Web13.6.3 Cosine-Weighted Hemisphere Sampling. As we will see in Section 13.10, it is often useful to sample from a distribution that has a shape similar to that of the integrand being estimated.For example, because the scattering equation weights the product of the BSDF and the incident radiance with a cosine term, it is useful to have a method that generates … WebWe usually estimate the mean of random vectors by computing their sample mean, which equals the vector of sample means of the entries. De nition 1.4 (Sample mean of multivariate data). Let X := fx 1;x 2;:::;x ngdenote a set of d-dimensional vectors of real-valued data. The sample mean is the entry-wise average X:= P n i=1 x i n: (9)
