Gaussian Splatting is a rendering technique that represents a 3D scene as a collection of particles, where each particle is essentially a 3D Gaussian function with various attributes such as position, rotation, non-uniform scale, opacity, and color (represented by spherical harmonics coefficients). Each 3D Gaussian is characterized by a covariance matrix Σ and a center point X, which is referred to as the mean value of the Gaussian: G(X) = e−12 X T Σ−1X. Instead of representing a 3D scene as polygonal meshes, or voxels, or distance fields, it represents it as (millions of) particles: Each particle (“a 3D Gaussian”) has position, rotation and a non-uniform scale in 3D space. In this case, we take text-to-3D and text-to-motion diffusion models as examples.
