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®;
