Case explorer

Case-by-case comparison

All 26 cases individually: the original source video next to the interactive 3D views of all eleven runs. The metrics on each card are defined in the methodology; the aggregate is in the results.

In brief: Every single case can be examined here: the original video next to the rotatable 3D reconstructions of all eleven runs. Unfamiliar terms are explained in the glossary.

All 26 cases in detail

Each case can be expanded: at the top the original source video, below it one interactive 3D view per model – one click loads the rotatable model (mouse to rotate, wheel to zoom). Divergent interpretations stay visible too; this way every result can be checked directly against the original.

All 3D models shown are AI reconstructions from the technical drawings — not the original models. They are our own works derived from the non-protectable dimensional facts of the drawings; we do not show the authors' reference models – the exception is our own case 900 below.

Case 900 · bearing block – the case shown in full

We designed this case ourselves: a bearing block, created as our own work in the same drawing style as the rest of the corpus and run through the complete measurement chain. We decided not to publish works of third parties – in return we show our own case in full: drawing, reference model, and reconstructions. The AI reconstructions of case 900 can be found in the case card above and in the gallery on the home page. As an example we additionally show the complete measurement log of an agent for this case (Claude Code · opus-5 · run 1, redacted edition) — the self-documentation that traces every build decision back to a piece of evidence.

Drawing and reference model are our own works of the institute; that is why we show them in full – unlike the cases of third parties. The metrics of the AI reconstructions are in the case card for case 900.
