bsdf cone(vector normal, vector dir, float angle, ...)
Returns a bsdf
representing a cone reflection along a given direction vector. This BSDF is constant within the given ‹angle›, producing a similar result to the gather or irradiance loops.
bsdf cone(vector dir, float angle, ...)
In shading contexts, fills in the current surface normal automatically.
normal
The surface normal direction.
dir
The direction of specularity.
angle
Cone angle in radians.
