Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/city-building.mjs';

const cityBuilding = createAsset();
scene.add(cityBuilding);                      // rests on y = 0, front faces +Z

// 'door' pivots on its hinge: -100° to 0° around y
cityBuilding.getObjectByName('door').rotation.y = THREE.MathUtils.degToRad(-100);

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/city-building.mjs';

export function CityBuilding() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import city-building.glb (download below). Moving parts are separate nodes, pivoted on their hinge.
$CityBuilding/door.rotation_degrees.y = -100

// Import city-building.glb with glTFast (com.unity.cloud.gltfast).
transform.Find("door").localEulerAngles = new Vector3(/* y: */ -100, 0, 0);

Knobs

Knob	Type	Values	Default	What it does
`floors`	range	1 to 8, step 1	`4`	Number of storeys, 1 to 8. The ground floor is 4.2 m with shops (3.4 m without), upper floors 3.1 m, so 4 floors with shops is about 13.5 m to the cornice.
`facade`	choice	`brick` `stucco` `concrete` `glass`	`brick`	brick (red-brown with stone lintels and sills, pre-war tenement), stucco (pastel render with shutters, European old town), concrete (grey ribbon windows, post-war modern), glass (curtain wall with metal mullions, new office or condo).
`width`	range	2 to 6, step 1	`4`	Frontage in window bays of 3.2 m: 2 is a narrow townhouse (6.4 m), 6 a big block (19.2 m). Depth is always 9.6 m so buildings line up along a street.
`shopfront`	toggle	on / off	`true`	Ground floor of shops: big glass windows that glow at night, a sign band without text and striped or plain awnings in seeded colours. Off gives a residential ground floor with a plinth and a front stoop.
`balconies`	toggle	on / off	`false`	Balconies on a seeded set of front bays above the ground floor: iron railings on brick and stucco, glass balustrades on concrete and glass.
`roof`	choice	`flat` `water tank` `garden` `pitched`	`flat`	flat (parapet, stair hut, AC units and vents), water tank (flat roof with a wooden water tower on legs, New York style), garden (planters, small trees and a pergola), pitched (slate or tile gable roof with dormers and chimneys).
`seed`	range	1 to 999, step 1	`7`	Variation seed: wall and trim colours, window layout and blinds, which windows are lit at night, shop awnings and sign colours, balcony pattern and roof clutter. Every seed is a different building.
