SnowyWeather | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The SnowyWeather class allows you to change the weather conditions in the scene to snowy weather.

scene-atmosphere

Example:

let view = new SceneView({
  container: "viewDiv",

  map: new Map({
    basemap: "satellite",
    ground: "world-elevation"
  }),
  environment: {
    weather: {
      type: "snowy",
      cloudCover: 0.8,
      precipitation: 0.3,
      snowCover: "enabled"   // autocasts as new SnowyWeather({ cloudCover: 0.8, precipitation: 0.3, snowCover: "enabled" })
    }
  }
});

The weather visualization updates as soon as the property changes:

view.environment.weather = {
   type: "snowy",
   cloudCover: 0.4,
   precipitation: 0.3   // autocasts as new SnowyWeather({ cloudCover: 0.4, precipitation: 0.3, snowCover: "disabled" })
}
