- A Gaussian splat is millions of soft, colored blobs that look like a photo with depth: great to move through, but with no polygons, UVs or collision.
- Marble builds a world from a prompt or an image: draft on 1.0, then rerun on 1.1 or 1.1 Plus. HY World turns a panorama or a walkthrough video into a splat.
- For one object, use TripoSplat or Idol. Export a world as SPZ (or PLY), and view it on the web, in VR, or in Unity and Unreal with a splat plugin.
