用法说明

SceneView.environment函数(或属性)的定义如下：

environment Accessor

指定视图中环境可视化的各种属性。当环境的任何属性发生变化时，SceneView 将自动重绘。

修改灯光：

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;

设置背景：

// 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
  }
});

改变场景中的天气：

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

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