bsdf ashikhmin(float exponentx, float exponenty, vector framex, vector framey, ...)
bsdf ashikhmin(vector nml, float exponentx, float exponenty, vector framex, vector framey, ...)
An anisotropic bsdf
similar to phong()
but with independent controls for the highlight size along 2 tangent vectors.
exponentx
Phong exponent along the framex
vector.
exponenty
Phong exponent along the framey
vector.
framex
Highlight X direction.
framey
Highlight Y direction.
