Context

Radiance field representations have garnered significant interest in recent years due to their ability to enable high-quality, free-viewpoint rendering of 3D and 4D environments derived from 2D images. This capability makes them ideal for immersive applications such as gaming, telepresence, mapping, and the integration of real and virtual scenes and objects. These representations can be realized through implicit methods like Neural Radiance Fields or explicit techniques such as 3D Gaussian Splatting. While these approaches have rapidly advanced, enhancing visual quality, they have also introduced challenges related to interoperability and data compression. This creates a valuable opportunity for standardization committees to define high-performance, standardized solutions.

Both JPEG and MPEG standardization committees recognise the significance of this technology and the need for standards for the coding of radiance fields to enable interoperability between applications and services that make use of radiance field representations.

As part of this activity, on Friday January 31st 2025, the JPEG and MPEG committees jointly organising an online workshop on Radiance Field representations. This workshop consists of a series of presentations that address a topic in the field of Radiance Field representations.
