Brick Scene Game Scanner
Turns a walk-around capture of a brick model into a destructible voxel level that users can set rules for and play immediately.
Brick Scene Game Scanner is a mobile app for families and indie creators that turns tabletop brick models into destructible voxel levels. Users walk around a castle, spaceship, or maze and capture it from all sides; the first screen shows a walkable 3D scene and flags areas with unstable recognition that need another pass.
They can then assign a few bricks as a door, enemy spawn point, or explosive and immediately test the level to see whether collapses and paths work as expected. After changing the model, they only need to rescan the affected area, while the app keeps the rules already set. It does not replace professional modeling; it turns a physical draft that children and designers have already built into a first playable level.
Why now
On July 15, 2026, Voxatron returned to Hacker News; in the signal snapshot observed at July 16, 2026, 00:33 UTC, the post had 52 points, 16 comments, and ranked 17th, refocusing discussion on destructible voxel worlds and user-made games. S1 Apple already provides walk-around capture guidance, missing-area prompts, and on-device 3D reconstruction in iOS, so the hardest scanning step in turning a physical model into a playable prototype can start from existing platform capabilities.

Target user
Children or parents who have just built a castle, spaceship, or maze and want to turn it into a game right away. Indie creators can use it when a paper level is not worth formal modeling yet, but they need to test paths and destruction.
Minimal entry point
Limit the first version to iOS and one tabletop model. Use RealityKit Object Capture for guided capture and 3D reconstruction, support only door, spawn point, and explosive markers after voxelization, then test whether a local rescan can retain rule anchors.
Punching above its weight
Record short before-and-after videos of a scanned tabletop castle collapsing, with a link to play the level. Share them in TikTok, YouTube, Reddit, and Discord communities used by brick MOC, voxel-game, and indie-game creators. The process itself is the demo, so no content media needs to be built first.
Competitors & gaps
- RealityScan MobileGoogle
- RealityScan Mobile can generate high-fidelity 3D models with a phone, but stops at general scan outputs. It does not turn models into destructible levels or manage the link between game rules and local rescans.
- BrickitGoogle
- Brickit identifies loose bricks and recommends builds, serving the question of what can be built from available parts. This product focuses on digitizing completed models, placing rules, and testing them immediately.
How it makes money
Offer one project free, then charge a monthly subscription for multiple projects, local rescan history, and shareable level exports.
The case against
The strongest case against this is that scan stability may fail: bricks often have repeated studs, smooth reflective surfaces, and heavy occlusion. If local reconstruction drifts, existing doors, spawn points, and explosives will be hard to keep reliably in place.
