EXP.01 — Capture → Engine

A coloured laser-scan point cloud of a house interior turning slowly while a section plane drops through the floors

01 / 07 · THE CAPTURE · CLIP

A house, as 1.47 billion measured points.

54 laser-scan stations, inside and out. The scan is the ground truth; everything after it is judged against it.

Shown at a fraction of a percent of full density.

Raw scan mesh of a great room and kitchen, gray and noisy

The same view as a clean real-time engine render

02 / 07 · SAME CAMERA · COMPARE

Raw scan in, engine-clean geometry out.

Drag the line. Left is the scan mesh; right is the rebuilt room in Unreal Engine, from the same camera.

Every wall, cabinet and opening is modelled as clean geometry and placed where the scan says it is.

Four interior views, each wiping from the scan mesh to the engine render at the same camera

03 / 07 · ROOM BY ROOM · CLIP

The same test, in every room.

Each review view exists as layers: scan, mesh, render. A reviewer flips between them and marks what does not match.

The first zone closed 34 of 34 review items before it was accepted.

A slow camera move through the entry hall and stair of the rebuilt house, running in the packaged build

04 / 07 · REAL TIME · CLIP

A packaged build, not a render.

Captured from the standalone build: about 10 million triangles at roughly 92 frames per second on a desktop GPU.

Window backdrops are placeholders and the lighting is a first pass.

Correlation plot: control pairs of scan stations agree at zero offset, exterior against interior pairs agree at plus 26.3 centimetres

05 / 07 · THE FINDING · PLATE

The checks found an error in the scan itself.

One door, scanned from both sides, did not line up. Three independent methods agreed: the exterior stations sit 26.3 cm above the interior ones.

The build is paused until that correction is applied. Building faster on a wrong datum is not progress.

The same entry-hall camera route rendered by three successive versions of the model, from early blockout to the current build

06 / 07 · HOW IT IS RUN · CLIP

Agent crews, run like a production team.

Builders work in versioned passes against a written checklist. A separate verifier, with no stake in the pass, reads the result against the scan. Each asset has one owner.

Nine versions shipped in about 44 hours of the latest round. Here: the same route in September, and now.

What works, and what does not yet.

The aim is throughput with a bar: a capture should become an engine environment as a repeatable system, with the supervision written down.
