Arcgis 与 Claygl 可视化 glsl 特效篇（二十六）

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;
 #define PASS_COUNT 1
 vec4 iMouse = vec4(.0, 0, 0.2, 0);
 float fBrightness = 2.5;
 // Number of angular segments
 float fSteps = 121.0;
 float fParticleSize = 0.015;
 float fParticleLength = 0.5 / 60.0;
 // Min and Max star position radius. Min must be present to prevent stars too near camera
 float fMinDist = 0.8;
 float fMaxDist = 5.0;
 float fRepeatMin = 1.0;
 float fRepeatMax = 2.0;
 // fog density
 float fDepthFade = 0.8;
 floatRandom(float x)
