I plan to create interactive virtual tours on panoramic images. I want you to create a flow on how it can be done using Three.js. Please only write 8 lines at a time. Once I'm done reading, I will ask for the next 8 lines.
 1. Start by setting up your project directory and installing Three.js using npm.
2. Create an HTML file with a div element to hold your panoramic image.
3. Using JavaScript, create a scene, camera, and renderer for your Three.js project.
4. Load the panoramic image using the TextureLoader function.
5. Create a large sphere geometry and use the panoramic image as its material.
6. Add the sphere to the scene and position the camera inside the sphere.
7. Create hotspots on the sphere to indicate areas of interest.
8. Use raycasting to detect user clicks on hotspots and trigger events.

(Continued in the next post)
1. Create a scene with a panoramic image using the Three.js loader.
2. Add a mouse cursor to the scene using the Three.js pointer object.
3. Set up an event listener to detect when the mouse enters the scene.
4. Use the mouse position to set the focus point of the panoramic image.
5. Set up a mouse wheel event listener to zoom in and out of the panoramic image.
6. Add interactive elements to the scene such as buttons and sliders.
7. Use the keyboard to move around the panoramic image.
8. Add an animation to the scene to give it a more dynamic feel.
