Cesium 与 Babylon.js 可视化 glsl 特效篇（二十三）

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 iTime;
 uniform vec2 iResolution;
 varying vec2 vUv;
 vec3 COLOR1 = vec3(0.0, 0.0, 0.3);
 vec3 COLOR2 = vec3(0.5, 0.0, 0.0);
 float BLOCK_WIDTH = 0.01;
 voidmain(void) {
 vec2 uv = (vUv - 0.3) * 2.0 ;
 // To create the BG pattern
 vec3 final_color = vec3(1.0);
 vec3 bg_color = vec3(0.0);
 vec3 wave_color = vec3(0.0);
 float c1 = mod(uv.x, 2.0 * BLOCK_WIDTH);
 c1 = step(BLOCK_WIDTH, c1);
 float c2 = mod(uv.y, 2.0 * BLOCK_WIDTH);
 c2 = step(BLOCK_WIDTH, c2);
 bg_color = mix(uv.x * COLOR1, uv.y * COLOR2, c1 * c2);
 // To create the waves
 float wave_width = 0.01;
 uv = -1.0 + 2.0 * uv;
 uv.y += 0.1;
 for(float i = 0.0; i < 10.0; i++) {
 uv.y += (0.07 * sin(uv.x + i/7.0 + iTime ));
 wave_width = abs(1.0 / (150.0 * uv.y));
