CAPTURE ON YOUR PHONE. EXPLORE IN 3D.
Your video.
A scene in 3D.
Turn a short walkthrough into a scene
you can move around. Real Gaussian splatting.
01 / YOUR CAPTURE
Start small. Walk slowly.
Film one object or a room corner for 15–30 seconds. Walk around it, keeping it in frame. Use good light and the normal 1× camera.
Checking processor connection…
Processing takes minutes, not seconds. Your Mac must stay awake. Your phone only uploads the clip and displays the result.
What makes a good capture?
- Move sideways or in an arc. Turning the phone from one spot isn't enough.
- Keep the same surfaces visible across neighbouring frames.
- A textured chair or desk is easier than blank walls, glass or mirrors.
- Keep people and objects still. Avoid zooming and switching lenses.
- Use 1080p to keep the upload small. A complete room is harder than one corner.
More than a photograph.

A visual reconstruction, not a measured survey. Hidden surfaces may be missing or blurry. Existing 3D files stay on your device.
How this works & processor connection ＋
Video → cameras → Gaussian splats.
COLMAP matches details between frames to estimate the camera path. Brush then trains thousands of small, coloured 3D shapes to reproduce those views. Spark displays the result on your phone.
No LiDAR needed. This is an early experiment, with no dimensions or accuracy guarantee. A good capture can still fail.
A private prototype processor.
This version uses your connected Mac, connected through private Cloudflare storage. Video uploads are available while the processor and Mac are running. The connection link grants access: keep it private.
No processor connected? You can still open existing .ply, .splat, .spz or .ksplat files.
