Metisse - New Looking Glass Alternative
Interested in a 3D desktop? zoso submitted news about about a project called Metisse, writing "There is working and freely available alternative to the (soon to be released under GPL) Sun Looking Glass 3D desktop ( Slashdot story here)
If you have spare CPU/GPU cycles just go download and compile the first publicly available version of this X Desktop. Everything looks nice (screenshots here), has OpenGL support, transparency and all other whistles...."
It's also the name of a cool Irish-French musical duo

is how this is going to make me more productive. I can barely read the text when the windows are put into those weird angles.
HOW'S MY POSTING? CALL 1-800-POSTING
tell me why I would want to look at my document while it's twisted sideways?

Where are the 3D Apps? Why 3D desktop always have to be like 2D desktop, except for some 3D change..
;)
Its not a evolution..
I'll stick with the command line..
You seem to be misunderstanding it. The pixmaps are updated in real-time. There are two layers: the Xwnc layer renders the windows as pixmaps, and the FvwmAmetista displays the pixmaps using OpenGL.

Right now these folks would prefer a spare webserver and some bandwidth. :-)
I think there are other assumptions that need to be challenged prior to this sort of thing being built. Namely, that "applications" are the best way to segment functionality within an OS. This sort of system really seems to address the problem of moving between windows to access and work with different information from different applications. I think the problem of having to move between applications ought to be addressed first.
Finally, is anybody aware of any studies of this type of interface that prove me dead wrong? That prove that people are fantastically more efficient using a mechanism like this?
I'm all for whistles, don't get me wrong, but without the bells, I'm just not convinced.

3D computing environments won't be quite useful until we get a 3d input. A mouse is meant to move around a 2d desktop, not a 3d environment.
We need a 3d input device, perhaps like the ones used in Minority report? That's how I see 3d displays becoming useful.
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).
1) If you are standing to one side of your monitor, it would appear perfectly straight.
2) Writing code in a microgravity environment, you would need your windows to match your attitude relative the monitor.
3) Twisted? At least it's not doing the hokey-pokey.
4) Or *is* it?
5) If your document were Medusa, you would not want to look directly at it.
6) If you combine two sideways documents and a Clippy, you can make an airplane and fly it around your desktop.
7) 2D is teh L4M3.
8) You get more points per kill because it's harder to shoot them.
9) Extreme coding challengers are bored and want new horizons.
10) Anybody can type in a straight line.

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.
I'm running kde 3.2.2 on a p4 1.8 ghz with 512 mb of ram and it's sluggish compared to windows xp. I don't think time should be spent trying to make cool looking 3d wm's but trying to improve xfree (alright, now xorg) or kde.
Excellent idea. When can you start?
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.

"I know this, this is UNIX!"
I love it how ignorant people think that the same group of people are working on everything gui related, from browsers to video drivers.
Geezus man, this guy probably has NOTHING to do with KDE or the XFree86 project. If he wants to sit and watch pr0n all day or write a 3D window manager, it's his damn business.
It always amazes me how people can have such a gimmee mentality.
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 be implemented in mainstream X servers (read: X.org).
Only if it's an idiotic action! :)
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.
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.
...End Rant...
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?
as far as I'm concerned, what practical use does a 3D desktop environment give me? If anything, i'll get the windows so twisted that I won't be able to use them anymore.
first let me get a program that operates in complete 3D (like a 3D website that needs a browser that can display in 3D) then once windows appear as 3D boxes instead of planes, i'll use a 3D window manager.
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 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...
Go hug some trees.
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 awesomeMetisse: 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: from scratch because of Java APIs
Metisse: hacked X server, hacked FVWM, hacked vnc.
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.
There was an article recently about Java performance where most posters insisted it's still slow and jerky, but the movie of Looking Glass sure looks good to me. It's sad that people still use C/C++ to create lame hacks like this Metisse when there are such better alternatives. Can you imagine if the whole OS was written in a modern language?
Just because X is rendered with the help of OpenGL, it does not mean that the Linux GUI environment is up to MacOS standard. It is the what's inside windows that count, not how things are rendered on the screen.
OpenGL or not, the Linux GUI still looks like a hack...and the screenshots showing Emacs don't help.
The vastly different look and feel, from one app to the other, is one of the main problems, but it is never gonna go away...
