819 +        Ashik2 is the anisotropic reflectance model by Ashikhmin & Shirley.
820 +        The string arguments are the same as for <a HREF="#Plastic2">plastic2</a>, but the real
821 +        arguments have additional flexibility to specify the specular color.
822 +        Also, rather than roughness, specular power is used, which has no
823 +        physical meaning other than larger numbers are equivalent to a smoother
824 +        surface.
