Spherical harmonics lecture note
WebIn 3D computer graphics, spherical harmonics play a special role in a wide variety of topics including indirect lighting (ambient occlusion, global illumination, precomputed radiance transfer, etc.) and modeling of 3D shapes. ... Note the role that the angular momentum part plays. It appears as a repulsive force that tends to push the particle ... Web- When solving problems with both charges and boundary surfaces, the mathematics is simplified if the Green's function is expanded in spherical harmonics. - The addition theorem was used to find the spherical harmonics expansion of a unit charge potential and is as follows: Expansion A: 1 ∣r−r0∣ =4 ∑ l=0 ∞∑ m=−l l1 2l 1 rl r0 l 1 Yl m * ', ' Y

(-1) m in the definition of this function: note however that our definition of the associated Legendre polynomial already includes this term. This implementation returns zero for m > n For θ outside [0, π] and φ outside [0, 2π] this implementation follows the convention used by Mathematica: the ...
WebSpherical harmonics are employed in a wide range of applications in computational science and physics, and many of them require the rotation of functions. We present an efficient and accurate algorithm for the rotation of finite spherical harmonics ...
