ggx()

vec3 GPUShaders::Frag::Brdf_sampler::ggx ( float  NdotV, float  roughness  )

inline

Evaluated the GGX BRDF for a given surface normal, view direction and roughness.

Parameters

NdotV	dot product of the view direction with the surface normal
roughness	the roughness of the surface

Returns

the corresponding value of the BRDF

main()

void GPUShaders::Frag::Brdf_sampler::main ( )

inline

Compute a linear approximation of the GGX BRDF in two coefficients.
