Yehe Liu has added Spatial Hub to ColmapView, a public catalog of COLMAP compatible scene datasets that open directly in the browser viewer.
When ColmapView v0.15 added one click publishing to Hugging Face at the end of September, each upload returned a single viewer link. Spatial Hub serves preview cards for links like those and lists a curated set of public datasets alongside uploads their owners choose to share, and it took its current name and OpsiClear branding on October 30.
Spatial Hub currently lists 4,559 scene entries drawn from 144 sources. Each tile shows the data a scene carries, among them images, cameras, point clouds, masks, meshes and gaussian splats, next to a license tag such as Commercial use with apache-2.0, Non-commercial (NC), or License unspecified. The Gaussians tag requires verified format evidence and a viewer binding, and unverified listings are labeled as Gaussian candidates. Clicking a tile image opens the scene in ColmapView.
Spatial Hub indexes the datasets without hosting them. Some sources require login or publisher approval. Gated Hugging Face tiles open the viewer's browser sign in flow, and publisher approval still applies.
ColmapView v0.20.1 added Share on Hub, which submits a public dataset from a loaded URL or a completed upload. Submissions pass a bot check and server verification, and sources that need operator review stay unpublished until approved. Provider credentials stay in the viewer tab. Every curated scene gets a short link in the form /s/AdjectiveNoun, served by a Cloudflare Worker backend.
ColmapView v0.21.1, the latest published GitHub release, loads matching camera frames on demand from per camera MP4 or WebM video through version 4 manifests, with a 64 MiB frame cache and a self hosted FFmpeg.wasm fallback for codecs the browser cannot decode. The live viewer now also loads explicit Gaussian companions together with camera metadata.
The Hub source is licensed under AGPL-3.0, matching ColmapView, while previews and upstream datasets keep their own licenses. A mirror runs on GitHub Pages.
Spatial Hub is available now in the browser.
