VRML had failed, and many of the VRML-based companies hoping to bring 3D to the web had folded. The Virtual Reality Markup, or Modeling, Language, was created in 1994 to put virtual worlds on the internet. It is the 3D version of HTML, used to create web pages. The VRML failure did not, however put Web-based 3D graphics into the ashes forever. Without a standard definition of Web-3D to constrain them, new ways appeared to give web visitors real-time, 3D interactive computer graphics on the Web. These graphics could be viewed and manipulated via web 3D players (plug-ins) from within standard browsers (IE, Netscape). Web 3D players work like game engine : they put 3D-models or 3D-scenes onto visitor's screens, render the models in real time, and manage interactions. Typically, the players live on a Web 3D company's server and are accessed through browser plug-ins that must be downloaded and installed. The barriers to player usage have gone way down; today players automatically install and update. The quality you can get now with 3D-Demos is beginning to make business sense. Of course, the narrow internet pipeline means that 3D graphics have to be relatively light. "We put a limit of about 2500 polygons on our models" says Brad deGraf, founder of DotComix SanFrancisco. Web 3D companies have concentrated on finding ways to send less data through the player. For exemple, smart streaming techniques in some Web 3D players send only the data needed to create the graphics that are in the user's view; and in other players, data-compression methods are used to pack more data into smaller files (Cult3D) Data compresion is accomplished with authoring software, which can also be used to define interactions. Because this technology is proprietary and the methods are unique to each company, 3D scene created for one company's player cannot be viewed with another company's player. And because each player must be downloaded, this can be a difficulty for visitors who want to look at 3D models on website that use various players (unless plug-ins are already installed with standard browsers - as Flash is part of IE 5). "There are probably 30 companies with Web 3D players right now," says Michael Arrington, director of software research for Jon Peddie Associates - Sausalito CA. That's likely to change as content creators begin focus on a few, popular 3D plug-ins. "Our strategy is to be the de facto standard; we want to be the MP3 of 3D-Demos on the Web" says Jim Madden, president and CEO of Cult3D /Cycore USA SanMateo CA. "But none of the 30 companies has a total solution" says Arrington, "However they have real sucess in various niches such as e-commerce, entertainment, training... standards will evolve for each of these different niches (as Macromedia Director is becoming a standard for CD games). To win the competition, having unique technology won't be enough."These companies need the right partners, the right business model, the right marketing and buzz, enough funding, and they need mind share" says Wanda Meloni, an analyst with M2 research SanDiego CA, who specializes in 3D models. And then they have to show that their solution works That is, it pays to put 3D-models on website rather than or in addition to text, images and video. Content creators have become competent at designing HTML-based web pages; however, relatively few have worked with 3D tools. What's important is what 3D is being used for To make money, the Web 3D companies use one of three schemes : selling their authoring software, licencing their technology to other companies, or charging Web sites a usage fee to publish 3D-models that streams through their 3D player. All companies provide the player plug-ins free for downloading. Discreet SanFrancisco, a division of Autodesk SanRafael CA, is specialized in animation and digital video effects software. Discreet's 3DstudioMAX has become, arguably the standard 3D modeler and animation software for Web content creators - at least in term of entertainment and e-commerce, which are two markets targeted by many companies with Web 3D plug-ins. On the
entertainment side, In e-commerce, photorealistic interactive 3D-models on the Web Also targeting the e-commerce niche on the Web is Viewpoint. Viewpoint Media Player 3.0 can play back QuickTimeVR, IPIX panoranic. Sony uses Viewpoint has created Aibo, a virtual dog that develops and grows based on a user's interaction with Sony website. Cult3D claims that 10,000 product-3D-Demos can be viewed online with Cult3D player (with installed base of 6 million users), and 450 companies are using Cult3D on their websites including NEC, Boeing, Lego and Palm. Like Puse and Viewpoint, Cult3D gives away free authoring software and charges a license fee based on the number of unique visitors to a site. Cult3D imports models from 3D modelers as 3DstudioMAX, Alias-Wavefront's Maya and 3D.com's Strata3D, and is one of the few to support the Macintosh. To import more 3D models into Cult3D faster, RealViz France +SanFrancisco can convert photographs into 3D images. RichFX helps Neiman Marcus website to sell models of Manolo Blahnik shoes in a 3D environment. In development Macromedia announced it will incorporate 3D internet technology from Intel's Architecture Lab plus 3DspeedDraw, a real time renderer from NxView into Shockwave, making the popular multimedia player 3D-enabled (with installed base of 137 million users). The Intel technology allows 3D-model to have multiple resolutions, automatically increasing or decreasing the 3D quality depending on computer power. Last year Eyematic merged with Shout Interactive to target consumers with non-professional 3D Web publishing tools. Because Shout3D player works via a Java applet, there is no plug-in to download and the software is cross-platform. Eyematic's technology allows non-professionals to create personal 3D avatars of themselves from photographs. education and training market are targeted by Vcom3D Orlando Fl. Game and mapping are targeted by WildTangent Richmond WA. Although now primarily for retail games on Microsoft's Zone.com (msn Gaming Zone), one game is an e-commerce application: The Tacoma Adrenaline racing game, created for Toyota by WildTangent, the game is attracting as many players as retail games, according to Kevin Gliner, vp of product development. "It's an ad that people like to play" he says. Making a market Distribution of 3D player is vital, but ultimately the success of 3D on the web wil depend on content. 3D will be acceptable only if it adds value to the experience whether that's in commerce, entertainment, training or communication. Presentation tool for product displays For parts catalogs market, Actify Spinfire SanFrancisco put complex
models created with a wide variety of CAD tools, on the web. "In the manufacturing
space, the ability to measure a part impacts buying decisions. And service reps need to
work with accurate designs" says Spinfire mkg director, Mark Gisi. Even though
the CVAD date are compressed by as much as 90%, the company claims that measurements are
as precise as with the original data. Engineering tools for collaborative CAD Barbara Robertson, Computer Graphics World Nov 2000 RealMedia Player EKKLA Research (solutions sans fil d'imagerie 3D) optimise hardware et software pour
