Implement smooth rotation animation around the Y-axis, handle window resizing to maintain proper proportions, and use antialiasing for smoother edges. Explanation: Scene Setup : Initializes the scene, camera, and renderer with antialiasing. Sphere Geometry : Creates a high-detail sphere geometry (64 segments). Texture : Loads a placeholder texture using THREE.TextureLoader. Material &amp; Mesh : Applies the texture to the sphere material and creates a mesh for the globe. Lighting : Adds ambient and directional lights to enhance the scene\u2019s realism. Animation : Continuously rotates the globe around its Y-axis.
