Cesium 与 Babylon.js 可视化 glsl 特效篇（十）
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 ratio;
- float PI = 3.1415926;
- uniform float iTime;
- // uniform vec2 iResolution = vec2(1.0,1.0);
- varying vec2 vUv;
- struct Gear
- {
- float t;
- float gearR;
- float teethH;
- float teethR;
- float teethCount;
- float diskR;
- vec3 color;
- };
- floatGearFunction(vec2 uv, Gear g)
- {
- float r = length(uv);
- float a = atan(uv.y, uv.x);
- float p = g.gearR-0.5*g.teethH +
- g.teethH/(1.0+exp(g.teethR*sin(g.t + g.teethCount*a)));
- float gear = r - p;
- float disk = r - g.diskR;
- return g.gearR > g.diskR ? max(-disk, gear) : max(disk, -gear);
- }
- floatGearDe(vec2 uv, Gear g)
- {
- float f = GearFunction(uv, g);
