WebThe Lafortune representation is evaluated in local surface coordinates. The x axis and y axis are in the direction of anisotropy (the scratch or thread direction), and the z axis is the normal. Defining the matrix C as C x = -1, C y = -1, C z = 1 causes i to reflect about the normal, yielding a standard Phong lobe. But the C coefficients may take on other values to … WebWe evaluate encoding results on isotropic and anisotropic BRDFs from multiple real-world datasets, and importance sampling performance for isotropic BRDFs mapped to two different analytic models.
