Cesium 与 Babylon.js 可视化 glsl 特效篇（二十一）
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 iMouse;
- varying vec2 vUv;
- floatCircle(vec2 uv, vec2 pos, float r){
- float d = length(uv - pos);
- return r / d;
- }
- floatrandom(vec2 p)
- {
- return fract(sin(dot(vec2(100.,324.), p)) * 22141.);
- }
- voidmain(void) {
- // vc - voronoi coords, mc - metaballs coords
- vec2 vc = (vUv - 0.5) * 2.0;
- vec2 mc = vc ;
- vc.x *= iResolution.x/iResolution.y;
- mc.x *= iResolution.x/iResolution.y;
- // voronoi
- vc *= 9.;
- vec2 i = floor(vc);
- vec2 gv = fract(vc) - .5;
- float minDist = 1.;
- for(float y = -1.; y <= 1.; y++)
- {
- for(float x = -1.; x <= 1.; x++)
- {
- vec2 o = vec2(x,y);
- vec2 rp = vec2(random(i + o.xy), random(i + o.xy));
- vec2 p = o + sin(rp * iTime) * .5;
- float d = length(gv - p);
