3Dwm Updates 94

Posted by CmdrTaco from the way-ahead-of-its-time dept.
Robert Karlsson writes "3Dwm, the Three-dimensional window manager, an open source project at Chalmers Medialab, has just released a new, extensive release of 3Dwm, release 0.2.2 - VNC support, 3D scene graph, big texture splitting, client connection, framework, 3D materials support, testsuite added." miles away from a real desktop, but a great testbed for those ideas that are way ahead of their time.

  • AFAIK, the quake engine is very streamlined for 3d. If you were to use it as a windowing environment you could really strip it down by removing all the "game" options. The requirements for it are no longer considered high IMO.

    What I find strange is that Win 95 will run fine on a 486, but in my experience X chokes with insufficent ram. X itself is bloated, and building a WM on top of that adds to the problem. Quakes footprint is not ALL that bad, and again, you would have to modify the code for your specific purpose anyhow.

    I would love to get Carmacks opinion on this.

    The critique of the idea of a 3D windowmanager doesn't take into account it was built for a computing environment that ISN'T a desktop (the Cube) and secondly, there may very well be some applications of this we aren't yet aware of.

    I agree that burying Linux, typically the darling OS of the "why do I need a GUI when I can just grep -v -x | sed -qvf | tar -qt32pir2 : smeek -frfk > kibble.rpm ?????" set, in a 3D window manager seems weird: a total waste of CPU cycles, a criminal waste of memory, and an exponentially bad version of Microsoft Bob (eye candy that actually got in the way).

    But who knows? Maybe someone will come up with a way of visualising and representing data that'll only make sense this way.

    Time mechanics data? Physics data? Who knows?

    Just because I can't think of a reason for this yet doesn't mean one exists.
  • Yes, the program that she was using was a real program available for real unix systems--you can download it from SGI's web-site [sgi.com].
  • Actually, that app actually exists for SGI boxen!
  • They mean VNC support at the viewer side. So there is a cool 3D VNC viewer.
  • The horrible part is that this is how you actually DO picture a 4d space =).
  • yes, but without neat cool things to do there would be no reason to make the computers more stable and more fast would there?

    We wouldnt have to worry about using anything but those "totally adequate" 386's ehh?

  • Big deal, almost every window managing system ever made has incorporated the dimension of time. Though some implementations are spottier than others. For instance, the dimension of time seemed to crash and freeze quite often on my old windows box, though the other two dimensions seemed mostly unaffected.
  • I did some work using EMG signals to operate as a system controller. It gets to the point after calibration (which takes many many minutes) that you can control the signals with slight twitches instead of full motion. I think that haptics/gloves are more or less stupid unless it's a system that is designed to interpret natural movement and not a programmed controlling (Move your hand 4" up, then 2" right then 2" left and wiggle your thumb to right click). With EMG reads you can twitch.. slight muscle movements that are barely perceptible that become like second nature. That was the goal, my term working on this we never got a "functional" interface.. the mouse just got real jittery but it was a starting point.

    Don't get me wrong, I'd rather this existed than not, but wtf, how is this "way ahead of its time"!?!?!?

    If the only thing we can vary in our user interfaces is how many dimensions they display, its going to be a long time before we make any inroads into dealing with large amounts of data using arbitrarily generated paradigms that minimize the energy input required to acquire a particular piece of information.

    DATA--that is, what computers deal with--DOES NOT require a user interface mapped to the tangible nature of our reality.

    People seem obsessed with the question, "Where is it??? How is it arranged?? How is it layed out???" while the question "WHAT is it??" seems to elude them.

    Sorry if this post seems angry, but this isn't ahead of its time at all. Our interfaces and computers are BEHIND the times. (assuming objective time... yeah, we're both wrong I guess)

    Just my $.02, and yes, I am working on my own interface, but I am only 1 person, so it's going to be awhile.

  • A 3D WM itself might be somewhat of a nuisance (as is the case with 3Dwm), but adding 3D support directly into the WM would be useful. Using hardware to do anti-aliasing and alpha blending and so forth would certainly take a good amount of load off the system, and would be much faster then trying to do things at the software level. *cough* imlib2 *cough*.
  • No, no, no, wait. A three D window for visualisation of APPLICATION data is one thing. An entire WORKSTATION GUI that's 3D is another.

    The Star Destroyer could be rendered in 2D GUI but in an application window in 3D... right? It's interesting. I'm curious as to why the GUI needs to be 3D.
  • I have heard of a generator that makes random quake levels on the fly. I would love to find it again. I have an idea for a mod/game that could really make use of that technology.

    You could I suppose use flexible design in the way you used the brushes to create the level. You are correct though. The BSP design is fast when the level is already VIS'ed. Good point.
  • Note to moderators: check the posting time before moderating something as redundant. Also mine was my own project done on an apple ][c *with* stereo-scoping.
  • I would much rather have a windowing system that used what hardware I had to its full extent instead of trying to perform the same tasks in software. You might not like purchasing 3d hardware, but do you really prefer going out and spending unholy amounts of money on a new processor just so all the stuff your 3d card can do faster in hardware, can be mimicked in software, and run more responsively? If stuff was done properly from the beginning there wouldn't be as many problems. Naturally, if you want to use a 3d window manager you should have a 3d card. Or if you want to use a 2d window manager that uses 3d for some stuff then you would want your hardware to work properly with it. That of course reduces portability, but then again, some loss of portability is pretty essential.
  • My fondest wish is for a window manager that could nest windows rather than using the "virtual desktop" approach. Sort of like the Xnest X server, but lighter weight. Instead of switching to a different portion of a desktop that won't fit on the screen, you'd make a new (blank) window. An application started in that window would create all of its subwindows in the same window, so, e.g., the whole batch could be iconified and moved around as a group. Actually, I don't know enough about the X protocol to even tell if this is possible, but I can always dream. If anyone is thinking about writing X window manager #1734...

    "An x86 UNIX clone? Who needs that? What's the point if we have BSD already? And its not like x86 will ever be fast enough to run UNIX or anything! Why bother?" -Microsoft Weenie circa 1991.

Even if an idea isn't immediatly useful in raising your Q3 fps or running your JAVA project faster, it might still help in the future.

  • http://www.xspace.net/hotsauce/ Very cool stuff - what ever happened to it?
  • Just thought I'd point out that one of the main limiting factors of 3Dwm, Berlin, and similar projects becoming more than just toys is that the hardware support just isn't there. (Yes it is, if you're running under X, but that's kind of defeating the purpose, now, isn't it..?) We need a lower-level hardware acceleration protocol. DRI is nice and all, but it's X-only. Unless people start pulling X and it's drivers apart, the ball's never going to get rolling, and we're going to end up with a lot of projects that started off great, but never really went anywhere because normal everyday users couldn't use 'em.

    Several attempts have been made already to rectify this, but it doesn't look like there's been anything major really accomplished. DRI is still where all of the manpower goes, even though projects like GGI/KGI exist.

    Hopefully, someone will come out with a standard soon, and we can eliminate this kind of waste of effort. (Well, it's not likely, but we can hope, right..?)

    Preferably, such a spec would allow for:
    - kernel-level drivers that just pass along commands
    - a library where all of the actual code exists, to keep the junk out of the kernel.

    Actually, this is what KGI and GGI are.. but you can read about the XFree86 peoples' reasons for not going with their way of doing things for yourself. ... Well, I'm guessing you can. I still haven't found one, myself.

    (Incidentally, can anyone think of any reasons why this sort of thing ISN'T a good idea..?? I still haven't figured out myself why the XFree86 people are so hesitant to split X like this. Granted, it's an extra pipeline, but then again, that's pretty much what DRI is, too. And considering the added safety of not having a root application playing with kernel registers..)

  • It's funny that someone would think it wasteful to have 3D hardware supporting a WM, while at the same time others buy card after card to keep up with the requirements of various games.

    This is something that actually could serve a more general, practical purpose than a 3d game engine: 3D visualization of workspace data. This, in my opinion, is a better justification for a hardware purchase than Q3.

  • I could tab-switch between the objects on my desk, and they would float 2 feet above it in front of me one at a time...

    Seriously, though, this is a good point. If we're going to have a new sort of WM with new dimensions of navigation, then we should ideally have new input devices along with it. The mouse/trackball/whatever is already really inadequate in 2D space (to me)...

    I seem to remember some people having gotten a Nintendo Power Glove connected and working with a PC as an input device, though that might not be the best idea unless you could still type, and preferably de/equip it quickly and easily. I remember trying the Power Glove when it first came out, and it wasn't exactly the easiest thing to use (although the argument could be made that neither is a mouse unless you're used to it, which is the same argument I use about Windows vs $OS)

  • If I remember correctly, (and its been awhile since i read it) David Brin's Earth had computers with a voice activated interface similar to what you're describing... subvocal twitches in the larynx allowed the system to pick up intentions to speak and act on those, rather than waiting for the actual sounds (which could also annoy the hell out of one's coworkers. )Interesting how fiction and life aren't so very far apart anymore.

    And as far as X compatibility is concerned, that's already there. There's support, already, for getting a GGI context, from which you can run XGGI on top of it. (XGGI is an X server that runs on a GGI context.) The other method, integration of X into GGI, is something I have no clue as to what's being done.

    I seem to remember some people having gotten a Nintendo Power Glove connected and working with a PC as an input device
    The first example I remember of that was Randy Pausch's group, then at UVa, in a paper called "Virtual Reality on $10 a day," in the UIST conference. It was a cute (and effective) demonstration of how researchers were pursuing expensive toys and not actually addressing the issues. Rather than a half a mil in SGI and one-off things, Randy put together a complete, head-tracked, head-mounted, glove-input (using the Nintendo glove), 3D virtual environment, for less than $10000, in 1994. The most expensive component was the magnetic tracker for about $6000. It was monoscopic, black-and-white, and wireframe, but it did 30 HHz, using SPHIGS (the simplified educational version of PHIGS used by Foley, van Dam, Feiner, Hughes).

    Unfortunately, glove interfaces (even with a more expensive and more accurate DataGlove) have two problems: fatigue and lack of haptics.

    Re fatigue, how long can you mouse around on the desk for? (hint - how long can you play quake at one sitting?) Now try swinging your arm, unsupported, in the air for that amount of time - that's called calisthenics.

    Re haptics, a great deal of control comes from kinesthetic feedback (why you can touch your finger tips on opposite hands together with your eyes closed). When using something like a mouse, the inability to move in certain directions gives you a great deal of information. A mouse is relatively crude at this, but a pressure-sensitive tablet is better and an actual paintbrush is better still. Now pick up a virtual paintbrush (hint - you can't feel it in your fingers) and try to paint with it (hint - you can't tell when it touches the canvas). Researchers have tried substituting sound (a noise when you run into something), and "ghosting" to show where the virtual object actually is (because of physical constraints) and where you put it (i.e., straight through the canvas).

    This has, in part, I think, led to the recent research popularity of augmented reality and "virtual desktops".

If i could have a 3d view of 6 different programming sessions with a real time representation of runtime results i would. it doesn't matter how much hardware i throw at my current system, i just can't do this today. same for designers, engineers, etc. this would mean a real productivity boost.

    which brings me to my point... with the current pointer/icon/double-click/window interface, there isn't much to gain on the productivity side even if you throw in 5 years of moore's law. we're stuck. it's the same thing that happened when the GUI first came along, everyone said it was a waste of resources, but now that we have the hardware we're glad they worked on it nonetheless.

    Take a look at this screenshot [3dwm.org]. It looks to me like the desk and the screen are being generated by two separate programs, through 3dwm. And it's apparently network-transparent.

    What's really new about this seems to be the display of several 3-d programs in the same space, not the notion of a three-dimensional desktop.

    You did see Jurassic park, didn't you? You may remember the little twerp who sat down at a system and proceeded to zoom her way about the system in true Max Headroom 3D style.

    I look forward to the day when we replace /etc/passwd with a VRML file, MD5 sums with collision hulls, and the 31337 h4x0r 0wnz j00 only because of his superior dexterity.

    Mark my words - all this Quake playing you do today - this practice of button reflex and mouse coordination - this is going to pay off in SPADES once we enter the world of - 3D SECURITY!

    Where did you go to school? Simple math here

    For instance, with every mouse movement you have to calculate the new coordinates in a 3 space trialog, instead
    of the old Cartesian method.

    Even a first year calculus student knows this is BS. Moving to 3 space dosn't cause you to change from cartesian coordianates. No if for example you base your coordinates on rotational movement then you might have a point about doing something but even then it's not a function of a larger store of video ram but a faster processor.

    It's from Jurassic Park. The girl sits down at a console with a fake 3d window manager and says "This is unix! I know this!"

    Actually, it wasn't a fake 3D window manager, it was a real 3D file manager. It is actually named fsn and you can read about it and download it from here [sgi.com].

    No, it's not. Monitors still max at less than 150dpi.
    Until they're at *least* 250 dpi I'll still want antialiasing.
    Just because you read it on slashdot doesn't mean it's any where near true.
    Inform yourself. Don't parrot back what some ill-informed slashbot said.
  • There are two fundamental problems with three-dimensional user interfaces:

    1. We cannot see three-dimensionally. We see only a two-dimensional projection of the three dimensional world plus a little depth information. If you close one eye, you lose even that.

    2. A monitor is two-dimensional. You can emulate the third dimension, but it really isn't there. Thus, on a monitor you don't have depth information either.

    A three-dimensional interface might be worthwhile if we had big holographic displays in which we could enter and interact with, similar to a "holo-deck". But until we have that kind of technology, I believe 3D user interfaces are not going to make significant inroads, especially not if they take the approach of 3dwm, namely moving 2D windows around in a 3D world. 2D window managers let one manage windows quite efficiently today. There is not much to gain on that front.

    I'm one of the core developers of 3Dwm, and I've watched with horrid fascination as the webserver was nearly toppled by the tremendous /.-onslaught just recently (have a look at the logs [chalmers.se]). Now, browsing the comments, I thought I should post and clear up some points.

    First of all, yes, 3Dwm is misnamed. 3Dwm is NOT an X11 window manager, it is a user environment (the beginnings of the 3D-equivalent of X11). However, the name has stuck with us since our first appearance [slashdot.org] on Slashdot, so we don't want to change it.

    Secondly, the main platform for 3Dwm is not normal desktop computers (though it does run on desktop systems), but Virtual Reality devices (like this [chalmers.se] one). In Virtual Reality, you have some amazing 3D interaction possibilities that few existing applications exploit.

    As for VNC [att.com] support, 3Dwm has VNC client (not server) functionality, just as one observant slashdotter pointed out. This allows us, in a network-transparent fashion that is in keeping with the distributed nature of the rest of 3Dwm, to display graphical desktops of any major windowing system (including Windows, X11, and MacOS) in 3D.

    There's always skeptics who wonder what you would use a system like this for when 2D is perfectly fine. To that I can only answer that there are, in fact, areas where 3D could help a great deal, mainly in the fields of design, modelling, and information visualization. Why, take a look at this [chalmers.se] (and this [chalmers.se] and this [chalmers.se]) screenshot for a prototype 3D web browser.

    Btw, today marks the one-year anniversary of our last slashdotting (I wrote up a short summary [3dwm.org] of the comments we got last time). Cool, eh? :)

  • Let me get this straight you are going to have something with the memory footprint and processing power that quake needs and add that to a window manager? Isn't Enlightenment powerful/wasteful enough?

    One word for you: antialiasing. Finally a way to have antialiased text in X. That's worth two 3D accelerators and another DIMM if you ask me - if you spend as much time staring at a display as I do, you may agree.

    Sure be nice if there were a cheaper way to do it though. :P
