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. |
