Cesium 与 Babylon.js 可视化 glsl 特效篇（四十九）
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 =
- `
- #ifdef GL_ES
- precision mediump float;
- #endif
- uniform float time;
- varying vec2 surfacePosition;
- vec2 resolution = vec2(1.0,1.0);
- varying vec2 vUv;
- #define PI 3.14159265358979
- #define N 50
- voidmain( void ) {
- float size = 0.05;
- float dist = 0.100;
- float ang = 0.0;
- vec2 pos = vec2(0.0,0.0);
- vec3 color = vec3(0.2);;
- for(int i=0; i<N; i++){
- float r = 0.3;
- ang += PI / (float(N)*0.5)+(time/60.0);
