Converting RSS Feeds To a Dynamic 3D Scene In 120 Lines of Code 73

descubes writes "Tao Presentations is a 3D presentation tool based on a 3D dynamic document description language. This makes it very easy for developers to create their own 3D shows, illustrate talks in an innovative way, even build small interactive 3D applications. An example included in the latest release grabs RSS feeds from a variety of sources (including Slashdot) and turns them into a 3D scene, all in real-time and in about 120 lines of code. It fetches the pictures directly from the web site and maps them on 3D shapes. And this is only a starting point. Tao Presentations can display 3D objects, drive the majority of 3D displays (including glasses-free 3D displays from Alioscopy, Philips or Tridelity), use GLSL shaders for advanced effects, and much more. Tao Presentations is free (as in beer), and the document description language is based on the free (as in speech) XL programming language."

    but the concept is flawed in that it borders on the ridiculous. What is wrong with just reading the news in a list format? Do we need to see it rendered in 3D?

    I'm getting a strong, familiar VRML-era stench about this hype.

    So the founder and president [of] Taodyne [linkedin.com] submits a "story" extolling the virtues of Taodyne's latest program/thingie and this actually makes it onto Slashdot? Am I really expecting too much of Slashdot by thinking that this shouldn't happen? I mean the entire summary is blatantly written like an advert -- perhaps you could say the guy isn't trying to deceive anyone since it's obvious to anyone looking (eg. me) what's going on, but is that really a good direction to go in? Is even the barest of journalistic integrity a lost cause on this site?

    3D RSS feed sounds like it'll be the greatest thing since six-speaker stereo surround sound for the morse code coming out ham radios.

    Is this a blast from the past post from 1998?

    I admit I skimmed the Slashdot summary and thought it was compressing 3D information into Twitter-sized bites, similar to the Twitter music notation from a while back. But then I click on the links and see RSS FEEDS IN THREE DEES! Not even really in 3D, just with perspective.

    I'm not even going to dig up any of my "Oh, just stop with trying to display text in 3D" rants because everyone has to know by now, right? Everyone but these guys. (Hint: Do a search for VRML.)

    And what's with the "120 lines of code" crap? I could probably do the same thing in 5 lines of Processing, or a whole lot more of ASM. But this is a stupid thing that should never have been done. And not "stupid as in awesome" like launching flaming pianos with a trebuchet or "stupid as in a challenge" like getting a toaster to play Oregon Trail, but stupid as in pointless with no redeeming value.

    So as much as Slashdotters love to bash on people for not pulling the subtle points from the fine article, don't bother with this one. It was a mistake to have made it to the front page, on top o the much greater mistake of actually doing it in the first place.

    But 3D is the new 2D.

    I'm just waiting for some advancements in augmented reality, so that I can see the world around me in 3D! /sarcasm

    All sarcasm aside, 3D is not the new 2D, 3D is the new color. Black and white didn't go away, you can still use it to great effect [wikipedia.org]. But most digital content today is in color, just because we can. It looks more natural, it allows effects that you can't do in black and white.

    When you print a PDF document on a black and white printer, you expect it to look right. What's the equivalent for 3D today? Taodyne's value proposition is to make it ridiculously easy to create portable, dynamic 3D documents that will show at their best on Mac, PCs or Linux, on 2D, active 3D, passive 3D, 3D DLP projectors, 3D polarized projectors, multiscopic glasses-free 3D displays, 2D+Z, you name it.

    Sure, glasses-free 3D displays today are expensive and have limited resolution. But when Adobe launched Postscript, laser printers were prohibitively expensive, and only black and white. Today, you can practically get a color laser printer with a Happy Meal. I'm willing to bet that in 5 years, glasses-free 3D panels with resolutions of 4K or more will be commonplace. Google glasses will be the new iPhone. And you'll want to be able to create cool interactive, real-time 3D contents for these devices.

    It's time to learn how to do that now.
