bsdf blinn(float exponent, ...)
bsdf blinn(vector nml, float exponent, ...)
Returns a Blinn BSDF.
See writing a PBR shader for information on BSDFs.
vector blinn(vector nml, vector V, float roughness, ...)
Computes Blinn shading.
nml
The normal of the surface to use for evaluate.
V
The incidence vector.
exponent
The exponent value. The higher the value, the tighter the specular lobe.
Each of the functions can also take an optional light mask.
