Veach (Anisotropic along XY), Fig. 10

We demonstrate the performance of our CPNEE under different anisotropy directions, with the noise first stretched along the slab's normal by a factor of 1000, then compressed along either horizontally (upper slab in each set of slabs) or vertically (lower slab in each set of slabs) by a factor of 10. Since the in general, the relationship between the vNDF and the light would be complex, a more careful design of the choice of u and v would be a potential field of research direction.
