on.
doubleside
angles  angular spread of reflected ray. *
anglets  angular spread of refraction ray. *

With the "Put in library" the material will be save into the library and could be reload after using the Insert|Library|Material.
 

To use angles and anglet, UseDistribuiteTS must be on. With AngleFreq you can choose the quantity of rays fired for each point in the worst case.
