关键代码：
let rgbeLoader = new RGBELoader();
rgbeLoader.loadAsync("three/050.hdr").then((loader) => {
//添加球形反射映射
// texture.mapping = THREE.EquirectangularReflectionMapping;
const material = new THREE.MeshStandardMaterial({
map: loader,
});
//根据几何体和材质创建物体
const mesh = new THREE.Mesh(cubeGeometry, material);
mesh.geometry.scale(1,1,-1);
//将物体加入到场景
scene.add(mesh);
//设置场景背景
// scene.background = texture;
});
