@urban-toolkit/autk-core / TriangulatorRaster

Class: TriangulatorRaster

Defined in: triangulator-raster.ts:24

Builds textured mesh geometry for GeoTIFF raster layers.

TriangulatorRaster turns the source collection bbox into a single quad in local XY space. The four corners are shifted by the supplied origin so the raster aligns with the rest of the layer stack, and the quad is emitted with UVs spanning [0, 1] to match normalized texture coordinates.

Constructors

Constructor

new TriangulatorRaster(): TriangulatorRaster

Returns

TriangulatorRaster

Methods

buildMesh()

static buildMesh(geotiff, origin): [LayerGeometry[], LayerComponent[]]

Defined in: triangulator-raster.ts:35

Builds a single textured quad covering the raster bounding box.

Parameters

geotiff

FeatureCollection<Geometry | null>

Raster feature collection whose bbox defines the quad extent.

origin

number[]

World-space origin subtracted from each corner to form local coordinates.

Returns

[LayerGeometry[], LayerComponent[]]

A tuple of quad geometry and matching component metadata.

Throws

Never throws. When bbox is missing, returns empty arrays with a console warning.

Example

const [meshes, comps] = TriangulatorRaster.buildMesh(rasterFC, origin);
