FoggyWeather | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The FoggyWeather class allows you to change the weather conditions in the scene to foggy weather.

scene-atmosphere

Example:

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

  map: new Map({
    basemap: "satellite",
    ground: "world-elevation"
  }),
  environment: {
    weather: {
      type: "foggy",
      fogStrength: 0.8      // autocasts as new FoggyWeather({ fogStrength: 0.8 })
    }
  }
});

The weather visualization updates as soon as the property changes:

view.environment.weather = {
   type: "foggy",
   fogStrength: 0.4   // autocasts as new FoggyWeather({ fogStrength: 0.4 })
}
