Cesium 与 Babylon.js 可视化 glsl 特效篇（三十五）

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;
 vec2 iResolution = vec2(1.0,1.0);
 varying vec2 vUv;
 #define AA 1
 #define HEIGHT 12.
 vec3 _col;
 #define iTime time
 #define PI 3.14159
 #define TAU 6.28318
 vec3 spunk(vec2 uv)
 {
 vec3 col = vec3(.55,0.35,1.225);
 uv.x += sin(0.2+uv.y0.8)0.5;
 uv.x = uv.x50.0;
 float dx = fract(uv.x);
 uv.x = floor(uv.x);
 float t = iTime0.4;
 uv.y = 0.15;
 float o=sin(uv.x215.4);
 float s=cos(uv.x33.1).3 +.7;
 float trail = mix(95.0,35.0,s);
 float yv = fract(uv.y + ts + o) * trail;
 yv = 1.0/yv;
 yv = smoothstep(0.0,1.0,yv
