SplatStroll Avatar in 3 Steps

Get a walkable 3D space in just 3 steps.

1

Generate Data

Create 3D Gaussian Splatting data using your favorite tool — smartphone apps, PC software, and more.

2

Build the Space

Drag & drop a 3DGS file into the browser — it instantly becomes a walkable 3D environment.

3

Walk

Your avatar takes a stroll through the scene on your behalf.

Your Travel Photos, Your Garden, Your Favorite Café

Your memories become 3D spaces. Just drag & drop your 3DGS data (.ply / .sog / .spz / .rad).
No upload needed — everything is processed locally for complete privacy.

  • Walk through landscapes you captured on your travels
  • Bring your avatar to memorable places
  • Re-experience the atmosphere that photos and social media can't convey
Tip: Not sure how to create 3DGS data? Apps like Scaniverse and Polycam make it easy — even on a smartphone.

Key Features

Not just a viewer — a walkable 3D experience.

🚶

Auto-Stroll

The avatar walks on its own — navigating steps, avoiding walls, and finding scenic spots as if truly taking a stroll. The camera automatically switches to cinematic angles.

🎮

Manual Controls

Move freely with WASD / arrow keys, rotate the camera with your mouse. Jump is supported too. Touch controls available on mobile.

👤

Bring Your Own Avatar

Upload a VRM avatar to explore scenes with your own character. Real-time facial expressions, blinking, and eye tracking included.
* VRM 0.x / 1.0 supported (VRM 1.0 recommended)

📷

Photo Position Overlay

Visualize capture positions in 3D space. COLMAP data is shown as frustums; transforms.json converted from Metashape 360° ERP images is shown as spheres. Instantly see where each photo was taken.

🎨

Image Filters & Depth of Field

Transform scenes into anime-style visuals with the Kuwahara + posterization filter. Add cinematic bokeh with real-time Depth of Field (DoF).

⚡

Runs in the Browser

No installation needed. WebGPU-enabled browsers get GPU acceleration for extra speed. Falls back to CPU rendering when WebGPU is unavailable.

Tips

Handy tricks to get more out of SplatStroll Avatar.

Showing capture positions: You can visualize the capture positions of photos used to train a locally loaded 3DGS scene. Drop your COLMAP files (cameras.txt / images.txt) or a transforms.json to display capture positions in the scene. COLMAP data appears as frustums; ERP transforms.json appears as spheres. You can generate transforms.json from Metashape 360° camera data using the metashape_360_lfs script. Enable "Show photo positions" in the Camera menu and use the on/off toggle to show or hide them.
