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 = `
- precision highp float;
- uniform float iTime;
- uniform vec2 mouse;
- vec2 resolution = vec2(1.0,1.0);
- varying vec2 vUv;
- floatball(vec2 p, float fx, float fy, float ax, float ay) {
- vec2 r = vec2(p.x + sin(iTime * fx) * ax, p.y + cos(iTime * fy) * ay);
- return 0.09 / length(r);
- }
- voidmain(void) {
- // vec2 uv = (vUv - 0.5) * 2.0;
- vec2 p = (vUv -0.5) * 2.0 ;
- p.x *= resolution.x / resolution.y;
- float col = 0.0;
- col += ball(p, 1.0, 2.0, 0.01, 0.02);
- col += ball(p, 1.5, 2.5, 0.02, 0.03);
- col += ball(p, 2.0, 3.0, 0.03, 0.04);
- col += ball(p, 2.5, 3.5, 0.04, 0.05);
- col += ball(p, 3.0, 4.0, 0.05, 0.06);
- col += ball(p, 4.5, 5.0, 0.06, 0.07);
- col += ball(p, 5.0, 6.0, 0.07, 0.07);
