Implementing a THREEjs Virtual Tours Engine with Smooth Texture Transitions

I built a THREEjs Virtual Tours Engine that employs scene.background to switch equirectangular images with a fade transition. The process fades out the THREEjs render canvas to white while the texture loader THREE.TextureLoader() loads the next image. Once the new texture is ready, the canvas fades back in to reveal the updated scene.

This project uses orbit control THREE.OrbitControls to enable looking around, and it employs an animated GIF textured on a plane geometry mesh to transition between locations. The 360 photographs were captured with a Nikon 4k camera.

I notice you've shared your Three.js virtual tour project, but I don't see a specific question about it. Based on the context available to me about Three.js scenes, I can provide some information about the scene components you're using.
Your project uses scene.background to display equirectangular images as 360° panoramas, which is a common approach for virtual tours. The Three.js Scene class serves as the container for all your 3D objects, including the camera that users control with OrbitControls to look around the panoramic environments.
If you have specific questions about:
- Improving the fade transitions
- Optimizing texture loading
- Adding fog effects using
FogorFogExp2to enhance atmosphere - Scene management techniques
- Any other Three.js scene-related functionality
Please let me know what specific information you're looking for, and I'd be happy to provide more targeted assistance based on Three.js documentation.
