用法說明

SceneView.environment函數(或屬性)的定義如下：

environment Accessor

指定視圖中環境可視化的各種屬性。當環境的任何屬性發生變化時，SceneView 將自動重繪。

修改燈光：

let view = new SceneView({
  map: map,
  container: "viewDiv"
});

// Set the light source position to reflect the current sun position at that time
view.environment.lighting = {
  type: "sun",
  date: new Date("January 1, 2022 12:00:00 UTC")
};

// Change the lighting to virtual, so that everying in the scene is nicely lit:
view.environment.lighting = {
  type: "virtual"
};

// Enable displaying shadows cast by the light source
view.environment.lighting.directShadowsEnabled = true;

設置背景：

// Set a background color
let view = new SceneView({
  container: "viewDiv",
  map: map,
  environment: {
    background: {
      type: "color",
      color: [255, 252, 244, 1]
    },
    starsEnabled: false,
    atmosphereEnabled: false
  }
});

改變場景中的天氣：

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

  map: new Map({
    basemap: "satellite",
    ground: "world-elevation"
  }),
  environment: {
    weather: {
      type: "cloudy"   // autocasts as new CloudyWeather()
    }
  }
});
