Two years in the making, I finally released Pannellum 2.0, which is a near complete rewrite. The renderer was replaced with raw WebGL, and multiresolution panorama support was added, along with a fallback CSS 3D renderer. Other additions include support for JSON configuration files, hotspots, tours, compass headings, CORS, partial panoramas, and cubic panoramas. I also put together a website for the viewer, registering pannellum.org. Unfortunately, there is still a dearth of documentation—something I need to work on. The below example demonstrates the multiresolution, hotspot, compass heading, and tour functionality using panoramas of the George Peabody Library and a JSON configuration file.
