我决定不从Babylonjs 基础来讲了 直接整合cesium与babylonjs可视化来讲
我整合一个类库 后续不断更新中
npm i @haibalai/cesium-babylonjs
初始化cesium -babylonjs 类库， map 是cesium 的viewer对象
import { BabylonMapManager } from “@haibalai/cesium-babylonjs”;
BabylonMapManager.init(map);
添加特效
import { BabylonMapManager } from “@haibalai/cesium-babylonjs”;
const fragmentShader =
`

uniform float time;
uniform vec2 mouse;

if ( abs(p.x) > abs(p.y) * mg )
