Cesium 与 Babylon.js 可视化 glsl 特效篇（二十九）
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;
- const vec2 iResolution = vec2(1.0,1.0);
- varying vec2 vUv;
- float time;
- floathash( float n )
- {
- return fract(sin(n)*43758.5453);
- }
- floatnoise( in vec2 x )
- {
- vec2 p = floor(x);
- vec2 f = fract(x);
- f = f*f*(3.0-2.0*f);
- float n = p.x + p.y*57.0;
- float res = mix(mix( hash(n+ 0.0), hash(n+ 1.0),f.x),
- mix( hash(n+ 57.0), hash(n+ 58.0),f.x),f.y);
- return res;
- }
- floatSmokeParticle(vec2 loc, vec2 pos, float size, float rnd)
- {
- loc = loc-pos;
- float d = dot(loc, loc)/size;
- if (d > 1.0) return 0.0;
- float r= time*rnd*1.85;
