With 𝐄𝐜𝐡𝐨-𝟑, you can turn the world around you into a 3D space 🌎 I scanned my apartment in less than 5 minutes, and the level of detail in the reconstruction is amazing! 😀 You can explore your space, ask questions about it, redesign it, and much more. Check below! 🤓👇

Answering some FAQ: Can I try it without buying credits? Yes! You get a free month when you subscribe. Can I export my generations? Yes, sign in to our web platform at app.spaitial.ai with the same account to view and export your generations to SPZ, PLY, SOG and collision meshes. Is there API access to Echo-3 and can I integrate into my own capture app? Yes! We are already working with partners integrating the api. Reach out to [email protected] for more details Android when? We are working to it. Coming soon.

You can generate worlds from your phone scans and use the web app to record and export multiple views. One generation and many views. Export as video and feed to Astra or Opus 5.5 to restyle, redesign, reimagine etc Try the capture app and Echo-3: spaitial.ai/echo-3 Record with web app: app.spaitial.ai

Echo-3 is out today! It's SOTA for world reconstruction while being metric accurate. I can't wait to see what you create with it.

The barrier to entry for 3D keeps plummeting. I’ve seen a lot of people pairing Astra with Blender for scans, but I think this will be stronger and much more photoreal. Not to mention all the applications this opens up for Physical AI.

Today, we're launching Echo-3, our world model for reconstructing real spaces. Key idea: treat reconstruction as conditional generation. The outputs are photorealistic 3DGS, point clouds, and meshes at metric scale -- only from a short iPhone video. We believe this is an important step for physical AI, which is bottlenecked by real-world 3D data. When any phone can produce a metric digital twin, capture scales with phones rather than expensive scanning rigs, for robotics as much as for construction and real estate. Echo-3 is also available via API: photos or video in, 3D worlds out. Check it out!

Happy to share that our new world model Echo-3 is out! Scan any place with your phone and our model generates a world for you to explore and share with others Had a lot of fun scanning houses and simulating robots in them and watching them explore the place 😄

🌍 Introducing Echo-3, a new world model enabling the most accurate reconstructions of real spaces to date! From a quick phone video of my daughter’s room, Echo-3 built a 3DGS model and restyled the whole house with her favorite fairy tales 🚀✨. Get the app and try it out!

10 minutes with an iPhone, and this gorgeous craftsman house is now a 3D world you can walk through! It still blows my mind how easy Echo-3 makes this. Go capture your favorite space 🙂 spaitial.ai/echo-3

I finally got my hands on @SpAItial_AI’s Echo. Here are my first 3 tests with just a single reference image. An outside urban area, a hotel room, and an expansive lake. I also toggled on the point view. None of these use Echo 2 high quality. What do you think? #worldmodel #3dgs

When triangles strike back as splatting primitives, I wondered: how well do they work on meshes, where traditional differentiable rasterizers are designed to excel? There’s still a gap—but Elastic Triangle Splatting is closing it. Interactive results: shenhanqian.github.io/ets

Elastic Triangle Splatting

Elastic Triangle Splatting explores kernel properties by two complementary tasks. Shape reconstruction (top) deforms a spherical triangle mesh into an accurate surface. Novel-view synthesis (bottom)...

The synced map to world is one of the coolest feature of our viewer. I had fun building this out 😀 You can click anywhere on the map to jump to a point in the world World movement is tracked in real time on map Gives a really nice experience! shoutout to @playcanvas

Large, consistent, and high-quality 3D worlds from simple iPhone recordings. Works for multi-room scenes, fills missing gaps consistently while maintaining high quality, and it’s super easy to use. Now in beta with partners and coming soon to the SpAItial API. Link to the scenes in the comments so you can navigate this world yourself 👇🏽
