Adobe Labs has an experimental project called Project Beyond the Seen that generates 360° panoramas from 2D images. The project uses AI to convert a regular image into a 360-degree view, so you can create panoramic imagery without a lot of heavy lifting.
For a more advanced tool, Skybox AI is a next-gen tool that uses AI to create 360° panoramic worlds. It's got tools like Text-to-Skybox, Prompt Enhancer and Remix that let you fine tune visual style, weather and more. It also can export 3D mesh files, so it's a good option for content creators and game developers.
