You've probably seen Meta's Hyperscape — the app that lets you walk through photorealistic 3D scans of real places. It looks incredible. But it's a closed system. You can only access it through their app. You don't get the files. You can't embed it. You can't share it outside Meta's ecosystem.

I wanted to build something that does the same thing — but open. Any device. Anywhere. Just a link.

What it does:

• Open a link on your Quest → you're standing inside a real captured space
• Walk around with full VR locomotion — not just looking around, actually moving through the space
• Teleport to different points in the scene
• Collision detection — you can't walk through walls or furniture, it feels real
• Snap turning for smooth navigation
• Same link works on your phone, laptop, tablet — any device with a browser

What surprised me:

• Quest browser handles it better than expected — the bottleneck is GPU, not the browser
• The same URL works everywhere — no separate VR build, no "VR version"
• WebXR is solid enough for real experiences, not just demos

How it compares to Hyperscape:

• Hyperscape: Closed ecosystem, app only → This: Open, any browser
• Hyperscape: Quest 3/3S only → This: Any device
• Hyperscape: No access to your files → This: Your files, your server

Try it on your Quest:

  1. Open the browser on your Quest
  2. Go to: https://mirador3d.com/en/v/tufia-test
  3. Click the VR button
  4. You're standing in a village in Gran Canaria
  5. Use the controller to teleport and walk around

Same link works on your phone if you don't have a headset handy. Happy to answer questions.

• Hyperscape: No teleport, no collisions → This: Full locomotion with collision detection

I'm not saying this is better than Hyperscape. Meta has thousands of engineers and unlimited resources. But the fact that you can do this through a browser — walk through a real space in VR with teleport and collisions, on any device, just by clicking a link — that surprised me.

I built a web-based Gaussian Splatting viewer that runs on a €200 Android phone — here's what I learned

Hey everyone. I've been working on a web-based Gaussian Splatting viewer for the last few months and wanted to share some findings.

Make a viewer that works on any device, including budget phones, without plugins or native apps.

- SparkJS 2.0 for rendering
- Progressive streaming via chunked RAD files
- HTTP Range requests from Cloudflare R2
- Adaptive quality system that detects GPU capabilities in real-time

Real-world results (tested on actual devices):

Scene Desktop (RTX 3070) Xiaomi 15 Ultra Redmi Note 11 (€200)
Tufia (8.5M splats) 60 fps 55 fps 40 fps
XGrids Demo (12M) 60 fps 45 fps 30 fps
50M splats 60 fps 25 fps 15 fps
100M splats 55 fps 15 fps 8 fps

What I got wrong:

1. Optimized too early. Spent weeks on custom compression before realizing `build-lod --rad-chunked --max-sh=3` already hit the sweet spot. The tooling is better than I expected.

2. Ignored the data problem. Users were uploading raw 500MB PLY files and wondering why nothing loaded. Had to build the conversion step into the workflow.

3. Assumed all phones are equal. They're wildly different. The adaptive quality system exists because of this mistake.

What I learned:

- Streaming > monolithic files. Progressive loading changes the UX entirely.
- `--max-sh=3` is the sweet spot for mobile. Higher SH bands have diminishing returns on small screens.
- The web is underrated as a platform for this. More people can click a link than download an app.

Happy to answer questions about the technical details. Live demo:
