@urban-toolkit/autk-core / TriangulatorBuildings

Class: TriangulatorBuildings

Defined in: triangulator-buildings.ts:39

Builds extruded mesh geometry for OSM-style buildings.

Each feature is expected to contain a GeometryCollection whose entries are matched by index against feature.properties.parts. For every supported part geometry, the triangulator converts world coordinates into local XY space, resolves wall heights from part metadata, and emits mesh chunks with feature component counts. Roof geometry is delegated to triangulator-roofs.

Example

const [mesh, components] = TriangulatorBuildings.buildMesh(buildings, origin);

Constructors

Constructor

new TriangulatorBuildings(): TriangulatorBuildings

Returns

TriangulatorBuildings

Methods

buildMesh()

static buildMesh(geojson, origin, allowZeroHeightBuildings?): [LayerGeometry[], LayerComponent[]]

Defined in: triangulator-buildings.ts:51

Builds extruded building geometry for an OSM-style building collection.

Parameters

geojson

FeatureCollection

Source building feature collection.

origin

number[]

World-space origin used to convert coordinates into local XY space.

allowZeroHeightBuildings?

boolean = false

When true, parts with no height metadata get a random fallback height.

Returns

[LayerGeometry[], LayerComponent[]]

A tuple of mesh chunks and per-feature component metadata.

Throws

Never throws. Parts without height metadata are skipped (or given fallback height).

Example

const [meshes, comps] = TriangulatorBuildings.buildMesh(buildingsFC, origin);
