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 =`
- // global remix - Del 30/10/2019
- #ifdef GL_ES
- precision highp float;
- #endif
- #extension GL_OES_standard_derivatives : enable
- vec2 resolution = vec2(1.0,1.0);
- uniform float time;
- uniform vec2 mouse;
- varying vec2 vUv;
- floatsnow(vec2 uv,float scale)
- {
- float _t = time*1.1;
- uv.x+=_t/scale;
- uv*=scale;vec2 s=floor(uv),f=fract(uv),p;float k=40.,d;
- p=.5+.35*sin(11.*fract(sin((s+p+scale)*mat2(7,3,6,5))*5.))-f;d=length(p);k=min(d,k);
- k=smoothstep(0.,k,sin(f.x+f.y)*0.003);
