Mapbox 与 Babylon.js 可视化 glsl 特效篇（二十二）
我决定不从Babylonjs 基础来讲了 直接整合mapbox与babylonjs可视化来讲
我整合一个类库 后续不断更新中
- npm i @haibalai/mapbox-babylonjs
初始化mapbox-babylonjs 类库， map 是mapbox.gl 的map 对象
- import { BabylonMapManager } from "@haibalai/mapbox-babylonjs";
- BabylonMapManager.init(map);
添加特效
- import { BabylonMapManager } from "@haibalai/mapbox-babylonjs";
- const fragmentShader = `
- uniform float iTime;
- const vec2 iResolution = vec2(1.0,1.0);
- varying vec2 vUv;
- voidmain(void) {
- vec2 p = (vUv - 0.5 ) * 2.0;
- // vec2 p = (2.0*fragCoord-iResolution.xy)/min(iResolution.y,iResolution.x);
- // background color
- vec3 bcol = vec3(1.0,0.8,0.7-0.07*p.y)*(1.0-0.25*length(p));
- // animate
- float tt = mod(iTime,1.5)/1.5;
- float ss = pow(tt,.2)*0.5 + 0.5;
- ss = 1.0 + ss*0.5*sin(tt*6.2831*3.0 + p.y*0.5)*exp(-tt*4.0);
- p *= vec2(0.5,1.5) + ss*vec2(0.5,-0.5);
- // shape
- #if 0
- p *= 0.8;
- p.y = -0.1 - p.y*1.2 + abs(p.x)*(1.0-abs(p.x));
- float r = length(p);
- float d = 0.5;
- #else
- p.y -= 0.25;
- float a = atan(p.x,p.y)/3.141593;
