🏃♂️💨 World × WebGPU × runtime physics × motion-matched parkour.
In a browser tab. Anywhere on Earth. 🌍
@arrival_space_
New adaptive locomotion coming to @arrival_space_
Motion matching built from scratch for the web
predicting movement and picking the best fit from 200+ Mixamo animations.
Automatic ledge grabbing on any world geometry, including splats.
Built a tropical island in @arrival_space_ with Vibes
Spent most of the time telling the AI the shadows were floating.

北海道・新得町にある「小笹川橋梁」の3DGSワールドを公開しました！
旧根室本線の鉄道遺産。石造りのアーチの上には、かつて列車が走っていた線路跡が残っています。ワールド内を歩くと、ちょっとした冒険気分に( ^ω^ )
今回はOSMO360で撮影した約16分の動画をSpirulaで3DGS化。
・Quality：medium
・学習：30,000 steps／3M splats
・トレーニング：約17時間
Qualityをhighにすれば、もっときれいになりそう。
Arrival.Spaceでのコリジョン生成に苦戦しましたが、ようやく成功！LODも設定し、スマホでは軽量版を表示しています。

私たちは東京に行きます!🇯🇵 10月23日（金）のHoloLab Conference 2026でお会いしましょう！
パートナーであるHoloLabチームの皆さまのサポートに心から感謝しています！日本のクリエイターやパートナーの皆さまにお会いできるのが楽しみです。
その週にお会いできる方は、ぜひDMでご連絡ください！
🤖 Made with AI
What started as playing around with browser synths turned into a full rhythm game on @arrival_space_ 🎹
Every note is generated in code, and Claude Opus 5.5 playtested every level to get the difficulty just right.
Turn the sound on 🔊

Arrival.space のバイブコーディングを使って、騎乗できる馬をスペースに配置して遊んでました。色々選べるようになっていたのでGPT-6 Astraで
馬のギャロップがちゃんとできてる😆
捏造ではなく、実際にバーレーン要塞の周りの牧場で馬を借りて、遺跡で乗馬体験をすることができます
この馬もバーレーンで良く飼育されている「アシル・アラビア馬」を再現するように指示しています
人や動物なども含めて遺跡景観だと思うので、気軽に再現できるのは没入感が増して良いですよね😊
I finally found a use case for AI.
Destroying our office.
Drop in a photo. Ask AI to model it and make the furniture pushable. Walk in. Make a mess.

This started with a Gaussian Splat from @Schindelar3D and a few prompts.
Astra + Opus 5.5 handled the game dev, generating assets through @Blender and accessing our Splat relighting capabilities directly.
No additional app opened. All inside the browser and ArrivalSpace.
What would you add next?
Apollo 11, simulated at full Earth-Moon scale in the browser.
Real mission sequence, staging + docking, Google 3D Tiles for Earth, original NASA audio, and you can walk on the Moon.
Built on arrival.space. and @playcanvas

“This is not a game character. It’s me.”
20 minutes from iPhone capture with SplatKing and processing in Splatjs to a photorealistic, animated avatar walking through Gaussian Splats. Try now.
See you at IBC2026 in Amsterdam
Depth occlusion in WebXR in @playcanvas , no install.
A gaussian splat on my desk, feels strange to touch with my own hands...
Open on a Quest 3 / MIT Licence
github.com/arrival-space/pla…
Per-pixel per-eye depth from the Quest 3, in the browser. No AI — straight off the depth sensors.
Because it's sampled per eye, it lands on the hand in stereo — surreal, it stops reading as an overlay and starts feeling real.
WebXR, no native code.

train gaussian splatting straight in the browser with Splat.js. SfM included, open source, and MIT Licensed.
Video from @PixelBilly and @arrival_space_
A single static 3DGS scan → animated + relit.
Rig once, apply any Mixamo animation, and reuse the same rigging data for per-splat relighting — no proxy mesh.
The result: captured humans that can become avatars or NPCs with dynamic lighting.
@arrival_space_ #GaussianSplatting
3DGS scan taken from scan-studio-iris
superspl.at/scene/965e24f5
Global #GaussianSplatting rendering in the browser.
Inspect a splat in full detail — then zoom all the way out to #Space.
This is running in @arrival_space_ with our new Cesium/Google tile renderer, atmospheric simulation, and time-of-day lighting.
