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 ratio;
 float PI = 3.1415926;
 uniform float iTime;
 // uniform vec2 iResolution = vec2(1.0,1.0);
 varying vec2 vUv;
 struct Gear
 {
 float t;
 float gearR;
 float teethH;
 float teethR;
 float teethCount;
 float diskR;
 vec3 color;
 };
 floatGearFunction(vec2 uv, Gear g)
 {
 float r = length(uv);
 float a = atan(uv.y, uv.x);
 float p = g.gearR-0.5g.teethH +
 g.teethH/(1.0+exp(g.teethRsin(g.t + g.teethCount*a)));
 float gear = r - p;
 float disk = r - g.diskR;
 return g.gearR > g.diskR ? max(-disk, gear) : max(disk, -gear);
 }
 floatGearDe(vec2 uv, Gear g)
 {
 float f = GearFunction(uv, g);
