Mapbox 与 Babylon.js 可视化 glsl 特效篇（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;
floatsnoise(vec3 uv, float res)
{
const vec3 s = vec3(1e0, 1e2, 1e3);
uv = res;
vec3 uv0 = floor(mod(uv, res))s;
vec3 uv1 = floor(mod(uv+vec3(1.), res))s;
vec3 f = fract(uv); f = ff(3.0-2.0f);
vec4 v = vec4(uv0.x+uv0.y+uv0.z, uv1.x+uv0.y+uv0.z,
uv0.x+uv1.y+uv0.z, uv1.x+uv1.y+uv0.z);
vec4 r = fract(sin(v*1e-1)*1e3);
float r0 = mix(mix(r.x, r.y, f.x), mix(r.z, r.w, f.x), f.y);
r = fract(sin((v + uv1.z - uv0.z)*1e-1)*1e3);
float r1 = mix(mix(r
