// 添加天空盒
    addSky() {
        const loader = new THREE.TextureLoader();
        const texture = loader.load(
            new URL('@/assets/approaching_storm.jpg', import.meta.url).href,
            () => {
                texture.mapping = THREE.EquirectangularReflectionMapping;
                texture.colorSpace = THREE.SRGBColorSpace;
                this.scene.background = texture;
        });
    }

 此方法为添加360影像拍出的图像作为天空盒。如需其他方法可参照背景与天空盒 - three.js manual (threejs.org)

如果需要找360的图像可以去这=>HDRIs • Poly Haven
