Pannellum is a lightweight, free, and open source panorama viewer for the web. Built using HTML5, CSS3, JavaScript, and WebGL, it is plug-in free. It can be deployed easily as a single file, just 18kB gzipped, and then embedded into pages as an <iframe>. A configuration utility is included to generate the required code for embedding.

1. Upload build/pannellum.htm and a full equirectangular panorama to a web server.
2. Use the included configuration tool (configuration.htm).
   • Pannellum Location is the address of pannellum.htm and can be either a full or relative path (relative to the page containing the <iframe>).
   • Panorama URL is the address of the panorama image file and can be either a full or relative path (relative to pannellum.htm).
   • Basic Information is optional. If provided, it is displayed in the bottom left corner.
   • Embed Size is the dimensions of the <iframe>.
   • Include Pannellum Logo includes the Pannellum logo in the upper right corner with a link to the project's website.
   • Auto Load loads the panorama when the page is loaded. If left unchecked, the user must click to load the panorama.
   • Selecting a Creative Commons License inserts a banner for the appropriate license next to the author's name.
   • Generate creates the embed code that can then be copied wherever desired.
3. Insert the generated <iframe> code into a page.

Examples using both the minified version and the version in the src directory are included in the examples directory.
