Mapbox 与 Babylon.js 可视化 glsl 特效篇（四十一）

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 =`
precision highp float;
precision mediump float;
uniform float battery;
uniform float time;
vec2 resolution = vec2(1.0,1.0);
varying vec2 vUv;
voidmain(void){
vec2 uv = (vUv -0.5) * 2.0 ;
vec2 cen = vec2(0.5,0.2);
float circle = distance(uv,cen);
float outCir = step(circle,0.25);
float inCir = step(circle,.18);
float t1 = time * 3.0;
vec2 v0 = vec2(cos(t1),sin(t1));
vec2 v00 = vec2(cos(t1 - 1.57), sin(t
