To view an IPIX, you need a stand-alone IPIX viewer or a plug-in that works within another application, such as a Web browser. The viewer allows you to move within the IPIX environment to view different parts of the image.
Interactive Pictures Corporation, which is also called IPIX, offers a variety of viewers and plug-ins for free, and sells tools to create and manipulate IPIX images. A competing format for panoramic images is QuickTime Virtual Reality (QTVR), developed by Apple Computer.
