DelaunayCoverLayer

Work in progress

The station-surface appearance and API may change. Its native triangle primitive works on WebGL2 and WebGPU; image-derived mountain terrain remains dependent on upstream TerrainLayer support.

DelaunayCoverLayer renders one elevation-colored polygon for each triangle in a shared WindField. It visualizes the real station interpolation hull; it is not the same as the smoothed image-based mountain surface rendered by ElevationLayer.

Import​

import {DelaunayCoverLayer} from '@deck.gl-community/geo-layers';

Example​

const stationSurface = new DelaunayCoverLayer({
  id: 'wind-station-surface',
  windField,
  elevationScale: 24,
  lowColor: [17, 34, 49, 220],
  highColor: [102, 151, 127, 235],
  opacity: 0.32
});

Properties​

  • windField (WindField, required): shared robust station triangulation and forecast.
  • elevationScale (number, default 1): station-height multiplier.
  • lowColor (Color, default [17, 34, 49, 220]): fill color for the lowest stations.
  • highColor (Color, default [102, 151, 127, 235]): fill color for the highest stations.
  • Standard deck.gl CompositeLayer properties, including opacity and visible.

Sub-layers​

  • terrain: native GLSL/WGSL triangle geometry containing the station-index Delaunay triangles.

The triangulated station surface, elevation scaling, and height-based colors render on both WebGL2 and WebGPU. This surface is distinct from the smoothed image-based mountain terrain.

Use the example's Delaunay station surface control to inspect the triangulation independently of the smoothed mountains. See the wind showcase guide.
