Lifecast is dedicated to pushing the limits of immersive volumetric media. We created a new format for volumetric photos and videos called 'ldi3' which enables real-time 6DOF photorealistic rendering on a wide variety of platforms.
Visit https://lifecast.ai for some demos of what can be done with ldi3 and NeRF, which work on Vision Pro and Quest!
There are a lot of ways to create and edit ldi3. In the /nerf directory, we provide an open source nerf video engine that compresses into ldi3 for web streaming of volumetric/holographic video. We also offer some commercial software for working with ldi3:
- Volurama - a Windows/Mac GUI for the NeRF engine here, for reconstructing static scenes from iPhone video input.
- Volumetric Video Editor - Windows/Mac tool for converting VR180 to ldi3 (not NeRF-based, uses fisheye stereo depth estimation).
- holovolo.tv - text-to-ldi3 with Stable Diffusion
Here is a minimal example of embedding Lifecast ldi3 player in a div. For more examples, check out the /web directory.
