Gaussian splatting

Gaussian splatting is a volume rendering technique that deals with the direct rendering of volume data without converting the data into surface or line primitives. The technique was originally introduced as splatting by Lee Westover in 1991. This technique was revitalized and exploded in popularity in 2023, when Bernhard Kerbl and Georgios Kopanas at Inria proposed the seminal 3D Gaussian splatting that offers real-time radiance field rendering. Like other radiance field methods, it can convert multiple images into a representation of 3D space, then use the representation to create images as seen from new angles. Multiple works soon followed, such as 3D temporal Gaussian splatting that offers real-time dynamic scene rendering.
