1. 注意事项：1在 https://account.mapbox.com/access-tokens/ 注册access_token信息

2. 按照案例即可运行
   this.scene = new THREE.Scene();
   const ioToken = ‘自己申请去，我不提供’;
   const tgeo = new ThreeGeo({
   tokenMapbox: ioToken, // <---- set your Mapbox API token here
   });

   const terrain = await tgeo.getTerrainRgb(
   [46.5763, 7.9904], // [lat, lng]
   5.0, // radius of bounding circle (km)
   12); // zoom resolution

   // const scene = new THREE.Scene();
   terrain.rotation.z = Math.PI * 0.5
   terrain.scale.x = 50
   terrain.scale.y = 50
   terrain.scale.z = 50
   terrain.position.z = -50
   this.scene.add(terrain);
