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;
- floatsnoise(vec3 uv, float res)
- {
- const vec3 s = vec3(1e0, 1e2, 1e3);
- uv *= res;
- vec3 uv0 = floor(mod(uv, res))*s;
- vec3 uv1 = floor(mod(uv+vec3(1.), res))*s;
- vec3 f = fract(uv); f = f*f*(3.0-2.0*f);
- vec4 v = vec4(uv0.x+uv0.y+uv0.z, uv1.x+uv0.y+uv0.z,
- uv0.x+uv1.y+uv0.z, uv1.x+uv1.y+uv0.z);
- vec4 r = fract(sin(v*1e-1)*1e3);
- float r0 = mix(mix(r.x, r.y, f.x), mix(r.z, r.w, f.x), f.y);
- r = fract(sin((v + uv1.z - uv0.z)*1e-1)*1e3);
- float r1 = mix(mix(r.x, r.y, f.x), mix(r.z, r.w, f.x), f.y);
