MetaLoom // Lumen is the spatial media engine. You hand it video of a place; it reconstructs the place as a three-dimensional Gaussian-splat scene, keeps every scene in a versioned store, and lets you find places again — with a sentence, with a photograph, or with a new capture of the same location.
Lumen is a commercial offering. Unlike the open source MetaLoom platform, it is licensed per deployment and ships as a container image for your own GPU hardware — see the product page for what it does and whom to talk to.
What Lumen is for
Video is the easiest way to capture a place and the hardest way to find one again. A folder of clips has no notion of where — two recordings of the same café share nothing a filename search could discover. Lumen’s answer is to make the place itself the unit of storage: captures are reconstructed into scenes, scenes are indexed, and every question — "where was that?", "have I been here before?", "does this footage show the same room?" — is answered against reconstructed geometry, not against file metadata.
Three properties distinguish it:
-
Real reconstruction. Scenes are trained radiance fields rendered as Gaussian splats, not photo carousels. A scene can be orbited interactively in the browser, rendered from any viewpoint, and described in words.
-
A store, not files. Scenes live in a write-ahead log with quantised primitives, spatial ordering, compaction, level-of-detail pyramids and published quality tiers. Any scene can be read at any point in its history.
-
Honest retrieval. Search is calibrated against measured score distributions: a place that is not in the corpus is refused, not approximated. Merging two captures of one venue requires geometric verification, never mere similarity.
