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;
floathash(float x)
{
return fract(21654.6512 * sin(385.51 * x));
}
floathash(vec2 p)
{
return fract(21654.65155 * sin(35.51 * p.x + 45.51 * p.y));
}
floatlhash(float x, float y)
{
float h = 0.0;
for(int i = 0;i < 5;i++)
{
h += (fract(21654.65155 * float(i) * sin(35.51 * x + 45.51 * float(i) * y * (5.0 / float(i))))* 2.0 - 1.0) / 10.0;
}
return h / 5.0 + 0.02;
return (fract(21654.65155 * sin(35.51 * x + 45.51 * y))* 2.0 - 1.0) / 20.0;
}
floatnoise(vec2 p)
{
vec2 fl = floor§;
vec2 fr = fract§;
fr.x = smoothstep(0.0,1.0,fr.x);
fr.y = smoothstep(0.0,1.0,fr.y);
float a = mix(hash(fl + vec2(0.0,0.0)), hash(fl + vec2(1.0,0.0)),fr.x);
float b = mix(hash(fl + vec2(0.0,1.0)), hash(fl + vec2(1.0,1.0)),fr.x);
