Infinite Realities

Infinite Realities is a capture studio in Ipswich, England, that builds its own photometric and motion scanning systems and specializes in digital humans. Lee and Henry run it as a two person team, and the studio's site lists its S0L Motion Scanning, S0L Photometrics and DƐUS Motion Scanning systems. Infinite Realities records performances on its own stage and, for its 4D work, delivers them as sequences of trained Gaussian splats rather than as meshes.

The studio worked with neural radiance fields before it moved to Gaussian splats. In 2023 it showed dynamic NeRFs of people playing back at 30 fps from a custom iteration of Instant NGP, and it captured the Actors dataset that accompanies the HumanRF paper from Synthesia. By October 2023 it was merging splats of ten people into a single scene at a combined 350 MB, rendering at 180 fps on one RTX 4090 in a custom build of Inria's SIBR viewer.

Its reconstruction pipeline treats a performance as a flipbook of per frame Gaussian splats, each frame trained independently. A 2024 session on the stage ran 176 cameras and 484 lights firing in sync, with each second of capture amounting to 127 GB, and a 30 second clip from that session came to more than 300,000 still images. Infinite Realities released 1,800 trained PLY files and the 300,000 source images from that capture publicly, together with a free VR demo built in Unity.

Infinite Realities captured the holographic messages from Superman's Kryptonian parents for Framestore in Ipswich in August 2024. In Framestore CG supervisor Kevin Sears's breakdown of the production, the rig ran 192 cameras recording 12 megapixel images at 24 fps, and each frame resolved to about 1.6 million splats. Infinite Realities trained the sequence in Postshot on 20 processing nodes with RTX 4090 GPUs, cropped the actors in 3D, removed the ground plane and delivered a PLY sequence, and the shots were rendered through a SIBR Viewer build carrying opacity and alpha controls the studio added.

Infinite Realities works on commission and publishes no prices. Its deliverables are standard PLY splat sequences that open in any 3DGS viewer or digital content creation tool that reads the format, and Framestore's FX team worked the Superman sequence in Houdini with GSOPs before compositing it in Nuke.
