Mapbox 与 Babylon.js 可视化 glsl 特效篇（十九）
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 iMouse;
- varying vec2 vUv;
- #define PI 3.1415926
- #define NUM 20.
- #define PALETTE vec3(.0, 1.4, 2.)+1.5
- #define COLORED
- #define MIRROR
- //#define ROTATE
- #define ROT_OFST
- #define TRIANGLE_NOISE
- //#define SHOW_TRIANGLE_NOISE_ONLY
- mat2 mm2(infloat a){float c = cos(a), s = sin(a);return mat2(c,-s,s,c);}
- floattri(infloat x){return abs(fract(x)-.5);}
- vec2 tri2(in vec2 p){return vec2(tri(p.x+tri(p.y*2.)),tri(p.y+tri(p.x*2.)));}
- mat2 m2 = mat2( 0.970, 0.242, -0.242, 0.970 );
- floattriangleNoise(in vec2 p)
- {
- float z=1.5;
- float z2=1.5;
- float rz = 0.;
- vec2 bp = p;
