We present a novel <i>anisotropic Spherical Gaussian</i> (ASG) function, built upon the <i>Bingham distribution</i> [Bingham 1974], which is much more effective and efficient in representing anisotropic spherical functions than Spherical Gaussians (SGs). In addition to retaining many desired properties of SGs, ASGs are also rotationally invariant and(More)
