Information About

Adobe Atmosphere




Adobe Atmosphere (often abbreviated '''Atmo''') is a 3D Computer Graphics creation product originally developed by Attitude Software . In November 1999 , Adobe Systems purchased the technology. Adobe released its last version of Atmosphere, version 1.0 build 216, in February 2004 , then discontinued the software in December 2004 . The product spent the majority of its lifetime in Beta Testing .


FEATURES


Atmosphere distinguished itself from pre-existing technologies like VRML and ActiveWorlds in several ways. Unlike VRML, which displayed three-dimensional "models," Atmosphere focused on explorable " Worlds " (later officially called "environments"), which were linked together by "portals," analogous to the World Wide Web 's Hyperlinks . These portals were represented as spinning squares of Red , Green , and Blue that revolved around each other and floated above the ground.

Portals were indicative of the Atmosphere team's desire to mirror the functionality of Webpage s. Although the world itself was described in the .aer (or .atmo) file, images and sounds were kept separately, usually in the GIF and WAV formats. Objects in worlds were scriptable using a modified version of JavaScript , allowing a more immersive environment, and worlds could be generated dynamically using PHP . By version 1.0, Atmosphere also boasted support for Flash animations and WMP movies.

Unlike the more centralized structure of ActiveWorlds, in which environments are primarily built within ''AlphaWorld'', Atmosphere worlds were spread throughout the Internet, usually hosted on the author's own website as .aer files. (The .aer format was later used solely for building, once the binary .atmo format was created.) As in ActiveWorlds, the user navigated an Avatar ; in later builds, an option allowed the user to see his or her own avatar. An early quirk of Atmosphere displayed users whose avatars had not yet loaded as colorful, slanted cylinders, and announced the arrival of users with a " Bug Zapper " sound.

views and multiple floating tool Window s, the Atmosphere Builder was reminiscent of both CAD software and Adobe Photoshop .]]

Whereas in ActiveWorlds it is only possible to communicate with users within a 200-meter radius, Atmosphere users could chat with all the users in the world. This was more appropriate for Atmosphere, considering the smaller sizes of most worlds. Technically, users could chat with anyone in the same YACP ''channel'', a reference to the IRC protocol (see Below ). The exception was when worlds would receive too many visitors, as was often the case at ''HomeWorld'': worlds would "clone," creating duplicate channels for the same world, which would often cause confusion for users. Some world developers wrote scripts that limited communication to users within a certain distance, for greater realism.

A built-in Havok physics engine, detailed rendering, and dynamic lighting also contributed to the realism of Atmosphere worlds.


HISTORY


Adobe Atmosphere started as 3D Anarchy by Attitude Software. It originally relied on IRC for chat functionality.

Atmosphere came as two stand-alone applications: the Builder, which was used to build online "worlds," and the Player, which allowed users to explore these worlds. (In 3D Anarchy, these components were called Editor and Chat, respectively.) In addition to these applications, Adobe provided a browser Plugin , to explore these worlds within a Web Browser , and a companion Open-source Chat Server called Adobe Community Server, which ran on an IRC-like protocol known as '''Yet Another Chat Protocol''' (YACP). During beta-testing, all components of Atmosphere were available free of charge.

In August 2002 , Adobe began to scrap the stand-alone Player, instead devoting more resources to develop the Atmosphere Plugin, which was at the time viewed as a buggy, less attractive alternative to the Player. For the most part, the Player ran only on Internet Explorer for Windows, despite frequent requests by community members to expand Atmosphere support to Mozilla -based browsers, and to Linux and Mac OS .

Adobe eventually decided to charge for the Builder, which was simply renamed Atmosphere, and continue to provide the Plugin and Server for free. As the beta-testing program ended, Adobe sent free copies of the Builder to registered beta-testers in late 2003 and early 2004 via Airborne Express and DHL .

As part of its efforts to garner commercial interest in the software, Adobe introduced support for Embed ding Atmosphere worlds into PDF documents, for viewing in Acrobat Reader . After a long period of relative silence from the developers, however, Adobe announced in December 2004 that it would not continue development of the software. According to an FAQ from Adobe:

"The decision to discontinue Atmosphere 1.0 was based on market conditions, customer feedback and research done by Adobe."


Adobe still provides 3D capabilities in its more popular Adobe Acrobat product; however, these features were developed using technology from New Zealand -based Right Hemisphere , rather than using Atmosphere.2


COMMUNITY


Atmosphere had a dedicated beta-testing community, whose members constructed many worlds and avatars, promoted the software by word of mouth, and conducted community events, such as world tours and building contests. The largest of these contests was ''Star Wars 3D'', a large-scale effort to create a comprehensive set of worlds and avatars based on the '' Star Wars '' trilogy. The creations were unveiled on July 4 , 2003 , and festivities officially continued until July 6 . Another large effort held was themed to the '' Lord Of The Rings '' trilogy.

Community members also organized and attended events such as ''World Tours'', which featured innovative worlds each week, and ''TechTalks'', a monthly event intended for world and avatar developers. To supplement the official Atmosphere product website and discussion forums, the community created a large number of resource websites, some of which are listed Below .

Beta-testers dubbed the Atmosphere developers " Zombie s," in recognition of the long hours the Adobe employees apparently spent developing the software.

Despite the decentralized structure of Atmosphere and the popularity of the world-building contests, the Atmosphere community still preferred to gather in worlds created by Adobe and its partner DigitalSpace , such as Adobe's annually-revamped ''HomeWorld'' and DigitalSpace's ''Atmospherians Community''. As the ''HomeWorld'' was the primary starting place for new users, the community found it easier to establish lively crowds there. When Adobe shut down ''HomeWorld'', along with a number of other Adobe-hosted worlds, many builders made attempts at emulating the success of ''HomeWorld'' with their own starting points, but without the constant stream of new users that ''HomeWorld'' experienced, most of these attempts failed to attract more than a small group of regulars.
