Cesium 与 Babylon.js 可视化 glsl 特效篇（三十三）
我决定不从Babylonjs 基础来讲了 直接整合cesium与babylonjs可视化来讲
我整合一个类库 后续不断更新中
- npm i @haibalai/cesium-babylonjs
初始化cesium -babylonjs 类库， map 是cesium 的viewer对象
- import { BabylonMapManager } from "@haibalai/cesium-babylonjs";
- BabylonMapManager.init(map);
添加特效
- import { BabylonMapManager } from "@haibalai/cesium-babylonjs";
- 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);
