Mapbox 与 Babylon.js 可视化 glsl 特效篇（十六）
我决定不从Babylonjs 基础来讲了 直接整合mapbox与babylonjs可视化来讲
我整合一个类库 后续不断更新中
- npm i @haibalai/mapbox-babylonjs
初始化mapbox-babylonjs 类库， map 是mapbox.gl 的map 对象
- import { BabylonMapManager } from "@haibalai/mapbox-babylonjs";
- BabylonMapManager.init(map);
添加特效
- import { BabylonMapManager } from "@haibalai/mapbox-babylonjs";
- const fragmentShader = `
- precision highp float;
- uniform float iTime;
- const vec2 iResolution = vec2(1.0,1.0);
- varying vec2 vUv;
- vec3 rY(vec3 p, float a) {
- vec3 q = p;
- float c = cos(a);
- float s = sin(a);
- q.x = c * p.x + s * p.z;
- q.z = -s * p.x + c * p.z;
- return q;
- }
- // returns a pair of values for the distances along the ray at which there are sphere intersections, or 0 if none
- vec2 sphereIntersectionDistances(vec3 rayOrigin, vec3 rayDirection, vec3 sphereOrigin, float sphereRadius) {
