It’s literally the name of gaussian splatting. 3D Gaussian Splatting for Real Time Radiance Fields

Hmm if gaussian splatting is radiance field rendering then so is any 3D rendering, and what's the point of using the name? Though having looked up the name it seems like it isn't well defined enough to mean much anyway tbh.
