    When certain fonts are displayed in Windows, certain characters are cut off on the left. It seems when the bounding box of text is calculated, it is incorrect, allowing some text to be cut off when displayed. I've noticed this is IE and Word especially.

    Hopefuly they can fix this in the new fonts.

      All you need to do is figure out the A width of the leftmost character and adjust accordingly. The question is whether or not it is correct to do so. For some characters, probably not.

      This is why things like Adobe PageMill now do optical kerning; it's not a simple matter of just "fixing it in the new fonts" - and it's not something you can easily automate.

    Joe Beda had said that Avalon is going to be more of an advanced UI/Visualization toolkit, while Dx will continue to contain all the other serious stuff.

    Now, it looks like Avalon can do 3d on it's own and maybe more too -- what's the idea behind this anyway?

    Are they trying to get a fresh new API or something? It seems unlikely, since I remember Joe and Scobles saying that they will probably be using Dx for serious graphics and game development. The redundancy seems strange.

    From the presentation --

    Avalon 3-D are not a replacement for Direct3D
    You will find Avalon 3-D useful if:
    - You want to integrate 3-D seamlessly into an Avalon app that also contains 2-D content, controls, etc.
    - Platform features like Remote Desktop and multimon are high priorities for you
    - You want to easily add 3-D functionality without quickly without needing to learn how the graphics hardware works

    You will find DirectX useful if:
    - You want access to all of the features provided by the graphics hardware
    - You want to have full control over how your scene is stored and managed in memory
    - Plan for interop between Direct3D and Avalon
    Render Direct3D in a HWND and host within Avalon


    So basically it seems to help ease the creation of bells and whistles, more than anything. Weird.

        Except the difference with Avalon is it uses hardware to render the individual windows to their own textures, and then uses hardware again to composite the textures on the desktop. Everything that can be done in hardware will be, vectors, gradient fills, antialiased text, etc. with software fallback available only for features the hardware doesn't support.
        You can use hardware to render a texture too you know.

    Apparently an Aero testing suite will be released at least 18 months before Longhorn's release. Is this demo yet available? It's interesting to note that if this message is right, Longhorn will not be available until 2006.

    Will MS publicly announce this Aero test, so that we can anticipate a real release date for Longhorn?

      I think the technology is OK, but overbuffed beyond recognition. Comon : they have a screenshot of a 3D bar graph behind some semi-transparent buttons. Cool maybe, but then they boast having done it in 2-3 days.

      duh ? I don't know how many whistles are behind it, but putting a rotating 3D object in an app can be done right now with a few clicks and a few lines code adding an ActiveX control to an ordinary MFC app. Putting transparent shit on it is supposed to be OS-level, so that should take 2 minutes once the OS supports it. What were they doing 3 days ? It can be done TODAY in less time. On Windows. On a P3 with 64MB ram.

      that's what I hate the most about these presentations. They fart in a bottle and present it as the new coming of Christ. And everyone buys it.

          This is an important distinction, and one I remember noticing when seeing other people use Windows 2000 (I think) after I'd been using osx for a while.

          Windows's idea of eye candy was that menus (and submenus) would all slowly fade in. The process of navigating deep into hierarchical menus was maddeningly slow--at least until everyone turned it off.

          In osx, menus appear immediately, and then fade out after you select something. This is not only pretty, but functional: it gives you visual confirmation that you've selected a menu item, which can be helpful if whatever you've asked for doesn't produce obvious or instant results.

          Microsoft's cargo cult [wikipedia.org] design process often leads them to such mistakes. They manage to take the wrong lessons from other people's work, and conclude that what people want is snazzy looking things which tax hardware. The real lesson is that people want visual continuity and feedback in order to speed up their use. But Microsoft never seems to get as far as understanding the point of anyone else's design, just the appearance.

    • While I have to admit it sounds cool, I can't really think of a real need for this.

      And while you are at it, I think I speak for everyone when I say I can't think of a real need for Longhorn either ;-)
        • I'm using gentoo primarily, and I have a box running Fedora Core 2. Bluecurve is nice, but it still can't hold a candle to Mac OS X or Longhorn (from the screenshots I've seen). With SVG now implemented in GNOME, it would be my guess that there will eventually be a big wave of pretty vector-based icon sets and themes. I sure hope we will be able to compete against the big guys (Microsoft) though.

    No, not hot.

    But reading Avalon's text support it seems that Longhorn will FINALLY be able to have the same deep text support that OS X has had since at least 10.0. Yes, all the APIs are marked AVAILABLE_MAC_OS_X_VERSION_10_0_AND_LATER with most of them having support in CarbonLib 1.0, ATSUnicodeLib 8.5 (Mac OS 8.5). Nice to see longhorn might finally be catching up.

    The only thing that longhorn claims it will have that ATSUI doesn't have yet is the graphics card rendering support. Ever wonder why resizing a window is so slow on OS X? ATSUI is the reason.

      Graphical Composition in Avalon [ondotnet.com]

        • by SuperKendall (25149) * on Monday May 24 2004, @12:43AM (#9235183)
          The real meat of the whole thing starts here [oreillynet.com].

          A really, really long chain of postings between the guy who wrote the article and a guy who seems to know OSX rendering pretty well.

          My take on this is that OSX has tacked a lot of issues with making vector display practical, and trying to maintain a good balance between "everything is a vector and you all need new computers to run the OS" and "everything is a bitmap and you can run this on a 286". Personally I think a lot of graphic designers will be aghast at the limitations an all-vector approach will impose for things like icons - you can see guys spending days tweaking pixels. You may think you've done them a favor by taking that options away, but these are the guys that make your interfaces look good! Treat them nice, I say.

          I would also say each is holding his own pretty well in this argument, it did not get too far into name calling and the like (gets more technical as you progress - my link takes you pretty much to the point wher ethey drop the childish bits). I do think the Avalon guy is a little more ignorant of what is going on in OS X rendering-wise than the OS X is of Avalon - the OS X guy for a while was unwilling to believe that anyone would actually take an approach with only vectors, but understood fully that aspect later on.

          The Avalon guy has a good point that it's cheaper to send a lot of vectors to the GPU than to calculate very high DPI images for display... but I think the OS X guy has a good point that you can't have the GPU do everything.

          Here's a simply summary from my read (not comprehensive):

          Article guy: Maintains the vector retained model is the only scalable UI solution. UI's should only be collections of vectors (including all icons and the like) with everything, even text, being rendered by a GPU on your video card.

          Also maintains that parts of OSX are not really PDF/DPS based, and therefore will not scale.

          Has not yet answered if he thinks it's a good idea for the GPU to be doing typography (like kerning).

          Longhorn will require new GPU's for sure, from everyone.

          Avalon target is display showing about 10,000 primitives.

          Avalon targeting high (300dpi+) displays, only path to good performance is feeding vectors to a video card.

          OSX Guy: OSX does use PDF/DPS model correctly, elements will scale - renderer can be set to any DPI. To use the GPU for all drawing operations is madness - OS X has quick operations for things like video, and slower but much more exact operations for things like 2D operations. To use GPU for all operations is going to be a disaster as they cannot handle quality 2D operations (like exact text rendering) all that well.

          Showed how saving a window as PDF yields scalable elements (not just a raw bitmap).

          Maintains that OS X can support high DPI displays, you just change the rendering target.

          Can rotate window contents in real time.

          Expose is not supposed to be an exact vector resizing as such an operation should be very fast, not exact.

    According to Raymond Chen [asp.net], during usability studies people remarked that XP's Luna would be a great UI for their dad, employees, etc., but didn't want it for themselves. Now, when they look at Aero, it's "Wow, this would be a great UI for me to use." Most of the people participating in these studies are probably not part of the Slashdot crowd, though. And Raymond Chen works for Microsoft, so he's obviously the Boogeyman. So take his post as you will.

    Windows seems to be going down the road of "show fewer things but with bigger pictures", which may be great for regular folkum. Advanced users will just scrap the bells and whistles anyway for a basic, functional setup. "Dumbing down" through simplification isn't always a bad thing though. I actually like the new WinXP start menu a lot better than the classic one, albeit with small icons instead of the huge default setting. Silver Luna isn't too bad either, as long as I reduce the size of the titlebars and buttons to classic size. Again, what's the deal with Microsoft and huge buttons and icons? Are they trying to cater to the bad eyesight but too cool to wear glasses crowd?

    • Again, what's the deal with Microsoft and huge buttons and icons?

      Try running XP with 1600x1200 with 20.1" diagonal (my flat panel) or 1400x1050 with 14.1" diagonal (my laptop). Anything smaller than the "huge" icons is quite tiny.

    In the immortal words of Colonel Kurtz, "You must make a FRIEND of the horror".

    What horror, you ask? A major Microsoft upgrade. We cal look forward to the following exciting experiences in the coming Longhorn apocalypse ("I love the smell of burning CPU in the morning... It smells like... Job Security!"):

    1. Indigo, the new .Net secret sauce coming with Longhorn, will no longer use Remoting "over the wire". Everything is going to be SOAP and web services. Sounds wonderful, right? I think so too. BUT, many consultants are busy writing all your company's apps using remoting between servers! Guess what THAT means?

    2. All your computers are going to be landfill fodder, because Longhorn's hardware requirements are going to SMOKE 'em. Ah, well, we didn't need those 20,000 PCs anyway. And, the budget looks so much better cratered. It's like a big empty swimming pool. Makes me think of summer.

    3. Performance? The users are asking about performance? Um... HUSH! Look at the pretty screens, children! Ooh, transparency!

    4. Filesystem? We don't need no stinkin' filesystem. Let's put everything in a DATABASE!!!
    Ok, they might not get this into Longhorn, but it's coming. All your apps that touch the filesystem? Kiss 'em goodbye.

    5. More DRM. What's that? the users didn't ask for it? Let's surprise 'em; they'll be so happy!

    6. A new, different and strange iteration of IE to worry about. Sigh; better set up resources for the recoding of all your web pages, just in case.

    Ah, well. It should be exciting! And, who knows? Maybe the Indians will find it all just too ugly to work with and offshore all the work back here ("Oh, this is just too UGLY, you may take it back, please... No, really. No, I must insist. Oh, you are too kind, sir, but NO, I REALLY must insist... Oh you are making me very ANGRY sir, do not make me go medaeval on your unruly buttocks in the manner of Marcellus!").

    I believe this should, mind you, SHOULD raise the heat under the open source movement.

    Do your OS of choice under the following:

    Make it so it runs on anything from legacy hardware through current hardware.

    Don't engineer it specifically as how YOU would want it done, engineer it as how you think Joe Sixpack would like it to be done. Do you know how MS keeps its market share? By making adaptive shifts to their new setups as small and painless as possible. Stop assuming everyone who wants to try Linux already knows every manual and howto available.

    Screw the DMCA, reverse engineer everything (do it the old fashioned way, get 50 coders to examine 1/50th a part of the driver code, then compile accordingly, that's how it was done with IBM). That way everything can be supported.

    If you want to be mainstream, start acting like you ARE mainstream. This "Lookit me, I'm a rebel!" illusion is just that. That's how Apple did it, that's how Microsoft did it. And look at them now. The rebel theme is only good as long as you expect to lose money.

    I'm a MS user myself, but the DRM crap and all makes me WANT to go Linux, but the fact that not every Linux dev doesn't support EVERYTHING I want to do or use, means I'm stuck with MS until they realize this.

    The text rendering technology impressed me. The new APIs did not.

    When will Microsoft learn...developers don't want great big heaps of their grand designs. There's just too much of an investment to learn their way of doing things, there are too many cages around the good bits, and everything breaks when you go off the beaten path.

    Example: few 'real' apps use MFC - and certainly none of Microsoft's. They expose 'Fisher Price' versions of their tools which they hand code in good old SDK.

    I mean, does anyone *really* use DCOM? I guess COM has held on bascially because there isn't that much that is 'Microsoft' about it and it basically works. But what happened to ATL? DDE? ActiveX? In fact, the only useful Microsoft software tends to be the stuff they acquire (Visio, SQL Server)

    Now I have not used one iota of Avalon, but I remain unconvinced it will be anything other than their typical developer traps with a bit of 'hello world' cute app as bait.
