Arcgis 与 Claygl 可视化 glsl 特效篇（二十四）-526互联

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

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

添加特效

import { ClayglMapManager} from "@haibalai/gismap4-claygl";
import * as clay from "claygl";
const fragmentShader = `
uniform float iTime;
uniform vec2 iResolution;
varying vec2 vUv;
mat2 m(float a){float c=cos(a), s=sin(a);return mat2(c,-s,s,c);}
floatmap(vec3 p){
p.xz*= m(iTime*0.4);p.xy*= m(iTime*0.3);
vec3 q = p*2.+iTime;
return length(p+vec3(sin(iTime*0.7)))*log(length(p)+1.) + sin(q.x+sin(q.z+sin(q.y)))*0.5 - 1.;
}
voidmain(void) {
vec2 p = (vUv - 0.5) * 2.0 ;
vec3 cl = vec3(0.);
float d = 2.5;
for(int i=0; i<=5; i++) {
vec3 p = vec3(0,0,5.) + normalize(vec3(p, -1.))*d;
float rz = map(p);
float f = clamp((rz - map(p+.1))*0.5, -.1, 1. );
vec3 l = vec3(0.1,0.3,.4) + vec3(5., 2.5, 3.)*f;
cl = cl*l + smoothstep(2.5, .0, rz)*.7*l;
d += min(rz, 1.);
}
gl_FragColor = vec4(cl, cl.x);
}
