Arcgis 与 Claygl 可视化 glsl 特效篇（二十八）

我决定不从claygl基础来讲了 直接整合arcgis与claygl可视化来讲
关于整合clagyl 有兴趣看我这篇文章 arcgis 与 claygl 引擎结合做地图可视化

我整合一个类库 后续不断更新中

npm i @haibalai/gismap4-claygl

初始化gismap4-claygl 类库， view是arcgis的sceneView对象

import { ClayglMapManager} from “@haibalai/gismap4-claygl”;
ClayglMapManager.init(view);

添加特效

import { ClayglMapManager} from “@haibalai/gismap4-claygl”;
 import * as clay from “claygl”;
 const fragmentShader = `
 uniform float iTime;
 const vec2 iResolution = vec2(1.0,1.0);
 varying vec2 vUv;
 float time;
 floathash( float n )
 {
 return fract(sin(n)43758.5453);
 }
 floatnoise( in vec2 x )
 {
 vec2 p = floor(x);
 vec2 f = fract(x);
 f = ff*(3.0-2.0f);
 float n = p.x + p.y57.0;
 float res = mix(mix( hash(n+ 0.0), hash(n+ 1.0),f.x),
 mix( hash(n+ 57.0), hash(n+ 58.0),f.x),f.y);
 return res;
 }
 floatSmokeParticle(vec2 loc, vec2 pos, float size, float rnd)
 {
 loc = loc-pos;
 float d = dot(loc, loc)/size;
 if (d > 1.0) return 0.0;
 float r= timernd1.85;
 float si = sin®;
 float co = cos®;
 d = noise(hash(rnd828.0)83.1+mat2(co, si, -si, co)loc.xy2./(pos.y.16)) * pow((1.-d), 3.).7;
 return d;
 }
 floatRockParticle(vec2 loc, vec2 pos, float size, float rnd)
 {
 loc = loc-pos;
 float d = dot(loc, loc)/size;
 if (d > 1.0) return 0.0;
 float r= time*1.5 * (rnd);
 float si = sin®;
