Professional tools for volumetric media

An ecosystem of tools for working with Lifecast's ldi3 volumetric media format

Volurama
Volurama is an easy-to-use GUI for Windows and Mac that runs the same powerful NeRF and computer vision algorithms described here.
Volumetric Video Editor
A tool for Windows and Mac that transforms VR180 video (stereoscopic) to ldi3 (volumetric). Uses machine learning based fisheye stereo depth estimation (not NeRF).
render.lifecastvr.com
Convert VR180 to ldi3 in the cloud.
holovolo.tv
Generative AI for volumetric media (text-to-ldi3 using Stable Diffusion).
