Web22 mei 2024 · The original charge q plus the image charge q ′ = − qR / D puts the sphere at zero potential. The additional image charge at the center of the sphere raises the potential of the sphere to. V = Q0 + qR / D 4πε0R. The force on the sphere is now due to the field from the point charge q acting on the two image charges: 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 …
