@deck.gl-community/geo-layers

This module contains a suite of non-official deck.gl layers.

They can be quite useful in applications, however they are not officially supported by the deck.gl team, so use at your own risk.

Wind layers

Status: work in progress. The package includes reusable layers and interpolation utilities from Nicolas Belmonte's historical deck.gl wind showcase:

• WindLayer renders interpolated, speed-colored wind-direction arrows.
• ParticleLayer animates GPU-resident particles through the wind field using WebGL2 transform feedback or WebGPU compute, without per-frame particle readbacks.
• ElevationLayer renders the original elevation image as illuminated 3D mountain terrain.
• DelaunayCoverLayer renders elevation-colored station-triangulated terrain.
• DelaunayInterpolation samples or rasterizes the same field.
• parseWindData, triangulateWindStations, createWindField, getWindBounds, and sampleWindField load and interpolate the original station-major, 72-hour weather forecast.

import {
  createWindField,
  parseWindData,
  ParticleLayer,
  WindLayer
} from '@deck.gl-community/geo-layers';

const windField = createWindField(stations, parseWindData(weather, stations.length));

const layers = [
  new WindLayer({id: 'wind-arrows', windField, time}),
  new ParticleLayer({id: 'wind-particles', windField, time, numParticles: 100_000})
];

WebGL2 and WebGPU particle simulation are independently browser-tested. Wind arrows, state boundaries, station-triangulated terrain, and the original image-derived mountain terrain are portable with stable deck.gl 9.4.

See the wind showcase guide and standalone example.
