Port gates

A modular 4 m section of circuit-board city wall pierced by two port gates, each framed by a raised black bezel and hung with a warm-white connector tongue over gold contact fingers. Chip merlons run the crest, end pylons mark the snapping ends, and gold trace roads leave each mouth across the green board deck.

How it was made

The brief given to 1DesignTool's “3D object” template:

Port gates for the Circuit City kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It is a modular piece that snaps on a 1 m grid: give it a length in whole metres and put the origin at its snapping end, stated in meta.notes. This is one part of the Circuit City kit (Low-poly style, flat-lowpoly direction): The inside of a computer as a city. Use ONLY the kit palette, by name: board green #3a883a, gold traces #d0a225, black chips #151619, led colours #988e81, board green dark #235223, gold traces dark #8f7019, board green light #5db15d, gold traces light #debd63, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `ledColours` (0–1, default 0.5) for the kit's "LED colours" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale at the default parameters: 4.0 m long (X) x 3.132 m tall (Y) x 2.6 m deep (Z), with the board deck resting exactly on y = 0. It is a modular piece on a 1 m grid: the origin is at the -X snapping end (x = 0, y = 0, centred in depth, z = 0), the wall runs along +X, and the length parameter is in whole metres, so copies tile end to end. The front — the face with the LED status bars and the solder-pad row — faces +Z. Every full-length element (plinth, kerbs, base course, wall panel, cornice, trace stubs, bus lines) dies into the inner face of a half-width end pylon, and two abutting segments' half-pylons meet as one whole pylon, so the seam reads as a solid end tower. The merlon and solder-pad lattice is pitched at 0.5 m and held clear of both ends for the same reason. Assembly groups use plain dotted ids (portgates, portgates.wall, ...) because the kit's plan grammar has no hyphens; every mesh carries a circuit-city-port-gates.* id. Materials are named exactly after their Circuit City palette colour, and all twelve kit colours are used, so the GLB recolours as one; glb-lint reports 22 materials only because the runtime export path writes one material per mesh. ledColours (default 0.5) sets how many of the ten pips in each gate's status bar are lit: the lit ones take the emissive 'led colours' material, the rest stay 'black chips'. At 0 the bar is dark and the 'led colours' material is absent from the GLB; at 1 every pip is lit. length, wallHeight and gateCount rebuild the geometry in the viewer (1466 triangles at the smallest settings, 2970 at the largest), but the GLB holds the default values only. gateCount is clamped to what the segment can hold -- a gate bay needs a 1.8 m pitch, so a 3 m segment gets one gate whatever the knob says, a 4-5 m segment at most two, and three gates need the full 6 m. The exported model is 1844 triangles across 22 meshes, static (no animation clip), with no textures and flat normals baked into the geometry. glb-lint: 0 errors. Its overall verdict prints UNVERIFIED only because no requirements contract exists; the five heuristic warnings were reviewed and accepted -- the per-mesh duplicated materials from the export path, the deliberate nesting of bezels/buttresses/cornice into the wall, the deck and kerbs flagged as detached (they bed into the plinth below them), and the expected-1 m scale heuristic against a true 3.13 m wall. OBJ export is geometry only.
