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 highp float;
- #endif
- uniform float time;
- vec2 resolution = vec2(1.0,1.0);
- varying vec2 vUv;
- #define NUM_PARTICLES 50.
- #define iTime time
- #define iResolution resolution
- #define R iResolution.xy
- floatCir (vec2 uv, float r, bool blur) {
- float a = blur ? 0.01 : 0.;
- float b = blur ? 0.13 : 5./R.y;
- return smoothstep(a, b, length(uv)-r);
- }
- voidmain( void ) {
- float intensity = .2;
- vec2 fragPosition = (vUv -0.5) * 2.0 ;
- for (float i = 0.; i < NUM_PARTICLES; i++) {
- float angle = i / NUM_PARTICLES * 2.0 * 3.14159;
- float rotatedAngle = angle + time * 1.0;
- vec2 xy = vec2(cos(rotatedAngle), sin(rotatedAngle)) *
