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 the early 1990s. With advancements in computer graphics, newer methods such as 3D and 4D Gaussian splatting have been developed to offer real-time radiance field rendering and dynamic scene rendering respectively.
