JavaScript ArcGIS SunLighting用法及代碼示例

AMD: require(["esri/views/3d/environment/SunLighting"], (SunLighting) => { /* code goes here */ });

ESM: import SunLighting from "@arcgis/core/views/3d/environment/SunLighting";

自從：用於 JavaScript 4.23 的 ArcGIS API

SunLighting 類允許您將場景中的照明更改為陽光。燈光的位置設置為太陽的位置。

例子：

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

  map: new Map({
    basemap: "satellite",
    ground: "world-elevation"
  }),
  environment: {
    lighting: {
      type: "sun"    // autocasts as new SunLighting()
    }
  }
});

隻要 type 屬性更改，照明可視化就會更新：

view.environment.lighting = {
   type: "sun",
   directShadowsEnabled: true    // autocasts as new SunLighting({ directShadowsEnabled: true })
}
