    A couple of comments here mention using this in VR. Fwiw, years back I played a bit with shallow-3D UIs for software dev. Shallow like within a few cm of a laptop display, to minimize VAC eye strain for all-day use. Think more being able to layer and draw in color, but in 3D, rather than waving arms in a room.

    The 3D can be wiggle 3D, or perspective from webcam head/eye tracking, or stereo from shutter glasses, or XR HMDs. Wiggle is easiest - just move the object orientation back and forth. Cute but distracting. Well, cross/parallel-eye gaze is easier, but limited - ok for little UI test swatches. Perspective is more subtle, less intrusive. Can be simple with a head tracker driving a single orientation, or go all in with eye pose (for distance) and window locations, to do an accurate 3D render. App stereo pairs can be "I give you two windows Left/Right-eye", or "alternating L/R view, labeled/synced/polled". Other possibilities. Many of these need window system/manager/desktop support. I found a lot of leverage in using a stack of electron and X.

    It's fun to displace text in 3D. Like colorization, but more so. And if you don't mind a cluttered appearance, you can add secondary information layers segregated by depth. And... etc. Emacs with characters-have-a-depth finally gets you something LispMs didn't have. Fun aside, to explore possibilities with code text, with anything not inherently 3D, far easier to prototype UX with fg/bg colors, fonts, unicode, and animation. Or in browser, overlaid divs and transparent 2D/3D canvases.

      I have a working fully 3D glyph based text rendering system I can't seem to get people to look at.

      It's this. Every character is a 3d placed quad, instanced rendered, so you get tens of millions and then some. They are individually addressable and mutable like any polygon. I use it to render entire GitHub repos in one go. I have two versions, native Apple and web. Web has the basics of an ide setup. Would love insight or thoughts.

        Is there a reliable way to pan around? Middle click + drag doesn't pan if my screen is covered by an object, it just moves the object itself. Scrollwheel pans up and down but I can't figure out how to go left and right. The minimap is too coarse - when I'm zoomed in close enough to read any text, very tiny movements of my mouse on the minimap pan around massively, too massively to be useful.

          Two things, one is wrote, the other is direct: Thank you, sincerely, an immeasurably appreciative amount for trying something new, sharing your time and opinion, and being honest with it. This is how we become better tool builders and engineers: different perspectives, different ways of thinking, and honesty with others. Again - thank you.

          Ok, now for you: Interaction is absolutely not ideal. I've tried a number of 'defaults' across the years and across platforms, and this isn't the one I want to settle on. At the moment, the 'shortcuts' and bindings page is also a bit out of date, but you can change scroll / zoom directions with keyboard modifiers, and they keyboard itself (if on a device that has one) can be used to navigate around. Agreed that scaled interaction is the trick to this when reading individual files, and that's why I have tried to allow this to be configurable and dynamic while testing. Some people want big picture motions first to get a mental map, some want to focus on small groups of individual files to read. I'll be taking this into account!

        I opened and it said to use a repo tab. There are no tabs so I pushed a button. It had a list with Linux so I clicked that. It redirected to a 404 page on github and I gave up.

        I don’t know what this is supposed to do, let alone how to use it. But I looked at it for you!

          For you: The 'tab' layout is pretty atrocious even as a one-shot run through of fitting most of the control areas to mobile and desktop screens. It's not easy, and a lot of 'feature' bloat makes it worse. Knowing what your first-time drop in was like and how you found that link is incredibly useful insight, and I'll be updating the layouts more to accompany first timers and instructions like the original source material I'm rebuilding from on the Apple side.

        it opens source files in an unreadable small size, presumably to fir the whole file into the window. i can zoom in, but i can't properly scroll around or select text. and i don't see the benefit of using 3d here. it doesn't seem useful.

          For you: You're probably right about "not seeming useful", but I do wanna gently nudge you toward what this is a proof of concept about again. Most folks look at this like it's a bigger, flatter emacs/vim/Sublime/VSCode or whatever. I do support editing in my current workbranch, as well as command-based selection, but most of the work spins out because the tool is half "adopt what tools are useful to an interactive development environment of today" and "allow the display of the canvas to overlap with the spatial relationships of directories, files, and colocation to help generate mental mappings of a code space".

          These things have often been in conflict, and years (decades) of prior art show this. This is my attempt at it, and since it's my 3rd attempt in twice as many years to make it work in a new environment, you're hitting this particular instance's walls. Would love more feedback or questions!

          Second up: I'd love some input as to what didn't work! Did a shader fail to load? Desktop or mobile? Did you load a repository that was too large and OOM'd out in the browser? Did it cause your monitor to spin 360 degrees and speak tongues? Do tell!

            Second: Thanks for the confirmation! If you've got any thoughts or feedback, please be as direct as you'd like - I've already started cleaning up some of the more 'user friendly' notes I've been neglecting in an effort to stick to the internals.

        that's a poorly chosen counter-complaint. before SGI, symbolics owned the market for 3d graphics. this was a world where you could also just do (create-window), see the window, and get back a handle you could use to draw in it. starting with X10 afterwards for me was like drowning in mud.

        • tombert 23 hours ago
          I've dug around the TempleOS codebase a bit, and while it certainly is impressive for a single guy's work, I think there's been an overcorrection where people act like Terry was some hyper genius instead of "a pretty smart guy".

          I kind of got the impression that whenever Terry didn't know how to do something, he would just convince himself that that's not what God wanted anyway and stop doing it.

  • noelwelsh 1 day ago
    I like this. No reason the terminal should only support text. Data science notebooks show one way the terminal can evolve. Lots of interesting stuff happening in this space, with Kitty probably being the most aggressive innovator here [1]. I'm not sure there is an overall vision, though.

    • joouha 1 day ago
      No evolution necessary! With my project, euporie [1], you can have use your data science notebooks with graphical image outputs, HTML, LaTeX, etc, all in the terminal.

        incredible work!!

        You mention using this over ssh. Is there any way to get this working in tmux or anything similar by any chance? Or is the idea that euporie itself is acting like a multiplexer?

        • joouha 9 hours ago
          You can absolutely run euporie in tmux. It's useful to do so when using long running notebooks over SSH, so you can disconnect and reconnect later.
      • Imustaskforhelp 16 hours ago
        This is such an amazing project. I find it so awesome that I can bump on such projects (and their creators, Hi!) on hackernews.

        I wish to ask a question if I may (and as such pardon my ignorance on jupyter kernel, I don't know much about it and I hope you can tell me more about it :-D)

        but my question is, is there a way to swap the jupyter kernel within euphorie to something else more minimalist?

        And when you run a project with ssh, there are ways to give access to other users with user:password if I may ask?

        I didn't know that there were ways to run jupyter kernels in terminal, I don't know when I might need it but I am prepared with this information now, this feels so nice to me, thanks for making it!!

        This is like a checklist of a thing I didn't know that I needed/existed but the second I know that it has existed, it feels like my mind has checked it off and just a satisfaction from knowing projects like these existing.

        (I think in some sense this is a bit of same reaction to me on Ratty too), Its just so good seeing projects in these spaces :-D

        Edit: just remembered the one time I think I was using some websites which gave me jupyter and then I tried to use browsh to run jupyter to run jupyter in terminal so that it can be controlled by terminal but it had some issues and I wasn't able to run it.

        I also wish to ask if there is a way to sign in to jupyter instance like that itself perhaps? (IIRC it was a jupyterhub instance)

        • joouha 5 hours ago
          > is there a way to swap the jupyter kernel within euphorie to something else more minimalist?

          You can use euporie-console for a REPL-like terminal experience (still with rich outputs) if you don't want the full notebook experience.

          You can also select the `local-python` kernel in euporie to run code using the local Python interpretor which runs euporie, instead of connecting to a Jupyter kernel.

          > And when you run a project with ssh, there are ways to give access to other users with user:password if I may ask?

          > I also wish to ask if there is a way to sign in to jupyter instance like that itself perhaps?

          euporie-hub supports spawning notebook instances for connected users, but I haven't implemented collaborative editing like JupyterLab supports (yet). I believe that jpterm [1] might support this.

    • pjmlp 3 hours ago
      It doesn't, that is an issue with how UNIX terminals came to be, and the whole backwards compatibility pretending that an HiDPi screen is a VT 100.

      Terminals on other operating systems that grew up with a framebuffer don't have this limitation.

          > Sometimes I wonder what he would have done if he had not gone crazy.

          At what point do you consider he had "gone crazy" relative to the development of TempleOS? Only when he committed suicide? Shortly before then? Last ____ years of his life?

          Without trying to sound insensitive, I'd personally argue the entire OS was the byproduct of a "crazy" individual.

          • compass_copium 22 hours ago
            I took the parent comment to mean, what would Terry have made if he wasn't crazy and didn't make a God-themed novelty OS?
          • drakythe 23 hours ago
            The inspiration may have been all "crazy" but the implementation was still really neat, and it takes a lot of effort and skill to get to the point he did before his death. The thing about people who lose touch with reality is that their efforts to create or express something often make no sense to the rest of us. TempleOS, however, works. Terry create an OS from scratch, an entire new language (or variant of a language) in the form of HolyC, and not only does it all work together in a way that requires no disconnect from reality, it works well for his goals and philosophy.

            The entire thing may be the result of a person suffering from schizoaffective disorder, but that person still held a great deal of skill to implement that idea and enough of a touch with the reality of computer hardware to make it happen.

    • alias_neo 1 day ago
      I wonder if something like this could work for thumbnails in the terminal; I prefer to browse my filesystem from a terminal rather than the point and click file manager typically, and it would be really useful if I could have a grid-style `ls` with terminal based renders of the 3d models (thinking STL/STEP, 3D printing) in that directory. Bonus points if I could preview/rotate the model to inspect it.
      • em-bee 1 day ago
        as a compromise i started using nemo/n̶a̶u̶t̶i̶l̶u̶s̶ with a plugin that puts a terminal at the bottom of each tab. so i have a graphical view of the terminal but a commandline in the same folder right next to it. the two don't interact other than being able drag and drop filenames from the filemanager into the terminal, so it is far from what we really want, but it's a small start.
        • passivepinetree 22 hours ago
          Do you mind sharing a little more about the plugin you use? A quick online search wasn't very helpful to me but I've also been hoping for something like this.
          • em-bee 21 hours ago
            i am using the nemo filemanager which is a fork of an older version of nautilus. https://github.com/linuxmint/nemo-extensions

            fedora has a package for it. just installing it will make the plugin available so it can be activated within nemo preferences.

            one problem is that common terminal shortcuts are captured by the filemanager. ctrl-c for example will copy a file from the file manager and not kill a process in the terminal if you have something selected (there is no shortcut to unselect everything (you can do ctrl-a,shift-ctrl-i (select all/invert selection))).

            if any shortcuts bother you, these keys can be changed in ~/.gnome2/accels/nemo

            i wish the shortcuts would work based on where your focus is.

            as for nautilus it appears that it no longer supports the APIs needed for the terminal: https://github.com/flozz/nautilus-terminal

            dolphin also supports builtin terminal, but it shares the same terminal between all tabs which is a bit less convenient. it handles control keys a bit better though.

            despite its shortcoming this integration has changed the way i work and got me interested in exploring better solutions.

            now when i want to run a command i go to the right tab, the visual presentation of the contents tell me that i am in the right directory, and i can run the command in the right context.

            i do a lot of stuff in the terminal, but i prefer a visual orientation. i normally use tmux everywhere, and i have a tmux window open for each directory that i operate in. but ls or terminal file managers are not visual/interactive enough. sorting for example depends on the use case. in a file manager i can have different tabs sorted as i like, in tmux i would have to remember the right ls command and then still don't see everything i need, especially selecting multiple files for opening at once in the terminal is a lot of typing, whereas in the file manager it is a few clicks. a separate terminal and file manager window would make it difficult to keep the two connected. (although a window manager feature that allows me to connect windows would be cool)

      Mix this 3d graphics, with data science notebooks, with local LLMs, and perhaps an integrated coding harness, with visibility over your personal data and you’d have something absurdly good.

        • em-bee 23 hours ago
          well, almost. if emacs offers a graphical file manager i'll consider using it. this seems to be a start: https://github.com/emacs-eaf/eaf-file-manager. the file manager needs to also integrate with a terminal though so i can run unix commands in the same directory. and it needs to support mouse-based operations too. finally, and that's the real kicker, i'd like a better integration of the terminal output and the graphical display by supporting the passing of structured data that the display knows how to handle without terminal escape codes. those need to go away. (which is why sixels are not a solution either)

      > push the state of terminal emulators forward

      What's overlooked here are the insane political and economic forces that were required to get anywhere close to the (sort of!) consistent implementation of plain text we have today. These projects try to piggyback off that success yet only contribute back harm. We have standards for a reason.

      I'm not saying people can't have fun, but don't try to start a cyberpunk-inspired revolution and then blame the side effects of groupthink and software rot on everyone else when it goes sideways.

      • krautburglar 12 hours ago
        Exactly this. They are slowly turning the terminal into a web browser, just for attention. We already have web browsers. If you want something at the midpoint, make it, but please don’t call it a terminal & destroy one of the few non-trojan-horse standards that we have left.

    Seems... really good?!

    Questions:

    - rendering capabilities of this seem like it should also be able to handle 2d well, or am I mistaken? every solution I see for getting high quality 2d images or rasterization in terminal is all pretty bad. Could this do better than other solutions or is there a fundamental limit being hit somewhere?

    - What happens with ssh given that this is gpu accelerated?

      The idea that every application should ship their own glyphs because some proprietary systems do not have normal fonts, is not great. Fix the terminal instead.

      Also, if you want advanced GUI with icons, maybe you should just write a GUI app.

      As for shipping custom icons, this is not very bright idea as well. If you switch between several applications on one terminal, then one application can redefine glyphs from another application. Also, when the application terminates, nobody cleans up its glyphs. Also, this increases attack surface because font standards are pretty complicated and one will be able to attack the system by just providing a glyph. We already have programs that can break the terminal, which should never happen.

      Also, as for icons, I find emoji characters too distracting (and too large). They stand out too much and take away user's attention, breaking any visual hierarchy. The icons in terminal should be monochrome, and with thin lines, so that they do not distract you from the text and its structure.

      • joouha 9 hours ago
        I'm specifically interested in querying for support of particular glyphs (e.g. the symbols for legacy computing block), so applications can use a different fallback if it is know that a particular glyph cannot be rendered and will break the interface.

        I agree that the addition of sending custom glyphs to the terminal is potentially problematic.

    This is kinda possible already today with the Kitty graphics protocol, I made a demo here of rendering 3D graphics[1] with kitty. The actual important missing thing (and which ratty seems to also not include) is vsync.

    If rendering is not aligned then it's possible for the terminal emulator to read the framebuffer while the application is writing to it, causing visual artifacts.

    The question is - why do we still need the terminal abstraction at all?
    • gavmor 22 hours ago
      The terminal is keystroke-driven. It's character-selectable. It's reliable in a way that the GUI is not. When I drop frames, I can still enter the commands to rescue myself with some assurance they'll be interpreted, eventually.

      I agree, a REPL isn't Unixy in the streams of text kind of way... or is it?

      • mr-wendel 22 hours ago
        Let me add more! PIPES.

        It's a bit more abstract and useful than "character-selectable" when viewed at the byte-level abstraction.

        The ability to chain together utilities with no complicated data structures is extremely flexible. One of my favorite current use-cases is using FFmpeg to process RTSP streams that send output (e.g. high quality stream for recording, low quality low FPS for processing, max quality low FPS for stills, etc) to separate file descriptors. FFmpeg doesn't care whats on the other end (e.g. redirect to file, read via Python, etc) due to these lovely abstractions.

        Reliability translates directly to scriptability. Yes, you can create monsters, but through the use of sub-shells and pipes I think it's the fastest, cheapest, most concise way to pull off some really cool multiprocessing tricks.

    • bsder 11 hours ago
      > The question is - why do we still need the terminal abstraction at all?

      Because nobody is willing to put in the work to create a GUI toolkit that doesn't suck ass.

      It's not that people want the "terminal abstraction". What people want is "Put <thing> on screen without me needing a PhD in graphics programming." That's why the dominant desktop interface paradigms have become TUIs and a Browser-In-A-Trenchcoat.

        Lack of imagination doesn't mean this isn't innovation.

        It's the ability to convey more information in less space.

        Top-of-my-head notion: The cursor spins (or changes in another way) to reflect CPU use, or bandwidth use, instead of taking up space elsewhere on the screen.

        • dkersten 20 hours ago
          The same was said about Compiz, but it turned out to be a passing gimmick that looked flashy but didn’t really add anything. Sure you could always make up reasons why it’s useful, I remember the same about Compiz, but… is it really? I could be proven wrong, of course, but it hasn’t been demonstrated yet.

          It’s a solution in search of a problem. OP should have presented it with a real use case or benefit, not just flashy graphics, if it’s meant to be anything other than a fun oddity (which, to be fair, is perfectly fine).

    I built DeepSteve (https://github.com/deepsteve/deepsteve) with a similar itch but went the other way. Instead of adding graphics to the terminal, I put the terminal in a place that already has graphics.

    I kept trying to optimize my terminal layout and realized I could just run my terminals inside of the browser, and let Claude Code write JavaScript in the same browser tab to customize the experience however I want. It's kind of a terrible idea, but it's my terrible idea, and I love it.

    • wonger_ 21 hours ago
      Have you ran into any issues with handling inputs? Like how vim Ctrl+P would maybe be intercepted by the browser Ctrl+P shortcut for print.

      And have you run into any other issues, maybe like performance?

      I feel like web-ified terminals get nerfed pretty hard and I'm not sure if/how people overcome that.

      I like the idea of customizing multiplexed terminals with on-the-fly JavaScript, tho.

        I haven't seen any performance issues for Claude Code, even when I'm running like 20 in one browser tab and looking at them all at the same time (rendered with xterm.js), but Gemini and OpenCode flicker a lot even if you have one open.

    • MayeulC 16 hours ago
      I have been thinking about this for a while. It's not as crazy as it may sound, especially in light of the other comments making a parallel between terminals and notebooks.

      A few thoughts:

      1. Linux VTs kind of have this feature already: there is the normal buffer, the alternate buffer (that something like htop would draw on), and an IOctl can change them to/from graphics mode.

      2. It makes sense for interactivity. Kitty's graphics protocol is quite useful for static shapes, can be abused for animations, but doesn't really cut it for interactivity (say, pan a graph around). Wayland is designed for this.

      3. Wayland would be a good fit: isolate each command from another, let them request buffers, but keep control of where to display them, do not update them when off screen, etc.

      4. One downside is that terminals excel for one-shot tasks. What's the purpose of the display when you are done with it? Should you kill the process driving it? Due to this, it may make more sense to delegate more features to the terminal emulator (displaying the 3D model, etc). Or maybe just allow the app to temporarily take over the window.

      5. Once you have it up and running, have it talk directly to the direct rendering manager. Your "kmscon" is now your compositor / desktop environment. That's a fun thought! Add some basic terminal features like tabs and tiling, and you've inverted the usual setup.

      6. One downside is accessibility. I really like that I can copy-paste any part of the interface for reference, "screenshots", etc. It's good for screen readers, too. You lose these advantages by going to Wayland.

      7. Another current terminal limitation is fonts. Power line, yazi & other make use of custom fonts for drawing part of the interface, logos, etc. AFAIK there is no good way to query their availability (which is also an issue for color emoji). Custom fonts or a new protocol could be useful, but client apps could draw it themselves if given a surface (that can already do that with the kitty graphics protocol, mind you)

      Obviously I am not seriously considering to make such a terminal emulator, but it would be an interesting experiment (heck, maybe something I should try this "vibe coding" with, since I wouldn't want to spend too much time on it).

            So just to be clear, a human being can't think properly / straight anymore, has issues forming a coherent worldview, has regularly crazy maniac phases were he would drive like 100 miles, dismantle his car, throw away his keys but you do not accept any of this as a reasonable excuse that that particular human is not able to break out or even manifests stereotypical thoughts?

            The mental base mode you are born, is a community of christians, parents forming your mind etc. and you have to break out of this, formulate your own independet worldview. A lot of people can't do that today. All religios people in fact.

    Really fun project! Dude, I spent the last week implementing Kitty Graphics and Clipboard protocols in ghostty-web in the Canvas render.

    Then I added WebGL and WebGPU renderers [1], including support for Kitty.

    Then I see this this project on a Monday morning... so now I have to implement Ratty Graphics Protocol?!?! [2].

    ETA: I looked into this; Ghostty would need patched to support Ratty since Ghostty-Web now defers APC handling there. It would also require pulling in a 3D engine like three.js or otherwise implementing file parsing, lighting, etc. Finally, since local filenames are part of the protocol, a browser would need some file resolver helper, either to get the data over the APC channel or via a URL.

    > When I first got introduced to [TempleOS], I was shocked and impressed by the flashy colors, graphical sprites and uncomprehensible UI. There are so many things that makes it so unique, weird and fascinating at the same time, somehow.... Basically, the command line becomes the direct interface for everything. You can write code, interact with the system and render graphics all in the same place, which is why TempleOS feels so unusual compared to conventional operating systems.

    I think this could be a really cool approach. I enjoy tools like Chafa, imgcat, etc but something always feels a little clunky about the separation between text and images. Paradoxically having text and non-text all jumbled up like this feels better somehow.

                   - Then launch XTerm as 'xterm -ti 340'.  Edit ~/.Xresources so you have nice fonts:
          
                      xterm*background: black
                     xterm*foreground: white
                     xterm*loginShell: true
                     xterm*faceName: Monospace
                     xterm*faceSize: 10
                     xterm*geometry: 100x32
                     xterm*metaSendsEscape: true
           
           
                     xterm*decTerminalID: vt340
                    xterm*numColorRegisters: 256
                    xterm*sixelScrolling: 1
                    xterm*sixelScrollsRight: 1
          
          
          Done. Edit the facesize value to a bigger font if you have a big resolution. Run "xrdb ~/.Xdefaults" to get the changes.

          Also, you can run chafa locally with images such as "chafa -f sixel --fit-with foo.img', no need to login into a VPS, of course, it just was a proof of concept that you could see images over SSH. This can be really useful for instance to read graph/plots with Gnuplot or similar tools.

          If any, subscribe to T3X's news letter and get some books, as these small tools will pay a lot in near future. No AI crap, small enough to run on some sets, from Statistics to semi-advanced math (even Zenlisp being crap can do complex numbers, and you can adapt the code for instance for S9 so that interpreter Scheme understand complex numbers and a much faster speed).

          Yeah, Python+SAGEMATH, CUDA with number crunching and the like. How much are the GPU's, CPU's and SSD's going nowadays in dollars?

    What a twist, having textual window manager within a graphical user interface, and that textual window manager implementing bits of graphics.

    You'll soon may be able to implement overlapping graphics windows in TUI within GUI.

    This is stupid af.

    My first reaction: "But why?"

    My second reaction: "Oh wait is that TempleOS being cited? This is either awesome or terrible."

    > inserted 3D objects in the demo above are actually from the TempleOS codebase itself

    Brilliant. The dream lives on! This is the best form of paying respects.

    It's walking a fine line between madness and genius, and who knows if it'll ever be practical, but more important is the sense of wonder and "fuck yeah" as King Terry expressed so eloquently.

    Excited to see others equally inspired by TempleOS’ 3D feature :)

    I tried something similar a few months ago that acts more as a library to ratatui than a separate terminal emulator [0].

    Was surprised how far one can get using some off the shelf characters like half-block when rasterizing.

    The Glyph protocol mentioned in the blog post is interesting … perhaps custom glyphs could help smooth some of the (literal) rough edges from the low effective resolution of a terminals character grid.

    Can anyone explain why this is novel? It seems pretty basic?
