Review Of 3D Web Browsers 207

shelflife points to this very intersting article on the 3D Web browsers in Scientific American. He writes that of the 3D systems mentioned, "A Swiss company, Geonova (, seems to demonstrate best that the idea of a geography-based Web is feasible with today's PCs. Engineers there created two impressively detailed models of Switzerland--one of the entire nation with 25-meter resolution and another of two central cantons at 50-centimeter resolution. .. Text and iconic labels hovered quite legibly above towns, lakes, companies and tourist attractions; clicking on the labels opened associated Web pages. What other 3D browsers are there -- VRML plugins have been around a while -- yet they do not seem to be successful. Why is that?"

    Web-based communication is largely interpreted, as opposed to compiled. Are there any successful examples of high-performance interpreted 3D out there?
    • Well, it doesn't _HAVE_ to be interpreted. One reason FLASH runs so well (considering all the real-time vector that it has to do) is because it's compiled. Solutions like VRML will never work (IMHO) because of the fact that they're interpreted. (Yes, I know some of you think it's this huge hog, but my PII350 runs all but the lamest FLASH at full speed).

    yuck, the reason why they don't work are because they're slow and don't benifit any. Even most 'regular' people don't want to surf the net by clicking through an interface that looks like a town. Even if it does look nice, the fun wears off after running around in your own little virtual town when you notice that it takes twice as long to find information.

      well maybe so but the thing that would be good about having the ability to run around a little town like that would be getting to know the place.

      if I had the option to run through the streets of a city, and get to know where the places to go are located physically I would like it. Then when I go upto the city for a night out - I would know where most of the businesses are, and would have more options as to what to do on a night - especially if I had never been to that city before.

      but I would still want the traditional style of browsing... and be able to "teleport" to the front of a business in the 3d environ.

      I think that it will have larger implecations as well - people would correlate brick-and-mortar with cyberspace a bit better, as you would see where a company is (or how a city is) without having to be there.

      so - in conclusion I would love to have the opportunity to travel through virtually - and what would be interesting is to run through the streets and see all the other people on that street and be able to talk to them. just like a MMORPG.

      Ignoring the low-level implementation details (i.e. specification language, size, performance) which affect user experience in obvious ways, there much more basic issues when it comes to 3D as a user interface.

      Lets be sure we're asking the right questions. The most important question is what task is this 3D 'technology' supposed to support.

      There are three common types of interaction with system data:

      1) Visualization - Seeing the data in an organized fashion
      2) Manipulation - Changing the data in some way
      3) Navigation - Getting from one piece of data to another
      Using 3D often aids in visualization. The two main reasons to use 3D here are when: 1) there's a 3D spatial relationship between the data (molecules) or 2) an additional dimension is useful to see a pattern. Remember that 2D is a subset of 3D and having the 3rd dimension does allow one to convey more information. Perhaps the biggest 'problem' with 3D visualization is occlusion. But if you're using 3D correctly, then the reason you're using 3D is BECAUSE of the information occlusion conveys. If occlusion is bad thing for a particular visualization, then a 2D view will likely be better.

      Manipulating 3D objects is often informative because you can look at the dataset from different sides. Defining the view of 3D objects is very natural for people (like when we turn a skull around in our hands). Defining which slice of the data, using a search or coordinate criteria is often harder. So 3D is often good for manipulation.

      There are some very good and pretty bad things about 3D when the tasks are to visualize and manipulate data. But the nightmare comes when one attempts to navigate data. There's a reason we like TV and movies: we don't have to physically move to get the information we're interested in. And this is where 3D apps fail in supporting users' tasks. They usually force people to physically fly through the data to get to a related, or even totally unrelated, piece of information. The alternative is to 'teleport' people to the next bit of interesting information. However, as anyone who's fallen asleep in one place and woken up in another can attest to, teleportation is an extremely disorienting experience. So this is the fatal flaw of 3D displays: flying through the data is bad, but teleporting is bad.


      So I think 3D can be useful in supporting visualization and manipulation tasks. But it is incredibly bad for navigating through data. Most 3D web projects emphasize navigation, and this is where they fail. Applications using 3D can succeed if they concentrate on what they do best, visualization and, to a lesser extent, manipulation of data. Navigation tasks should be left to the 2D world.

    even the article mentions that one of the main reasons that VRML is not in wide use is b/c of the "getting lost" factor. People just aren't accustomed to the way that VRML represents the page. It was also noted in the page that text and VRML don't mix well together.

    Apparently that's why this new fangled browser is better for 3D viewing.

    Why aren't VRML plugins used more?

    1. It's slow.
    2. No real or perceived value-add from using it. Why should I switch to a 3D filesystem browser, for example, when what I have works just fine?

    Make it faster and give us a good reason to use it, and it might get more widespread use.
    • I've seen added value. The lab I work in does some modelling of protein movements. We can use multigifs or MPEGs, but this limits the viewer to the angles we incorporate. With VRML, you can view the protein from any angle. This is something that is of interest to people in the field- I don't think standard molecular graphics packages support this type of application.

      Unfortunately changing VRML standards have broken all our files, and we do not intend to replace it. All of our content is created automatically on a Linux server, ruling out pretty much any alternative (and many of our viewers will use non-Windows platforms). For a good idea what VRML can be used for, though, look at the Protein Data Bank [] website. Try '1tim' as the search key- click on the 'view structure' link. They've done a fabulous job with this.
    • I use a 3d file system browser (fsv) and I find the different view leads to insights.

      using 2d & 3d space to represent sizes of directories & files helps you see what's going on at a glance without having to drill down all your directories etc.

  • I'm not too impressed with anything I've seen from VRML, but Adobe's Atmoshpere was a bit of an eye opener. Check it out yourself at Adobe's Site [] ... free to play with while it's in beta. I haven't personally developed for this yet, but I hear it's quite intuitive. As a bonus, you have site-specific chat. Now if they will just add site-specific-VoIP I will start taking a more active interest, but for now I think all of this 3d Browser stuff is a bit academic as noone has found any particualarly good use for this stuff yet (at least nothing that the mainstream surfer is going to clamour for).

    • Excuse me, but screw Adobe. Those litigating idiots don't deserve two minutes of your attention or admiration for any product of theirs.

    The question in the article was: VRML plugins have been around a while -- yet they do not seem to be successful. Why is that?

    This isn't a flame, but the answer is simply that nobody likes VRML. People think that things are successful because of some other force than people like something. This can be true in rare cases (huge marketing campaigns like Nike's can change what people want), but ultimately, if something isn't successful, then it is because people don't want it.

    The real question is: why don't people like VRML? Well, load it up yourself and view 3D worlds. Now play Quake. The VRML experience is unsatisfying, but Quake is fun.

    Here are some basic reasons why VRML fails to stimulate people:

    • Navigation sucks. The controls were built for people who wanted to model 3D objects from the outside, they weren't built for people who wanted to navigate the intireors of dungeons. Few people wanted to look at the 3D objects, most people want to fly through objects.
    • VRML worlds sucked. Because of (or causing) the navigation problems, most VRML were objects you attempted to manipulate rather than 3D worls you could fly through.
    • VRML didn't grok "cyberspace". Go to old VRML design documents and read the description of how they define "cyberspace", then read William Gibson's defition (or any cyberpunk definition). The VRML group was trying to model the real 3D world and objects, trying to make the PC model reality. People don't want this -- they want the computer to do stuff that you can't do in the real world. Doing real world stuff is easier in the real world -- VRML brought nothing new that the real world didn't have to offer. (This is why Quake is fun: it isn't the real world -- I love the low-grave levels :-)
    • Poor leadership. Read Mark Piesce's old writings and contrast with Linus/ESR's writings. Piesce is a petulant child compared to the maturity of Linus/ESR/Cox/etc. Emotional ranting is popular in forums like Slashdot, but leaders who behave that way hurt their projects.

    The real answer is that 3D has taken over the world and become the driving force behind computers (e.g. 3D cards in computers have more gates than CPUs). The 3D market has expanded hugely fast. There are those that figured out how to catch the wave (John Carmack @ Id) and those that failed to grok what was going on (Mark Piesce w/ VRML). One of these days we'll see some interesting 3D technology added to browsers; it won't look like VRML, it might look like Quake/Doom or Flight Simulator, or it might be something completely different.

    • Mr. Carmack has the luxury of re-inventing his technology every year or two.

      Quake I is very different from Doom. Which is somewhat different than Quake II, and very different from Quake III (the 3D technology, I mean; the gameplay is pretty much the same).

      Doom/Quake/etc is fun because Mr. Carmacks colleagues spent a lot of time creating spiffy worlds, specifically tuned to run well using what was available at a specific snapshot in the evolution of 3D graphics technology on the PC.

      So, lets say we took your advice and went back in time and codified DOOM as international standard ISO/IEC 14772-1 (aka VRML).

      Instant success, right? We'd see DOOM worlds all over the web, and lots and lots of 3D content springing up all over, because we all know that DOOM is such a fantastic virtual reality technology, and virtual reality is such a killer application...

      VRML didn't live up to expectations because the technology is lousy. You don't see more 3D stuff on the web for a bunch of reasons:

      • It is really, really hard to create 3D stuff. Much harder than creating mainly-text web pages.
      • What's the business model? Nobody has figured out how to make money with new web technologies. Microsoft controls the browser market, so Microsoft gets to decide what new browser technologies will succeed or fail. Their 3D browser effort (ActiveVRML) was even harder to create content for than more conventional technologies, and was rejected by the content creators.
      • The killer applications for 3D graphics are games (for consumers) and CAD/CAM/Architecture (for business). All of these applications get along perfectly fine with proprietary graphics formats and packages that don't really need a 3D web.
      Eventually, WildTangent will get snarfed up by Microsoft, and somebody will figure out what the killer app for 3D graphics on the web is... but I'm not holding my breath.

      PS: It's Mark Pesce, not Piesce.

      As someone a little bit closer to this issue (check webpage) this is why I think VRML failed.

      1. VRML-97 is not a superset of VRML-1. There are features in VRML-1 that don't convert easily to VRML-97 so people who started with VRML-1 had to re-do a lot of stuff by hand. That discouraged a lot of the early movers.

      2. The VRML-97 specification specified too many things that didn't need to be specified (like text layout, which looks crappy in VRML anyway) and initially failed to specify some things very well. There was some question about what scripting should be used at first, later Java and ECMAScript worked their way in but that leads me to...

      3. It duplicated things that could be done with other things. In particular, you can do a lot of 3d with Java, and if you are going to use Java to script your VRML world anyway you might as well just do everything in Java which leads me to...

      4. Crappy installed base. Really weak VRML browser shipped with IE and Netscape died before its decision could have made any impact.

      5. Somewhat different computing paradigm. The VRML file contains "sensors" which trigger events that are processed by scripts. In other words, the data drives the code instead of the code driving the data. Is it a file format? A programming language? What is it? I'll tell you, introducing a different way of computing is fine, but they didn't pitch it that way, which tells me that it was more of an accident. It's always a bad sign when different ways of doing things get introduced by accident.

      6. Bloated syntax. I know I'll catch it from some people for this, but I stand by it. Why was the proposal for VRML-97 called VRML-2? I'll tell you: because it has twice as many brackets and braces as VRML-1, and it doesn't really make things any easier to read.

      7. Performance, performance, performance. A few months ago someone on comp.lang.vrml posted something that looked like a simple Quake level. It ran at 1 FPS on my box in a tiny little window. The same box runs Quake full screen at least 24 FPS, probably more but I can't tell and I don't care because Quake looks fine. The VRML performance problem is intractable too, because it doesn't have any standard way to do BSP or any of the other tricks that games do.

      There are probably other reasons too; that's just the top of my list. Oh well, I had a lot of fun with it in the early days, and I learned a lot coding for it but it is DEAD, DEAD, DEAD. I use my VRML program mostly to create animated GIFs and for photo-shop like effects (layering translucent PNGs and taking screen shots is cool) and I keep the web page up because I hate to kill stuff. I harbor no delusions. VRML will never see mass appeal. It seems to have carved out a niche in some government and academic circles, but there is no excitement there, no profit, and not much life.

      • Somewhat different computing paradigm. The VRML file contains "sensors" which trigger events that are processed by scripts. In other words, the data drives the code instead of the code driving the data.

        It's the same paradigm HTML and Doom use. An HTML file contains "links" which trigger events that are processed by scripts. A WAD file contains "lines" which trigger events that are processed by scripts.

    • "Grok" (Score:2, Interesting)

      by danarch ( 176547 )
      OK, we're going to review the misuse of the word 'grok.'
      "Grok" is not a real word. It comes from Heinlein's sci-fi book "Stranger in a Strange Land" where, conveniently, it was never really defined (because it was a "martian" word). It has commonly been defined as "getting it".

      Unfortunately, "getting it" isn't very well-defined either. Most people seem to define "getting it" or "grokking it" as "agreeing with me." For instance:

      VRML didn't grok "cyberspace"

      VRML didn't agree with my idea of "cyberspace"

      So although the "Why not VRML" post is pretty intelligent, use of the word "grok" by the post's author and a number of other 'geeks' is not. Rather, 'grok' has become merely a euphamistic way to cover the arrogance of the person who is using the word.

      • You don't grok "grok". To grok is to have
        intimate existential knowledge. When you grok
        something, you can reason about it unconsciously.
        We don't use "grok" to cover arrogance. We
        use it to *express* our arrogance and our contempt
        for the ignorant.
      • > "Grok" is not a real word.

        What is your definition of a real word then? It looks like a word to me (an honest-to-goodness real one at that). Or is it both real and a word, but just not a "real word"?

    • Piesce is a petulant child compared to the maturity of Linus/

      Dang. He must be a really interesting subject ; )

    • I don't find Quake fun. I find it cramps my hands and arms, and gives me vertigo. Same with all first-person shooters. Plus I find it boring after about 15 minutes.

      A 3D world would require some way of getting past this barrier. One of the main problems with all 3D interfaces I have seen (including games) is the sheer amount of fine motor control required for very long periods of time.

      Instead, new input methods will be required before 3D interfaces can become a truly integral part of the net. I don't know what these methods will be, but I bet the initial ones will be based off eye movement (there are already knowledgebase systems in use in some places based on eye movement - for example, for mechanics who have the data on a HUD and use eye movement for moving pages, leaving both hands free).

      Now, Arcanum [] - that's fun! Over 120 hours so far, and I've just started it for a third time (I haven't even finished once yet - I keep going "Wow! I wonder what it would be like to play that part of the game as a <insert gender><insert race ><insert character stereotype>).

      • I would humbly suggest that since Quake and its ilk are hugely popular, the problems you have with it are not fundamental problems with "a 3d world"

        Oh, and Quake requires fine motor control largely because it's an arcade game - that's the whole point! You'd obviously want something a bit different for a mass-market browser...

    Computer screens are generally 2D, without even depth information. When we talk about "3D graphics", what it means is that we get a 2D image that transforms like the image of a 3D object when we interact with it (mouse, trackball, etc.). That is, 3D graphics is simply a particular way of showing and hiding information in response to user input. So, we need to evaluate it relative to other ways of interacting with data on the screen.

    I think in practice it has turned out that mechanisms like a folding tree and a tabbed window are more effective and easier to use for interacting with the kinds of data we deal with. Our current 2D interfaces require less user interaction and intervention and display more useful and related information than a system that is constrained by trying to conform to the rules of 3D objects. The closest to 3D we have come in user interfaces is zoomable UIs, but even there the jury is still out whether that is actually useful in practice.

  • A Swiss company, Geonova (, seems to demonstrate best that the idea of a geography-based Web is feasible with today's PCs.
    I would guess that the feasibility owes much more to Switzerland's tradition in cartography than to "today's PCs". Geonova credits the Swiss Federal Office of Topography, which maintains a map of the whole country at 1:25,000 scale -- Alps and all. I don't think there is anything quite like it in the entire world.

    (I once saw a beautiful map of Mount McKinley; looking in the corner, it was actually done by the same Office.)

    • I just got done playing around with the Swiss thing...I was impressed by the idea but hated the execution. Probably more a problem with my box than the program.
    • Don't count the USGS - the Fifteen minuit series of USGS are amazing when you consider the vast size of the US. The USGS and NASA have been working together to make them even better, with satelite topography measurements and textures, the new maps promise to be almost life-like.
    • Definitly agree. I've spent a considerable amount of time trying to locate map data for Canada. Very little map data is available in Canada for free. (In any sense of the word). That data which is available for free cannot be redistributed unmodified. (as they want it to be retrieved from the original source... whatever).

      And, the cost of full topographical maps for Canada at the highest resolution (1:50,000) is horrendous. Only some maps are even available at scales of 1:25,000. Very limited.

    What is it? You can't ask a geek to make you a stylish personal home on the web. Its just not feasable because they spent their lives reclusively, with clutter all over the room and with clean elegance on the paper products they make. Sure there is an elite few who can make WAD files already, but they cannot easily pass this knowledge on to the masses.

    Speaking of WADs, there is the difficulty in scripting events in VRML. You need a plug-in for a static language that doesn't even offer realistic doors or interaction with monsters. Where's the fun in a 10 meg download that doesn't even offer you a gun or sword or knife? VRML came out about the same time as games which for the first time offered Deathmatch mode, so it was sadly feature-poor for its size.

    If they could re-make VRML as a familiar XML-style language with some support for java and javascript, then all you would need is a good Frontpage equivalent and free interior decorating or painting courses on the web.

  • VRML remains limited by the fact there is no reliable complete set of tools available. A developer cannot author, debug and present VRML across a complete set of standards-compliant applications (authoring system, graphics accelerators/drivers, browser).

    I've always been very intrigued by VRML, and I tried to work with it on several occasions, but it just flat doesn't work, because there is always some major technological problem with either the authoring system or the browser.

    • The Cosmo Worlds suite from SGI - you can easily knock up virtual rooms/districts/worlds in minutes with the same ease as creating HTML pages with FrontPage or similar. And it definitely has a useful place - for example:

      A 3d model of an engine for mech school - click on a part and info flashes up, followed by sequence for removing/fitting the part, maybe with a virtual tutor offering advice.

      You wouldn't use it for document browsing, but that isn't what it was designed to do. It really is a piece of cake to edit manually though.

      The thing that astonishes me is people complaining of long download times - you can create detailed areas in a staggeringly small size if you are sensible about your image and texture maps. For really high res stuff, yes you will need more bandwidth, but that is always the case.
  • I can recall just a few years a go handling a tech support call for a vrml editor product (for vrml 1.0) This poor gal was doing a fancy vrml front door as the main entry for the university library, complete with books, tables, etc with links, and walk-about navigation. At the time I spoke with her, she was editing on a winbox, and uploading to a unix server, and was running into problems because of the case-sensitivity of Unix vs Windows. Typical stuff.

    She wanted this to be the main interface for the site, even for dialups. This was a time that 14.4 was still somewhat common, although they were dropping out.

    She had no problems making it run quickly over the LAN, of course, to her hot top of the line box, but had lost sight of the fact of dialup speeds. Her file was 1 meg, and growing. When I informed her of the typical 14.4 speed (14.4 = roughly 100k/minute under the best conditions) she flipped. This would be ten minutes to load on a 14.4 modem. Even with a 56k modem, that would be 2.5 minutes to load.

    Then you load the next page.

    Yes, I know of pages with 1 meg java script files.

    I think this is part of the two different design philosophies. One is to design for everyone, the most users possible. The other is to design for the power users, for the elite, the people who have the hottest software with the hottest hardware, etc.

    The widest adoption requires the moving away from designing for hi end. but them you get the old arguement that if everyone has it, it is obsolete.

    It's not just the web. Why do people still watch 2D movies and read 2D books? Why are so many top seller computer games 2D (SimCity, Civilization, Roller Coaster Tycoon)?

    Your eyes view the world in 2D (plus depth), not full 3D. Monitors are 2D. Trying to stuff a 3D world through a 2D pipe means you lose data. For example, unless you're a hyperdimensional being, you can't see what's behind something without rearranging the data. It's "cool" but it's also a pain at times. If there's no good need/benefit for 3D, then using 3D is often worse than the 2D version. Most everything I do on the web doesn't benefit from 3D. I'd rather get the 2D version.

          • How the hell have you have you lived as long as you have if you can't see in 3D?

            Perhaps you are unclear what it would mean to percieve something in 3d. This means that you would see the entirety of whatever you were looking at. You could see all sides of a cube at once, for instance.

            Getting back to the original thread, 3d browsers are displayed on a 2d surface. How does that work again?

            • This means that you would see the entirety of whatever you were looking at.

              No it doesn't. Perceiving something in 3D means I perceive it in 3 dimensions, not from 3 dimensions. I perceive a width, a height and a depth. Count them : 3.

        • No, not 3d; 2 and a half, perhaps. If i saw in 3d, i'd be able to see the back of something at the same time as the front.

          Ehh? WTF? I think that'd be more akin to x-ray vision...or disconnected eyeballs.

          3D translates to 3 Dimensional. The dimension in question are:

          1. Length
          2. Width
          3. Depth
          If you see 1D, you'd only see lines. 2D would be able to give you shapes, but no idea how deep the shape was. 3D gives you all of it. Check out Flatland [] for help...which you obviously need.

        • So, if I'm a 2d creature and theres a line in my way to one direction I can't see really see 2d? What if I'm looking in an unobstructed direction? I think what you mean if we don't see 4d. As a 3d creature I can look at a line on a piece of paper and see around the obstruction that might cause problems to a 2d creature because I can see from the extra dimension.
      • Technically s/he's right - we don't see the world in full 3D - full 3D would require some organ or whatever to actually sense depth, instead of percieve it - like being psychic and KNOWING how far away something is, and what is behind what, instead of relying on percieved depth (which is wildly innaccurate).

        Our judging of depth can be totally off sometimes. If we saw in true 3D, we wouldn't have that problem.

        • My judging of colour is off sometimes (because of the lighting, say) does that mean I don't have truecolour vision?
          My perception of width is off sometimes (optical illusion).
          My perception of height is off sometimes (e.g. more optical illusions).

          Damn ... I'm blind.

          I don't KNOW how wide something is, I don't KNOW how tall something is and I don't KNOW how something smells or tastes or feels or sounds.

          I have organs which sense depth - they're called my eyes and my brain. They've worked for me and other creatures for millions of years.

          • I have organs which sense depth - they're called my eyes and my brain.

            Good for you. I have organs which are supposed to do that, but they're broken, so I have little depth perception.

            However, your posession of that trait which I do not have does not mean you can see in 3D, it merely means you are aware of 3D - you can judge depth.

            Perhaps my distinction is needlessly metaphysical or philosophical, but the distinction is there for those who choose to see it (pun intended, derogation not).

        • Wildly inaccurate?

          If we didn't perceive depth very well indeed, we wouldn't even be able to catch a ball thrown to us.

          The idea that possessing another 'organ' would somehow add a new dimension to the world we sense is a little off base.

          Dolphins, and bats for example, use a echo-location techniques to perceive depth, with enough accuracy to catch a fish or flying insect without any visual cues whatsoever. Our ears are just not as sensitive as theirs.

          Our sense of touch is 3D in the extreme. We can feel the shape of an object, front, back and on all sides, but the nerve cells in our fingers are fundamentally no different than the nerve cells in our ear canals, its just the way we interpret the data they send, based on what we subconsciously understand about the relationship of those nerves to the rest of our world.

          We don't 'know' anything at all. We only perceive what our senses tell us. You don't 'know' if something is blue or green, you can only infer it's colour from the way it looks to you.

          If someone shines a red spotlight on a matte white object, and you look at it, you see a red object.

          If we saw in 'True Colour' we would always know what colour an object was, even in the total absence of light. This is fallacious, of course, since the concept of colour depends totally on the existence of light.

          Just as colour, the concept of 'depth' only exists because we have the means to sense it. You could surely improve or augment the way we sense depth, but would that change the way we perceive it?

  • 1) Designing for the masses. Let's assume that everyone wants to have VMRL content, and that it has been sucessfully publicized and standardized just like Flash has grown into a Internet-wide phenomenon. Even then, you have the issue of file sizes. Like it or not, the majority of the United States runs on dialup. The demonstration world didn't take long to load, but it didn't have much in the way of detailed textures either. Also, I could see my CPU usage flying up which means that one simple world puts a lot of stress as is. Imagine what happens if people try to open multiple browser windows. The combination of bandwidth and system requirements are hard to find. Face it, most /.ers don't use 233-Mhz systems like I know many of my friends do.

    2) Number one is an ideal world that will never make it for the following reasons: content.

    For the geographical view of Switzerland, I don't find much that I couldn't find on a map. The 3-d certainly adds a nice perspective, but little detail.

    I myself visited Switzerland this previous summer, and this world lacks many of the things I wish to see in an overview. My browser couldn't show me the beautiful clouds embracing Mount Pilatus, nor the grass rippling in the wind, nor the diehard runners sprinting up the mountain. These things aren't seen despite the 30 meter accuracy.

    Also, if you go into a town with a browser, you don't get what you would normally see. VMRL worlds are hard to create, even more so accurately. Pictures (including those cool panoramic 360's) capture the feeling more accurately. Also, it would be pointless to look through shops and such because the user would get lost.

    Which leads to my final point: Assuming tourists like these 3-d worlds, what about websites such as Slashdot and CNET Would talking people at newsstands give you the news to read? Would bullet points point out where the news occured? How would these be updated every day, or even every hour? Nothing is practical, and the Internet is about information. There is nothing special if the experience is only a recreation of the real world- nothing can ever match that. The Internet is about arranging all the information in a new fashion that makes more sense that what you get away from the computer.

  • Just because something can be 3D doesn't mean it should be. This applies quite a bit to desktops and browsers.

    For a lot of things a 3D interface is just too cubersome and slows you down. Why 'fly' through a modelled tunnel to follow a link in 10 seconds rather than just click some text on a web page in 1/10th of a second?

    Sure, there's a place for online 3D virtual community chat -- MMORPGs proved this, as just sitting around chatting is what they do best (most don't really have much of a game there other than kill monster, get xp, kill other monster that looks slightly different, repeat forever). But trying to integrate the whole browser (or desktop) experience into 3D is insane.

    Some things just work better in 2D, just like some things just work better with a CLI, just like some things work better with dedicated devices rather than general purpose computers...

    • What Neal Stephenson proposed in Snow Crash was that when you wanted to do actual computer work, you would enter your 3D office, say hello to your butler, and sit down at your virtual computer.

      You don't have to actually replace your CLI or file-managing programs, just include them into the new paradigm.

      Besides, who's to say that by the time these full-fledged 3D worlds are popular, that we won't have easier and more powerful ways of moving files around? I imagine that when we do, and the new tools tend to get in the way of some particular task, that they will allow us to somehow go back to the old way of doing things, just in case. Rather like how Mac OS X provides a pretty interface for all its new features, but still allows you to launch a bash shell if you need to fix something by hand.

      There is a place for 3D on the desktop- use of the illusion of depth produced by overlapping windows, only more so. I wrote up an idea piece on that, linked above, a while ago.

      Interestingly enough, MacOSX has every single bit of technical underpinning necessary to do this, in its Display PDF layer. The window-minimizing animation literally takes a full window and not only shrinks it but distorts it oddly. It would be nothing to scale windows under OSX. I'm not sure if it'd be just as easy to fade them toward a background haze color, but it's certainly eye-opening to consider. Basically, almost a year ago I was envisioning this way of using a third dimension on xterms alone, because those are already resizable in many term programs. I thought it would be impossibly tough to do that with full-on GUI apps, but OSX already does more than that- it just does not currently furnish any method for zooming specific windows forward or back in space.

      Makes me wonder if it'll be possible to come up with 'hacks' on OSX's Finder and add this behavior...

  • The web is organized by TOPICs (that is, web pages tend to be devoted to one sort of information)...and while that does include geography, things that can be organized that way are only a tiny fraction of what's out there.

    Text-based directories for local areas are easy to find, don't open up as much possibility of putting things in the wrong place, if stuff like this 3D thing were generated automagically. They're probably easier to search, too.

    The reason this won't succeed, and none will for a long time, is that they aren't especially useful, cause more problems than they solve (what problem is this supposed to solve again?) and require people to go get extra software.

    If we're going to see 3D web browsing in the near future, I'm betting it will be through Flash, as that is software that DOES do something relatively useful (if you like watching cartoons) and is already widely distributed.

  • Utilising 3D (Score:2, Interesting)

    by OzJuggler ( 174316 )
    This was alluded to in "Flawed Metaphor" by Greyfox above, but wasn't quite spelled out.

    The reason why 3D web browsers have not taken off is because 3D adds absolutely no value whatsoever to the activity of web browsing. To answer why, let's consider the broader question of: Why isn't interactive 3D everywhere? (ie- not just browsers)

    The answer is that a spatial representation adds value only when you have spatial relationships that you can load with meaning. The meaning is part of the browsing task at hand, which means that the spatial relationships must be set-up case-by-case for each type of task that someone wants to do. One of the few situations that don't require special setup are where the task is no more than real spatial navigation - like an action game or a CFD stream function.

    If you change the axes of the coordinate system from (Right,Up,Back) to (Manufacturer,Price,Item) then you now have some spatial relationships that are loaded with meaning ("higher" means "more expensive"). But you have a "space" that is no longer intuitively navigable. This is not to say that it is difficult to get around in, but that it is diffuclt to know where you are. When you find something that looks interesting, some careful thought is needed to figure out what it is that you've found in the source data. A trivial example, to be sure, but the problem becomes worse the more complicated the dataset is. (And you'd think that's where you'd need 3D the most.)

    Web sites are organised by topic and if you can organise all the topics of human knowledge using only 3 spatial axes and still keep it navigable, then you've achieved what no-one else knows how to do. That is why 3D web browsing has not taken off. (There is an arbitrary relationship between physical server location and topics stored on it.)

    As an aside, UI is a big issue too because it is easier for your brain to make sense of the space around it when you can physically turn your head to see everything around you. Another reason why a little monitor window in front of you is not going to blow anybody away. (Q3A excepted)

  • The main problem I see with the adoption of VRML or any 3D navigation system is: a keyboard and mouse do not translate well to a 3D world. Perhaps when voice recognition really gets here, that would go away -- "Computer, show me my office. Bring up that document over in that filing cabinet. Thanks." And, maybe that webcam on top of your monitor watches your eye movements and analyzes facial expression. I know these technologies are being developed, but they aren't here in terms of consumer quality. I do not believe we will be able to leave the flat page user interfaces until we quit using flat page human interfaces.
  • As far as I can tell, VRML was trying to be both Inventor and HTML. This was before XML got big, with people routinely using that sort of format for non-text. Inventor was a pain to actually view, and it influenced too many 3D viewers; VRML was watered down from Inventor, as well.

    There's now a good example of a XML-based graphics format which is at least usable, and which will probably gain substantial browser support (even if it doesn't become popular to actually use for a while). A vector graphics format, as well, is a good basis for a 3D format, because the user will be able to change the size of objects by getting closer or farther away. Extending SVG into 3 dimensions shouldn't be too difficult; it would require 3D primitives, of course, and people would have to figure out a useful user interface, but the first is relatively trivial and the second is a universal problem.
  • various research firms and government research organizations (yes, there are people who get paid taxpayer dollars to play around with search engines and 3d engines and stuff) have been trying to come up with an effective method of visualizing information (e.g. text, filesystems, etc) in 3d for many years.

    in my opinion, these browsers are neat as a novelty, but beyond that they aren't that useful. if browser people (mozilla team, opera team, konqueror people, microsoft, etc etc etc) worked on improving the user experience in existing products, we'd be doing just fine. having better information to display in the first place would help, too.

    here []'s a link that should give you a good overview of information visualization that the government is sponsoring. this [] should help, too.
  • Why do I like other people think that VRML and the likes won't take off?

    Not just because you interact with the computer using 2D, but 99% of the time, the media you will be reciving is 2D. E.G. text images, video, and music well, music dosn't realy fit, but you know what I mean).

    So from end user, to the data, it usaly goes like this:

    3D (real world) > 2D (computer) > 2D (the data).

    A 3d browser seems to do this:

    3D > 2D > 3D > 2D

    SO at the moment, there isn't much point. It's kinda like an extra convertion one has to go though to get the info.
    If the data at the end was 3D, then probably, a 3D browser could offer advantages.
    Not matter how hard I try. I just can think of a 2D > 3D system or concept as an interface for 2D data that would be better than a 2D interface.
    Any advantage to a 3D interface is lost cause the first interface (the computer) is 2D.

    Sorry if this gets in twice, server probs...

    That's easy to answer: do you want to spend 99% of your time travelling from link to link by 'walking' to portals and gateways? It's tedious having to wait till your avatar reaches a place. With a 2D browser, you click on a link and you're done. You want to get from place to place as fast as possible, that's why people spend lots of money to upgrade to something like ADSL.
  • The reason 3D web interfaces haven't taken off is because web content isn't suited for a 3D presentation.

    Consider Slashdot as an example. The content here is text. Adding 3D support to Slashdot wouldn't add anything except complexity. Going beyond Slashdot, as I think about the web pages I frequent, I don't think a 3D experience would make my browsing any more satisfactory.. in fact, I'd be more worried about more sites turning into 3D versions of a bad flash-enabled site. (We've all been there.. do you click the spinning circle or the pulsating triangle to get to the next page? [] -- the link was down when I checked, but I assume it will be back up soon.. )

    So, while I agree with everyone else about it being harder to make 3D sites, and that there's no good, modern language standard for doing 3D web work, I think the real reason is simply that the content on the web (most, not all) just isn't suited for 3D. --XaXXon

  • All of this talk about 3D worlds being slow... I just want good heads up gear to become affordable. I would spent $300+ for a good head display if it meant virtual immersion. I believe it to be great when schools - like psu invest in virtual projects. We can already see the future of VR, it will be based on technology that allows images to be overlayed onto your cornia and allow you to see the world around you while surfing the web... - the post that I'm referencing should be in the /. achives.

    I'm looking forward to VR-Web based pages expecially with widespead highspeed internet access and faster systems. What is really needed is a refining of the code.

    Just because you can, doesn't mean you should. So we now have super faster computers and graphic cards that can render 1024x768 at 60fps with 32bit colours, so what? It maybe good for gaming and some very specialised research and visualisation applications, but it is no good for general web browsing.

    Why? What does browsing mean? Reading (and maybe typing) text, and maybe some images here and there. So what does a 3D environment bring you in this case? Nothing. Reading an article in 3D is pointless; most people will rather stick with the good old "flat text".

    The reason Virtual Reality did not catch on for web browsing is that it is not bring anything new. At least not anything people think are useful outside of some very specialised cases. For example 3D maps cool! 3D /.? No thanks.

    We are still waiting for a killer (non-game) app in 3D. In the mean time, the idea of 3D browser is probably only of interest to academics researchers.
  • Greets!

    The reason that 3D isn't popular or practical - paper. Our current metaphor for information derives from Xerox Parc, a PAPER company. A faithful emulation of an office desk is NOT the best way to represent the complex infoverse we live in.

    And the current web is not the best way to represent it either. Go back to hypertextual research before the web - look at Guide, look at Microcosm, before the brain damage of HTML and Mosaic set in.

    Even better, go and look at Xanadu and ZigZag - representing information and the relationships between individual pieces of it is a complex task, perhaps made harder by our current metaphors. See ANYTHING by Ted Nelson, such as his technical briefing at the latest Hypertext conference.Read Vannevar Bush's "As we may think"

    I would argue that we don't need 3D browsers, but MULTIDIMENSIONAL infoviewers, that can let us define the relationships and properties that we are interested at any moment, AND LET US CHANGE THEM easily and intuitively - I still remember the only good part of Johnny Mnemonic - zooming around cyberspace - also, to a lesser degree Lawnmower Man.

    This is the way forward, and we need to learn from the games industry - Look at Homeworld, Q3D, even Elite - these are the kind of intuitive navigational and representational metaphors we ned to adopt to allow people to create, browse, populate and interact with their information.

    Let us be imaginative, and move forwards to a representation of information as something we can use, rather than something we write down.

  • Have you all - gone - completely - insane?
    VRML rules the Universe, and I will explain why.

    There are comments that VRML is slower than specialised game engines. Well, duh. It's a general solution, they are specific solutions. There are many things that you can do in VRML that are not possible in game engines. For example, arbitrarily large worlds. Every object being active and scriptable. In the Quake engine, it's not possible to make a door rotate on its hinge. Quake only allows for sliding doors. In VRML, of course, any object can do anything. In Quake, the largest space you can make is the size of a dance hall. In VRML, you can make a space as big as the solar system, and zoom in to a grain of sand. If you've ever tried to use a game engine, you'll know; they're great within their constraints. But those constraints are severe.

    VRML is the only general, extensible solution for VR. And it happens to be an open standard, controlled by a consortium with Open Source as a core part of its platform. It's come a long way since 1997. It's integrated into MPEG4 - go to The MPEG4 spec page [] and do a search for "VRML". It's been extended [] with NURBS, geospatial capabilities, and more. It's fully scriptable with Java, ECMAScript, and whatever else you want to plug into the open source.

    There are comments here that what we need is and XML language for Web3D. OK, fine, you got it. VRML has an XML encoding; it's called X3D []. The old encoding still works too.

    It's out there now, being used in real applications to actually do stuff with VR beyond running around in a maze shooting blocky 256-colour monsters. Not that there's anything wrong with that.

    If you want to know what's actually going on now, the best source for general Web3D info is Sandy Ressler's site [].

    If you want cool tools for VRML, go to the new kings of Web3D - ParallelGraphics []. They have authoring tools for Windows, and a browser for Mac and Windows. Unfortunately they are WinTel-centric, so no Linux, and no Mac authoring. Shout at them until they come around. Nicely, of course.

    If you want a visual VRML authoring tool for Windows, go to Spazz3D [], the most useful tool to ever have such a stupid name.

    But this is Slashdot, so here's the dirt: for the Free Software/Open Source angle, go to OpenVRML []. They have a browser for all major platforms, and if you don't like it, you can fix it yourself.
  • Why does no one use VRML? Because virtually no one can use VRML. Not for anything interesting or useful anyway. Ever looked at a VRML file with any significant detail to it? They are huge. Far too large to comfortably send around the web, even with a broadband connection. Even when network speed isn't a consideration, it still is too bloated to do anything useful with that can't be done much better with proprietary (and better designed) 3D model formats.

    In my job we use various 3D formats daily. Various CAD system (ProE, CATIA, AutoCAD, etc) native formats, IGES, STEP, STL, and yes VRML. We do work with virtual reality technologies, 3d modelling and simulation. The only use we have ever found for VRML is as a vendor neutral format for exporting tesselated images of CAD data between a few selected pieces of software. And even then we have to be careful how big the VRML we use is. 3D Studio Max (one of the more well known apps we use) will choke on a VRML bigger than 75-100 Meg. And this is on a Dual Proc 800Mhz P3 with 2Gig of RAM! You can generate a VRML that size with one automotive assembly with a decent amount of detail to it. (a single front axle module for instance) Forget building a world, you'll have trouble building more than a few simple objects with VRML.

    If we cannot use VRML for anything useful beyond simple format translation, what chance is it ever going to have to be used for something more clever? VRML is useless because it is too big and it is too slow. Simple as that. If the format sucked less, the tools would come to take advantage of it. But right now, there is no point because VRML isn't useful for anything and even with computer speed increases isn't going to be for some time to come.

    If you want to see a more useful 3D tesselated format look at .JT (from EAI []) Granted, it's proprietary and not without some other problems, but it is much "lighter" than VRML ever dreamed of being while still looking quite good. It's getting used for PDM (Product Data Management) systems in the business world which require a relatively light weight, CAD vendor neutral, tesselated 3D model. This market opportunity was created in part because VRML was too bloated to be useful. The opportunity is still there, but VRML in it's current form just isn't the answer.
  • 1) VRML2: unimplementable.
    The spec contains 3 scripting langages. There are 3 different mechanisms for animation. Everyone implemented part of it, so all VRML2 browsers were mutually incompatible, more or less, which defeated the reason to have a spec in the first place.
    Blame who you like.

    2) 3D content takes, literally, 2500 times longer to make than 2D content.
    A business wanting to put merchandise online has to do 1 week of work per model.
    A good commercial photographer can take 500 merchandise photographs a day.
    Is 3D 2500 times more compelling than 2D? (No.)

    3) It exists in a tricky place, half file format and half scripting language.
    If you're not using motion, why not use the existing Java viewers for OBJ's?
    If you're using animation, and 3d-ness isn't mission-critical, why not Flash, which is more standardized and faster?
    If the point is a walkthorough, why not a sequence of pictures?
    If you're trying to make a game, why use a plugin at all?

    Then, the reasons others noted:
    4) It's slow.
    5) It's harder to navigate.
    6) Everything looks crappy.
    7) Mom doesn't get it.
    8) You weren't allowed to sell the plugin.

  • Well, ActiveWorlds [] is a 3D chat environment that allows user building, has hundreds of worlds, and allows any object to link to a web page that appears in the web pane of the Active Worlds browser. It's always free for "tourists" as well.
