Arcgis 与 Claygl 可视化 glsl 特效篇（十三）

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;
 uniform vec2 iResolution;
 varying vec2 vUv;
 voidmain(void) {
 vec2 uv = (vUv - 0.5) * 2.0;
 float t = iTime * .1 + ((.25 + .05 * sin(iTime * .1))/(length(uv.xy) + .07)) * 2.2;
 float si = sin(t);
 float co = cos(t);
 mat2 ma = mat2(co, si, -si, co);
 float v1, v2, v3;
 v1 = v2 = v3 = 0.0;
 float s = 0.0;
 for (int i = 0; i < 90; i++)
 {
 vec3 p = s * vec3(uv, 0.0);
 p.xy *= ma;
 p += vec3(.22, .3, s - 1.5 - sin(iTime * .13) * .1);
 for (int i = 0; i < 8; i++) p = abs§ / dot(p,p) - 0.659;
 v1 += dot(p,p) * .0015 * (1.8 + sin(length(uv.xy * 13.0) + .5 - iTime * .2));
