lumos.brdf.library.GAUSSIAN(A, sigma)[source]

Gaussian scattering model.

\(BRDF = A exp(\frac{\hat{w}_r\cdot\hat{w}_o - 1}{\sigma})\)

Parameters:

A (float) – Height of specular peak of BRDF
sigma (float) – Width of specular peak

Returns:

BRDF function, where f = BRDF(incident vector, normal_vector, outgoing_vector)

Return type:

function
