Arcgis 与 Claygl 可视化 glsl 特效篇（三十九）

我决定不从claygl基础来讲了 直接整合arcgis与claygl可视化来讲
关于整合clagyl 有兴趣看我这篇文章 arcgis 与 claygl 引擎结合做地图可视化

我整合一个类库 后续不断更新中

npm i @haibalai/gismap4-claygl

初始化gismap4-claygl 类库， view是arcgis的sceneView对象

import { ClayglMapManager} from “@haibalai/gismap4-claygl”;
ClayglMapManager.init(view);

添加特效

import { ClayglMapManager} from “@haibalai/gismap4-claygl”;
import * as clay from “claygl”;
