Cesium 与 Babylon.js 可视化 glsl 特效篇（三十六）
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 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;
