Cesium 与 Babylon.js 可视化 glsl 特效篇（三十四）
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;
- vec2 resolution = vec2(1.0,1.0);
- uniform float zoom;
- varying vec2 vUv;
- #define PI 3.14
- mat2 rotate3d(float angle)
- {
- return mat2(cos(angle), -sin(angle), sin(angle), cos(angle));
- }
- float f=0.005+sin(iTime);
- voidmain()
- {
- vec2 p = (vUv -0.5) * 2.0 ;
- p.x *= resolution.x / resolution.y;
- p = rotate3d((iTime * min(2.0*iTime,iTime*20.0)) * PI) * p;
- float t;
- t = 0.045 / abs(0.8 - length(p));
- t += 0.035 / abs(1.0 - length(p-vec2(0.05,0.0)));
