SpAItial is pioneering spatial foundation models (SFMs), a groundbreaking AI paradigm that generates virtual environments that behave like the real world.

- Replying to @SpAItial_AIThe best part: it's all open source (GPLv2). Repo + local setup docs here 👇 github.com/spaitial-ai/sp… Build a map from your own .spz and run the whole stack locally. Point Cursor/Claude at the README and it'll walk you through setup.
- Replying to @SpAItial_AIThis was made possible by amazing open source projects: -> @playcanvas — splat rendering + splat-transform -> @agonesdev + @kubernetesio — game-server orchestration -> Pion — WebRTC -> ioquake3 + OpenArena — engine + game data -> @NianticSpatial — SPZ -> q3js — the WASM lineage
- Replying to @SpAItial_AIMultiplayer is WebRTC. Signaling rides through the edge to an in-cluster proxy. Once ICE settles, media is a direct UDP DataChannel browser to game-server pod. One game = one Agones GameServer pod (q3ded) on Kubernetes, with warm pools per region across EU + US.
- Replying to @SpAItial_AIThe rendering trick: two stacked canvases. Back canvas = @playcanvas renders the photoreal splats (.sog, GPU sort, LOD). Front canvas is ioquake3 compiled to WASM draws players, weapons, HUD. The BSP is invisible, as it only does collision + depth so you don't shoot through
- Replying to @SpAItial_AIThe map builder pipeline turns the .spz into a playable level: → splat blob (what you see) → SuGaR Poisson mesh (what you collide with) → .map → BSP via q3map2 (structure + entities) → AAS bot-nav so bots can path → packed into a Q3 .pk3
- Replying to @SpAItial_AIit starts on SpAItial (app.spaitial.ai). Generate a 3D world from a photo/prompt → it comes out as a Gaussian Splat (.spz). The .spz is the only input the game pipeline needs. The scene you generate is the map you play in.
- Photoreal walls. Real geometry. Bots. WebRTC and all open source. Here's how built a fully multiplayer, browser-playable Quake III arena where every level is a 3D world created from a single Image using Echo-2 🧵👇

Having a few hours this afternoon after @CVPR? Consider visiting Red Rocks 20 minutes outside of Denver! For some inspiration, here's a world processed by @SpAItial_AI Echo-2 HQ model from a single phone image! Link to the world in🧵

❄️ New @playcanvas engine example: real-time Depth of Field on Gaussian Splats, powered by the engine's post-processing stack — with scene depth driven by a proxy mesh. Thanks to @SpAItial_AI for the Gaussian Splat + mesh generation 🙏 Live link 👇

Fun weekend project: using @AIatMeta Sam3 to segment objects inside a @SpAItial_AI scene. Pipeline: -> Generate a world on @SpAItial_AI app and export as .ply -> @playcanvas viewer to render splat + a uniform spatial grid over splat centers -> Capture frames + camera pose,
