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 =
- `
- #ifdef GL_ES
- precision mediump float;
- #endif
- vec2 resolution = vec2(1.0,1.0);
- varying vec2 vUv;
- #define PI 3.14159265358979323846
- uniform float time;
- voidmain(void)
- {
- float pi = atan(-1.0) * 4.0;
- vec2 uv = (vUv -0.5) * 1.0 ;
- float c = fract(abs(cos(time*1.5)));
- float r = length(uv);
- for (int i = 0; i < 3; ++i)
- {
- float b = (float(i) + 0.5 + time) * pi / 3.0;
- vec2 a = vec2(cos(b), sin(b));
- c = abs(c - smoothstep(0.0, 0.005, clamp(dot(uv, a), 0.0, 0.005)));
- }
