Adobe Atmosphere is marketed as "Professional Web authoring for virtual 3D worlds."
Adobe® Atmosphere™ launches you into a new Web experience, where you can explore three-dimensional worlds and interact with 3D content in real time. Imagine walking down the aisles of a virtual store and inspecting merchandise before you purchase it. Or imagine taking a virtual tour of the Great Pyramid of Giza, where you explore its internal corridors and view details down to the chisel marks on the stone.
With the Atmosphere Browser and a standard 56K Internet connection, such rich sensory experiences are at the fingertips of any Web user. If you're a Web site developer, you can use Atmosphere Builder to design 3D environments that completely transform the Web experience.
Adobe Atmosphere also offers much more functionality, including "portals," communities, and even complete 3D worlds.
