About this app

Splat Camera turns your phone into a 3D scanner: walk around an object, and the app trains a 3D Gaussian Splatting model right on the device. No cloud, no account — the app has no internet access at all, so your photos and models never leave the phone.

HOW IT WORKS
1. Capture the object. The app tracks the camera position and keeps only the frames that help.
2. Start training. The model is computed on your phone's GPU; progress lives in a notification, and a run can be paused and resumed.
3. Watch the model in the 3D viewer — even while training runs — and save it as a standard .ply file that opens in popular Gaussian splat viewers.

CAPTURE
• Video mode: aim at the object and a coverage map shows which sides are already captured, while the app saves one frame per viewpoint on its own.
• Photo mode: manual shots, with thumbnails of taken frames shown right in the viewfinder — a gap in coverage is visible immediately, not after training.
• Auto shutter: a new frame is taken only once the camera has moved enough to add something.
• Blurred frames are rejected automatically.

IMPORT
Already have footage? Import photos or a video from your gallery — built-in photogrammetry recovers the camera poses, again with no server involved.

QUALITY
• Poses are refined against the photos themselves (bundle adjustment) before training — less ghosting and blur.
• Honest scoring: quality is measured on frames the model never saw during training.
• Point eraser: wipe stray points from the starting cloud before training.
• Subject-only mode: confine the model to a box, so you train the object, not the room around it.
• Three presets: a quick result in minutes, or maximum quality in hours.

FULLY OFFLINE
Everything is computed locally. Training is heavy work: the phone will get warm, the app throttles itself using the thermal sensor, and an interrupted run resumes from its checkpoint. Plugging in for training is a good idea.

REQUIREMENTS
• A device that supports ARCore (Google Play Services for AR).
• Free storage: a scan with its photos and model takes hundreds of megabytes.

TIPS FOR A GOOD MODEL
• Walk around the object rather than turning the phone in place.
• Move slowly and smoothly: less motion blur means a sharper model.
• Even, diffuse light beats glare; transparent and mirror-like objects are the hardest.
