If you’re reading this, then you’re probably already familar with how a Gaussian function works in 1D: you compute the distance from the center of the Gaussian, and use this distance as part of a base-e … See more Now that we know what a Spherical Gaussian is, what’s so useful about them anyway? One pontential benefit is that they’re fairly intuitive: it’s not terribly hard to understand how … See more So what are these useful Gaussian properties that we can exploit? For starters, taking the product of 2 Gaussians functions produces another Gaussian. For an SG, this is … See more If we were to use our SG integral formula to compute the integral of the product of two SG’s, we can compute what’s known as the inner product, or dot productof those SG’s. The operation is usually defined like … See more Gaussians have another really nice property in that their integrals have a closed-form solution, which is known as the error function. The property also extends to SG’s, where we can compute the integral of an SG … See more
