Encoding and decoding a representation of a 3D scene

Abstract

The invention provides a bitstream, an encoding apparatus and method for encoding the bitstream, and a decoding apparatus and method for decoding the bitstream. The bitstream comprises a first plurality of encoded data structures and at least one further plurality of encoded data structures. Each data entry in each encoded data structure of the first plurality comprises parameters for a respective 3D Gaussian splat in a first set of 3D Gaussian splats representing a 3D scene at a first moment in time. Each data entry in each encoded data structure of each further plurality comprises parameters for a respective 3D Gaussian splat in a further set of 3D Gaussian splats representing the 3D scene at a further moment in time. Each data structure in each further plurality corresponds to a data structure in the first plurality. Corresponding data structures have the same number of data entries as one another.
