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)
