Open Standards for Real-Time 3D Communication

I first heard about VRML back in 1996 from a local (Fargo, ND) web-developer who described it to me as “HTML for 3D”. While I’m sure he got this from someone who described VRML to him, the main point that came across to me was that VRML was as easy to use as HTML, and it would one day become as prevalent. Possibly, one day, a content author could place both HTML and VRML text within the same text document. Skipping a head ten years we still wait for Web3D technology to equal HTML as a means for conveying information over the web, and we still need seperate plug-ins to display our X3D content. Its not as easy as the 1996 hype first made it out to be.

Recently, however, two major HTML Browser manufactures, Opera and Mozilla, have begun working together under the banner of the WHAT Working Group (http://www.whatwg.org/) to develop 3D rendering capabilities for the <canvas> tag. The <canvas> tag was first introduced by Apple in the Safari 1.3 HTML browser for the purpose of dynamically rendering 2d vector graphics.

Essentially, the future of embed gives you the equivalent of the animated .gif option for X3D. Everything interactive you want to do in your scene has got to be in the scene already. Once its loaded, it must be treated as a complete object with no access to its internal properties. But Hey, that is OK, because the .x3d object, like the animated .gif object, can do anything it wants as long as it stays in it's container.

If it won't work cross these two browsers using the simplist way, let's try the next simplist way by leveraging Tony's Ajax3D.org tutorials to get this done. I think we can predict that if we keep it simple Ajax, we can get it to work in both IE and Ff.

Ajax3D offers a solid beginning for server-side event-driven logic combined with a client-side rich 3D GUI in X3D. What we need in addition, is a commercial library of drag and drop components for building applications. The 3D Generation is coming of working age and starting to buy. I like free plug-ins like everyone else, but the competitive-edge is in the latest and greatest. Companies beyond the Consortium members need to support the X3D formats too. X3D and SAI have to be to real-time 3D what wav files and VST are to music.

Wouldn't it be lovely if we didn't have to concern ourselves with the html? So far, it remains Not Possible to present a single html object tag that provides sufficient guidance for both Firefox and IE, for instance. The way to show active content using X3D hosted on a typical html/xhtml web browser is to use simple ecmascript to evaluate a basic browser capability check and generate a specific object element based on browser object implementation preferences and capabilities.

The hot things in 3D today seems to be anything dealing with 3D cartography, mobile, medical imaging and social networking. All of these were strongly represented at our SIGGRAPH talks. All of these areas present unique challenges and opportunities for X3D's advancement as more than an ISO standard, but as a popular real world solution to 3D communications.

Recently there has been a lot of conversation on the public mailing lists about COLLADA and X3D. As is usual with standards discussions, there is an attempt to create a "which is better" division - kind of a World Wrestling Entertainment Smackdown between COLLADA and X3D. But I think that spectacle is artificially contrived and created in part by confusion about what goals and markets X3D and COLLADA actually target.

5-10 years ago people were touting that it would only be a matter of time before everyone started building 3D web sites just like they were building HTML pages. What happened? Is it that 3D on the web failed? Or is it that many of us didn''t really understand that the Web is a much bigger and more diverse place than HTML pages? X3D, particularly in it's XML incarnation, is actually growing very very rapidly on the web. But it's not growing as HTML pages - it is growing as real XML-based applications that demand serious technical chops to develop.

The world is finally starting to pay wide-scale attention to 3D! From Google Earth, to Second Life, to 3D PDFs, to COLLADA, to scores of new uses and implementations of X3D, 3D visualization has finally reached critical mass. But while it is exciting that there are so many different technology options, how do we decide which solution to use? Is there one standard that fits all markets?

The 3D medical imaging market is over a half billion dollars and is headed for significant growth in the next 5 years, fueled by advances in imaging hardware capability, new diagnostic techniques and low cost, high performance graphics acceleration. CT virtual recontructions of the heart, virtual fly-throughs of the colon, and molecular imaging are just the start.
