lumos.brdf.library.BINOMIAL

lumos.brdf.library.BINOMIAL(B, C, d, l1)[source]

Binomial scattering model proposed by Greynolds.

Described here: Physically Realistic BRDF Models

Parameters:

B (np.ndarray) – b_i model coefficients
C (np.ndarray) – c_i model coefficients
d (float) – specularity constant
l1 (int) – Minimum Gaussian index

Returns:

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

Return type:

function
