DelaunayCoverLayer

DelaunayCoverLayer renders a terrain surface from the same weather-station triangulation used to interpolate a WindField. Each triangle follows measured station elevations and is colored by its average height. It recreates the elevation surface in the original deck.gl wind showcase.

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

const layer = new DelaunayCoverLayer({
  id: 'wind-terrain',
  windField,
  elevationScale: 14,
  lowColor: [17, 34, 49, 220],
  highColor: [102, 151, 127, 235]
});

Properties​

  • windField: A WindField returned by createWindField.
  • elevationScale: Multiplier for each station elevation.
  • lowColor, highColor: RGBA colors interpolated by average triangle elevation.

Sub-layers​

  • terrain: A SolidPolygonLayer containing the station Delaunay triangles.

See the Wind Map example.
