Both models had something in the place a handle belongs, and against a
photograph neither was a handle.
The tankard's was a flat box put through `bendGeometry` and then pushed
clear of the body by a hand-derived offset. Measured, the result stood
7 mm proud of a body 47 mm in radius, with the rest buried in the stave
wall -- no finger gap at all, which is why it read as a plank glued to the
side. The offset formula did not describe what `bendGeometry` does to the
geometry, and rather than deriving a better correction for a curve that
cannot be inspected, the handle is now an actual arc from
`arcBarGeometry`, specified by the two things that matter: where the ends
land and how far the belly stands off. It now stands 24 mm clear. The
proportions go with it -- the reference is a fist-sized vessel, ours was a
beaker.
The lantern's was a horizontal `bandGeometry` ring sitting on the flue: a
suspension eye, not a bail. A lantern is defined by being carried, so the
bail is the first thing the eye looks for. It is now a vertical arch whose
sweep runs about 20 degrees past a half circle at each end, which turns the
ends downwards and outwards so they cross the roof cone instead of sitting
tangent to it -- a clean half circle was rejected by the support check as
floating, correctly.
Removing the ring stranded the tongue that used to join it to the flue, and
leaving it in place produced the z-fight: its sides sat at z = +-0.00488
against the bail's +-0.00512, a quarter of a millimetre apart across the
whole apex. A bail that reaches into the roof needs no strap to hold it on.
Worth recording how that one was found. The first guess was that
`arcBarGeometry` self-intersects once the sweep passes PI. Building the
bail in isolation across six sweeps and segment counts gave 0 overlaps
every time, which killed the theory before any time went into fixing the
wrong thing.
27 models, 17433 triangles, all checks pass, 0 floating cases.
Two rules were missing, and each one had been quietly failing for a while.
The first is structural. Every check in this repo asked about surfaces --
winding, coplanarity, triangle counts -- and none of them could see a piece
of a model hanging in the air with nothing holding it up. A chest lid
separated from its chest passed everything we had. scripts/support.ts
voxelises the model, finds the connected components of occupied space and
requires each one to reach the floor; scripts/audit.ts runs that across
default, min, max, both sweep ends, actions and the midpoint of a morph, so
a variation cannot break what the default gets right. That audit started at
22 failing cases: the bell and the sign had no supporting structure at all
and now have a frame and a post, the lantern was in four pieces, the sack's
collar floated above its body, the basket's fruit hung level with the rim
instead of resting on the base, and the ladder's rungs were sized by a
formula that disagreed with where the rails actually were. It now reports 0.
The second is that we had no target. The feedback loop was an offline
render of our own output, which can only answer "is this broken", never
"is this right". Given a reference photograph of a cask, five defects were
obvious in seconds that three rounds of self-review had missed: four hoops
where there should be six, no rivets at all, a chime cut so shallow it did
not read, and a stave count low enough to leave a visibly polygonal
silhouette. All four are fixed here.
Two things the rivets taught us, both kept as comments rather than as
scars: a stud that tapers outward tilts its side normals back towards the
axis, which the radial check correctly reports as reversed winding -- a
real rivet head flares, so the honest shape is also the passing one. And
once seated deep enough to look right, the stud's buried inner cap falls
inside the shell the check inspects, so it is not generated at all, exactly
as bandGeometry already declines to build the inside of a hoop.
27 models, 16973 triangles, all checks pass, 0 floating cases.
The kit is going public, so everything a reader sees is now English:
27 model sources, the core vocabulary, meta.ts (titles, descriptions and
every slider label), the viewer UI, all script output, REFERENCE.md and
the READMEs.
Rules applied: only comments, doc comments and human-facing strings were
touched. Identifiers, numbers, logic, registry item ids, part names and
material slot names are unchanged — those are a published contract and
were already English.
Verified rather than assumed: for all 53 changed .ts files the code
skeleton (source with comments stripped and string contents replaced by a
placeholder) is byte-identical before and after. Full gate is green —
typecheck, registry conformance, ~510 model checks, GLB round trip and a
production build.
Also fixed here:
- index.html and viewer.html were missed by the translation pass because
the file list only covered .ts/.md/.css. Both had lang="tr" and Turkish
titles.
- The viewer formatted triangle counts with toLocaleString('tr-TR'), which
prints 15.425 rather than 15,425.
- REFERENCE.md's model table header did not match what
scripts/catalog-table.ts emits, so the next regeneration would have
silently changed it. Aligned to the generator.
- Removed scripts/probe.ts and scripts/zdiag.ts; they were throwaway
diagnostics that got committed by accident.
Modeller (13 → 26): chest, bench, torch, lantern, bell, sign, hay bale,
sack, broom, tankard, book, phial, coin pouch. Kürek, çapa ve yaba
render'lara bakılarak yeniden yazıldı.
core:
- createKitModel artık tipli `actions` ve `update(dt)` taşıyor
- BuiltPart.extras: bir parça birden çok materyal yuvası kullanabiliyor
(sandığın kapağı = meşe tahta + demir kayış, birlikte dönmek zorunda)
- BuiltPart.origin: parça başına dönme merkezi (menteşe, sarkaç)
- bendGeometry / roughenGeometry / mottleGeometry
- 5 yeni materyal yuvası: steel, brass, straw, cloth, leather, glass
- bandGeometry({ inner }) — serbest halkalar kapalı katı olabilsin
my-registry/meta.ts: katalog metadata'sı artık build.ts ve viewer için
tek kaynak. Doğrulama modelle metadata'nın uyuştuğunu denetliyor ve bu
eklendiği gün dört modelde gerçek bir sapma yakaladı.
Doğrulama (~500 kontrol):
- metadata uyumu, eylem semantiği, kare hızı bağımsızlığı
- scripts/render.ts: tarayıcısız yazılım rasterleyici. Bütün doğrulama
geometrikti; "bu kürek küreğe benzemiyor" diyebilmek için modele
bakmak gerekiyordu
- scripts/verify-glb.ts: dışa aktar → geri oku → karşılaştır
GLB dışa aktarımı: viewer düğmesi ve toplu CLI aynı kodu kullanıyor.
Viewer:
- parça paneli (solo/izole) ve materyal yuvası paneli (canlı renk override)
- kit görünümü: 26 model tek sahnede, ölçek ve ton tutarlılığı için
- configure() sonrası gölge bayraklarının düşmesi düzeltildi
