ArcGIS API for JavaScript 中的 SceneLayer 是用于显示 3D 场景数据的图层类型,它支持多种数据格式(如点云、3D 模型等),并且可以在 3D 场景中进行交互。
以下是 SceneLayer 的基本用法:
1. 导入模块和创建 SceneView 对象
```javascript
require([
"esri/views/SceneView",
"esri/layers/SceneLayer",
"dojo/domReady!"
], function(SceneView, SceneLayer) {
var view = new SceneView({
container: "viewDiv",
map: map,
camera: {
position: {
latitude: 34.057,
longitude: -117.196,
z: 1000 // 以米为单位
},
tilt: 65 // 以度为单位
}
});
});
```
2. 创建 SceneLayer 对象并添加到地图中
```javascript
var sceneLayer = new SceneLayer({
url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/Building_Hamburg/SceneServer/layers/0",
title: "Hamburg Buildings"
});
map.add(sceneLayer);
```
3. 设置 SceneLayer 的可见性和渲染选项
```javascript
sceneLayer.visible = true; // 设置可见性
sceneLayer.renderer = {
type: "simple",
symbol: {
type: "mesh-3d",
symbolLayers: [{
type: "fill",
material: {
color: "red"
},
edges: {
type: "solid",
color: [50, 50, 50, 0.8]
}
}]
}
}; // 设置渲染选项
```
4. 监听 SceneLayer 的加载事件并执行相应操作
```javascript
sceneLayer.when(function() {
console.log("SceneLayer loaded successfully");
}).catch(function(error) {
console.log("SceneLayer failed to load:", error);
});
```
以上是 SceneLayer 的基本用法,你可以根据自己的需求进一步调整和扩展。
