      It's more about giving you a visual queue as to what the window contains as opposed to being able to read the contents comfortably. Think about the progression:
      Text -> Icon -> Pager -> Angled Window
      Each one gives more insight as to what's a particular window does than the previous incarnation. Make sense now?

      It's not supposed to make you more productive. The meaning of life, for some of us at least, is not to become more and more productive until we die. There is something about mankind, something inside of us, that wants to be entertained and amused, and this includes being in an asthetically pleasing environment (like a well decorated home, or in this case, a futuristic desktop that no one else on their block has).

        You are both cretins ;-) It is not about being productive or aestethic. It is about finding the right balance for you, like it is for everything else in life: Finding the right balance. Also, I tend to favor the aesthetic part of things when I am at home, and the productivity when I am at work.

        aesthetic is good, but it has to leave room to some productivity as well. I wouldn't live in an extremely beautiful and pleasant home if it didn't have any shelf to store my books for example.

        Extremes are bad. It's all about balance. And the point of balance is different for everyone of us.

            To me, the perfect Window manager has functions for tiling vertically and horizontally, for minimizing all windows (like Meta-M in Windows), and for minimizing and saving the minimization and then unminimizing (like Meta-D in Windows), and must have a titlebar theme that looks good though has a pixelwidth of five or less (like MicroGUI/ NanoGUI) Oh, and it has a shortcut for opening an rxvt terminal mapped to "alt-X."

            To date, the only Window managers I could get all of these things to happen in are Sawfish and TVWM.

            Knowing that one man's feature is another man's bloat, Window managers should put everything into modules and make it easy to add/remove features.

            The best way to go is to make the core contain an event manager, a titlebar manager, and an API.
            Everything else should be components that add in later, since anything could be bloat, though it should be capable of adding anything else.

            The only Window manager that I know that is that tiny but also extensible is TVWM, though extension is a real pain.

            If the window managers are extremely difficult to extend, then bloat goes in and stays in. Much better to live without it and "stifle innovation" by making it a separate program or part of an extensible manager.

      from the site:
      "Auto scale mode. The window with the focus has its normal size, the others "normal" windows are scaled (here 70%). This is done automatically. This reduce windows overlapping as the content of the scaled windows are still viewable.
      Shot-3 Surface mode. Windows are automatically rotated to simulate a non flat screen (here a 1/4 of sphere). Optionally, the window with the focus is not rotated. Note the zoomed mplayer.
      Shot-4 Peeling (or folding) window operation. "Clicking on a corner of a window of a window peels it back, revealing the window underneath it. The window springs back to its original position when the mouse button is released." (From M. Beaudoin-Lafon paper "Novel interaction techniques for overlapping windows")."

      If you only have 1 window open at a time, it would be useless. If you have multiple windows, shrinking or moving at an angle keeps them in view. Being able to zoom out and still keep it visible gives more desktop space.

      Wonder what multiple videos would look like, if any movement the window could be enlarged. You could do all kinds of interesting new things with this type of desktop, if its not staticly rendered.

      2) Writing code in a microgravity environment, you would need your windows to match your attitude relative the monitor.

      Despite the excessive dissing on the general idea, there's more than just eye candy to this. Yes, the eye candy is nice and cool, but a big part of this is making more efficient use of space in the desktop and taking advantage of our natural visual ability to process 3D information.


      Several people pointed out with the Looking Glass screenshots the other day that keeping a bunch of foreshortened (i.e. nearly perpendicular to the screen) windows open lets you actually see whats in them and visually manage multiple tasks better than you can with current overlapping 2D windows. Yes, you can do the same with a bunch of miniaturized 2D windows on the side of the screen, but it's still a good concept. The "peeling" feature demoed here with Metisse is also nice - I like the idea of bending a window aside to see what's behind it. The sphere-embedded windows uses a trick similar to the Looking Glass window foreshortening to create more available desktop space for multiple tasks by keeping a bunch of non-primary windows angled around the primary task window which faces the user directly, like a normal window, for optimal visibility.


      Obviously, you generally want the primary focus of your attention to be as easily visible as possible. This is all about making multitasking more intuitive and easier to manage. I don't think anybody is going to run out and install any of this stuff on their mother's desktop at this point, but it's great that some of this stuff will at least be ready for experimentation soon. I know that the window soup that is usually my desktop would be nice to improve on, and I've never really found any of the existing funky alternative window management technologies (like the entirely keyboard driven X WMs with no overlapping - forget what this is called) to be very satisfactory for me.


      Oh, and eye candy, combined with even very modest usability enhancements, sells stuff. Though those Matisse screenshots are about as ugly as sin thanks to the terrible window borders, color schemes and applications they chose to mix. The Looking Glass screenshots, on the other hand, were quite hot and sexy looking.

      The only problem that eating solves is nourishment, but yet people eat a variety of foods. Some foods taste better than others. Some people taste foods differently than other people, yet we only really need it for nourishment.

      Any project started by a programmer or group of programmers is to fill some need, which may only be personal. Like food, we like variety and sometimes want something different or better or the combo of the two.

    I mean I think what they're doing is cool in terms of "hey let's try this" but I don't see this as where window managers are headed. People still want fast and colorful icons and a nice file browser that's well integrated with apps. If you're unsure what I meant, compare the "save as" dialogs in mozilla and kedit.

    1. scaled windows - it's one thing to resize your windows and tile them. That's very old news. Scaled windows are another beast. Scale your firefox window everything shrinks, you don't get a bunch of "A..." "B..." tabs. Instead you get "Apples" "Boxes" etc.. in what amounts to a smaller font. Not always better or worse than resizing, but a nice new tool.

    2. Skewed windows - Yeap, I can't read em' either. What is the point? It _may_ be easier to browse multiple windows and forefront the one you want using skewed/rotated effects (instead of an alt-tab ring or taskbar).

    3. Window peeling - this is kinda nifty. Instead of minimizing, resizing or moving your current window to see what is underneath you 'peel back' part of the parent.

    Earthshattering breakthrough in UI? Nope. A reliable and consistant cut-n-paste would be of more immediate value. But as an experiment into improving the GUI it is fun stuff.

    Keep in mind that 3d desktops have the ability to increase system performance because of rendering into pixmaps instead of rendering into the framebuffer...

    Why does rendering into pixmaps possibly increase performance?

    If you're rendering into a pixmap, having something occlude it onscreen (i.e. in the framebuffer) will -not- be a destructive operation, and you won't have to repaint..

    In otherwords, sliding windows across the screen, animating some huge mouse cursor (larger than HW mouse accel would allow, for some strange and uncouth reason), or otherwise putting stuff up in front of windows would not cause them to redraw because their pixels would not be damaged by the operation.

    This is good.

    There is a negative-- You use more memory on your graphics card/AGP memory, but even this can be alleviated by switching what windows/buffers you render into offscreen pixmaps.

    One could, for instance, render all but one window into the framebuffer, save the colorbuffer and depth buffer, then render things in the 'active' window into an offscreen pixmap, and render that into the scene. This would require less memory than a full-off every-window-gets-its-own-pixmap approach, and would still likely perform better than our window managers today (only one repaint of windows is needed when you switch contexts, as opposed to one every frame with the current method)

    I'm really not trying to flame or anything, but it always seems to me that while open source geeks have great technical skill, they completely lack any sense of art.

    This window system is cool. It's cool in the same way that Aero Glass will be cool and how the Java3D desktop is cool. But what really turns me off about those screen shots is that horrible window manager. It's like whoever designed it has absolutely no sense of aesthetics.

    Here's the thing... if you want a minimalist system, then fvwm2 is great. It's not a really attractive look, but it's small and fast. But if you're going to require a lot of horsepower so that you can rotate windows in 3-space and all the other cool stuff, then it's not asking much to want a window manager with some textures and lighting and curves and some other stuff that looks halfway attractive.

    Well, some parts of this are nice. I have reservations about the actual 3D parts, but window scaling would come in handy.

    Having another X server to mediate this stuff isn't very clean though; I understand that they went that way for early development, since there isn't really anything finished that would be better, and they apparently wanted to get to the effects stuff. On the long run, however, it seems that this stuff should be done by a Compositing Manager. Of course, this also requires that the X Composite Extension [freedesktop.org] be implemented in mainstream X servers (read: X.org [x.org]).

    Back in the early 80's, color CRT's started to become available. People's reaction was remarkably similar to current reaction to 3-D desktops. Some people thought is was pretty, and that was enough. Lots of people wondered what good it was, and whether expending more than one bit per pixel was really a good use of memory. Would X become bloated? Would bit-blit still work? Some programmers who liked black and white better because they found it easier to read.

    • One important difference - displays are inherently 2D. People have been trying to cram 3D functionality onto a 2D display for a long time now; it just doesn't work all that well.
    • I think your analogy is a bit strained for a few reasons. In the 80's while monochrome monitors might have had slightly higher native resolutions in some cases, the addition of color vastly improved the ability of good app designers to direct attention quickly to where it was needed with color clues.

      Going 3D in most cases for text actually reduces readability, as most 2D fonts are carefully crafted to look good on the discrete pixels that make up a raster image. Anti-aliasing helps, but is not a panacea. I find that I do my own zooming operation manually with my head (moving it closer and farther away) as I look around my monitor at work. The idea of automatically shrinking non-focus windows 70% is kind of interesting (if the fonts still looked good at 70%), but doesn't require 3D.

      I have a large projection screen monitor at home (8 foot wide) and can drive it a Quad-XGA (2048x1536), I find it great for 3D games and Movies, but not so good for most other applications. I was puzzled by this, but I think it is because you can't change your perspective quickly by leaning in and out or moving your head.

      I suspect that 3D will one day be the norm, but only once we have monitors blasting out more pixels than we can easily differentiate across a field of view of more than 90 degrees. I'm not going to do the math, but I suspect that would be something like 6000x30000 or 18 mega pixels. Once we cross that boundary, then 3D starts to make a lot of sense, as the scaling and rotation do not unduly degrade text information even on small fonts, and starts to add information and ease organization. This assumes that moving the apps and text around is intuitive and easier, similar in ease to the way I move my head around when staring at my monitor at work today.

    Why throw a ton of people into quickly improving an emerging new technology when we can split all those people up into smaller teams to try & develop the same thing from several different angles.

    Thus rather than continually improving upon potential "killer apps" (not that I'm saying Looking Glass is such an app), we can all slowly develop slightly different versions of the same thing, all the while ensuring that cross-compatability doesn't exist.

    Oh! And don't forget the reunion party in 2 years when we all get drunk and lament the fact that products from the likes of Microsoft stole the fire that should have been ours. Even though our solution was technically superior to Microsofts.

    Ok... Maybe I do sound a bit jaded, but it sure does seem that as soon as a killer new technology or application comes on the market, we suddenly have a ton of applications being produced trying to replicate the performance of that technology, rather than either building upon the strengths of it, or developing a totally different, non-copycat alternative. Wassup with that?

    Dancing poodles are interesting, not because they dance well, but because they dance at all. These 3D desktops are interesting, but only as a sideshow. The desktop/document/filecabinet paradigm is tired not because it is inadequately modelled on out computers, but because no one wants to work that way anymore.

    X, Aqua, Windows: they're all sufficiently 3D, with stacked windows. If anything, they could use less dimensionality, and simplify the inherent complexity: window groups, accessible process data/logic/presentation tiering with pluggable dataflow, pattern copy/paste, OS-level replication and triggers, omnimedia messaging by reference, flowchart programming.

    Making a 3D "desktop" is worse than just bogging down in a 20th Century soulkilling paradigm. It's distracting us from using the 3D parallel processors to separate presentation from logic and data, to obtain all those other features which reflect the way modern people intercommunicate at work, play and everything in between. Hopefully the open source of these new arrivals will allow the best functions to be salvaged and dragged into a new paradigm created by a visionary person or group. Then these machines might start becoming less of their own problems to solve, and begin to disappear in the magic of a real solution.

    I can't believe 100+ comments and nobody mentions this.

    I think we all agree that VR interaction as presented in the early 90s was a complete crock. It is not more efficient to have to "walk" into a "room" to find stuff on your computer. And the necessary hardware at that stage was rudimentary, slow and bulky.

    Forget all that other crap. Put on your VR goggles and run a system like Metisse. Run all your existing applications in windows as normal, only now you can put them anywhere in 3D space around your workstation. Have dozens of windows open at once, all easily accessible, without desktop switching.

    Long webpages could be opened to full height, sticking up through the ceiling and down through the floor. Instead of scrolling, move the whole window so the area of interest is closest. Pick out interesting sections (images or whatever) in the distance before you've "scrolled" there.

    I can think of endless ways a 3D window manager could be used in conjunction with VR technology, even without any specialised applications. If I could seriously set one up now, I would. I'd probably still use my CRT as a second display device (after all, I might need to show something to other people).

    Realistically speaking, this isn't practical without true see-through displays. (I want to be able to see the rest of my environment behind the windows -- such as the keyboard -- and the current displays of this type, to my knowledge, use camera passthroughs which are probably a bit laggy and nauseating to use.) But I want one, as soon as the tech catches up -- assuming it hasn't already...

    And it's cool. A little slow (OK, so I ran it on top of KDE) but I think it has some cool features, the setup I really liked was: - surface like a sphere or cylinder - window auto scaling to 40% - auto flat (the window you focus on becomes flat instead of staying all distorted). That window-peeling stuff is very nice, although I don't know how useful it can be, unless it gives you enough time to bring the window in the back to the front before becoming flat again. This stuff can be really useful for having many windows on the same desktop (could be a little better than having several virtual desktops). I think this could at least be used as the foundation for an Exposé-like feature in other window managers. Of course someone is bound to say that OSS should innovate and not just imitate, but hey, Exposé is really cool, someone could add a similar feature (though not exactly the same) to KDE, GNOME or both...

    Some of the features in Looking Glass seem kinda pointless, like that 3d cd jukebox idea. The organization of windows by tilting them out of the way looks like a good way to waste screen space.

    Metisse seems to take a slightly different approach. The features outlined in the screenshots actually look like they make an effort to help users manage windows. I do agree somewhat with Steve Jobs' position that users shouldn't have to be janitors; a system that makes some useful decisions for the user seems worthwhile.

    It looks like Metisee preserves window locations when using the 'shaped' screen and scales contents down, allowing users to utilize spatial relationships and visual cues to find data.

    I also like the idea of folding over window corners to see the lower windows. Seems more useful then Alt-Tabbing. This feature is implemented from a research paper. I've seen several posts here that lament open source's propensity to copy rather than innovate. Here is a concrete counter-example of an open source project trying something new and leveraging academic research. Even if the project is a complete failure, it should be applauded for taking a risk and implementing something different.

    As an aside, I remember some comments on the original Looking Glass article that critized flipping widgets over to change settings and view properties. The new Tiger Dashboard in Mac OS X is now doing the same thing. The reviews seem positive on that score. I can't really decide what I make of that. Property sheets sometimes obscure their apps, so I guess flipping is a wash, but I think I would prefer to see the application and its properties.

    The second screen shot [insitu.lri.fr] about the "Auto Scale mode" looks like a feature that works better than Expose on OS X. The thing I don't like about Expose is having to work with function keys or desktop hot corners in order to activate it. The Auto Scale mode looks like a version of Expose that runs while you are working, without having to resort to function keys or hot spots.

    It looks like a feature in which the shrunken windows are visible around the normal size active window, without any overlapping. I presume switching between windows requires you to simply click on a shrunken window, which would resize it to normal and shrink the previously acitve one, kind of similar to Expose.

    This also eliminates the need for a Task Bar, and would also have the advantage of actively showing the windows contents, rather than just representing a window with a Task Bar button. OS X can display a minimised window's contents in the dock, but this Auto Scale mode can display minimised window contents in a larger fashion, depending upon the space available on the screen.

    I also presumed that Expose was OS X's answer to the Task Bar, because their dock didn't allow you to switch windows as efficiently as the Task Bar. This Auto Scale feature looks like something that is a combination of Expose and the Task Bar, but works better than both. I think this is a really innovative concept for window managers.

    The screenshots for Metisse suck and you can only use FVWM - what gives? It is a great demonstration of how productive Java is though.

    Looking Glass: Looks awesome
    Metisse: Looks like crap

    Looking Glass: one guy in his spare time
    Metisse: "a lot, see the source" (really one dude hacking other sources though)

    Looking Glass: very secure
    Metisse: insecure (it's in C and it's hacked up code)

    Looking Glass: easy to write plug-ins, dynamically load
    Metisse: hack fvwm in C, recompile

    There was an article a while back saying that the language doesn't matter for security because it is bad programming that is responsible. Even without looking at the source I can guarentee there's no buffer overflows, double-free's, format string exploits, etc in Looking Glass. And I would bet my life savings there's at least several in Metisse.
