JavaScript ArcGIS VirtualLighting用法及代码示例

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

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

类： esri/views/3d/environment/VirtualLighting

继承: VirtualLighting > Lighting > Accessor

自从：用于 JavaScript 4.23 的 ArcGIS API

VirtualLighting 类允许您将场景中的照明更改为虚拟光。灯光的位置跟随相机并设置在相机后面，向左侧有一个小的偏移。

例子：

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

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

只要 type 属性更改，照明可视化就会更新：

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