Mapbox 与 Babylon.js 可视化 glsl 特效篇（十三）
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;
- uniform vec2 iResolution;
- varying vec2 vUv;
- voidmain(void) {
- vec2 uv = (vUv - 0.5) * 2.0;
- float t = iTime * .1 + ((.25 + .05 * sin(iTime * .1))/(length(uv.xy) + .07)) * 2.2;
- float si = sin(t);
- float co = cos(t);
- mat2 ma = mat2(co, si, -si, co);
- float v1, v2, v3;
- v1 = v2 = v3 = 0.0;
- float s = 0.0;
- for (int i = 0; i < 90; i++)
- {
- vec3 p = s * vec3(uv, 0.0);
- p.xy *= ma;
- p += vec3(.22, .3, s - 1.5 - sin(iTime * .13) * .1);
- for (int i = 0; i < 8; i++) p = abs(p) / dot(p,p) - 0.659;
- v1 += dot(p,p) * .0015 * (1.8 + sin(length(uv.xy * 13.0) + .5 - iTime * .2));
- v2 += dot(p,p) * .0013 * (1.5 + sin(length(uv.xy * 14.5) + 1.2 - iTime * .3));
- v3 += length(p.xy*10.) * .0003;
- s += .035;
- }
