DolphinSurfaceGgx

Same GGX/Smith/Schlick direct-light lobe used by Dolphin Lightlab. The result already includes N dot L; callers supply incoming radiance separately.

Compose linear-color surfaces and shared shading math in ordinary Yeho code.

external DolphinSurfaceGgx(float roughness,float f0,float nx,float ny,float nz,float vx,float vy,float vz,float lx,float ly,float lz) returns float

Status: source-declared

Parameters

float roughness

Supply roughness as float.

float f0

Supply f0 as float.

float nx

Supply nx as float.

float ny

Supply ny as float.

float nz

Supply nz as float.

float vx

Supply vx as float.

float vy

Supply vy as float.

float vz

Supply vz as float.

float lx

Supply lx as float.

float ly

Supply ly as float.

float lz

Supply lz as float.
