Use nerfs

Metaphysic.ai uses neural rendering for high-quality virtual environments and realistic 3D reconstructions, which aligns with the use of Neural Radiance Fields (NeRFs) technology for 3D scene reconstruction or rendering.

Lifecast utilizes Neural Radiance Fields (NeRFs) technology through their software Volurama, which is used for creating volumetric panoramas from short videos on phones. Additionally, the company is involved in the development and application of 3D scene reconstruction and rendering, as evidenced by their focus on photorealistic video backgrounds, volumetric video editing, and rendering pipelines.
