   こんばんは。はじめまして。

   blogのコメント欄を見て飛んできました。

   ActionScript3版の実装成功おめでとうございます。
   私も同じ構成で作ろうとしていたんですが、先を越されちゃいましたねｗ

   JavaよりもFlashの方がユーザーに近いですし、色んな応用が出てくるんじゃないかと、個人的には楽しみにしてます。

   開発頑張ってくださいネ

   スゴス！！！

   アストロのPixelBender使って、ラベリングの処理をFlashの外に出しちゃったら、結構スピードアップするんじゃないっすか？？

   はじめまして。しのぶです。
   NyarToolkit DemoをAppletにしたりしております。

   FLARToolKitサッソク試してみました！さくさく動きますねー！
   オモロイもん期待してます☆

   みなさんこんにちわ。

   > A虎＠さん
   すいませんすいません。公開したらコメントしにいこうとおもって、ブログ書いてたらそのまま忘れてたす。
   AS3 化は実は NyARToolKit 0.7 ぐらいのときにやっちゃってて、なんかおもしろコンテンツとともに出そうとおもってたんですけどなかなかできなくって、A虎＠さんのブログにちらっと AS3 版の話がでてたんでもーいーやって出しちゃいましたｗ
   mixi にコミュなんてあったんですねー。チェックしまーす。

   > fladdict さ
   Flex でプロファイリングしてるとラベリングよりはマーカーのパターンマッチングのほうが重いかんじ。まー、いずれにしても Pixel Bender をうまく使えば高速化できるとはおもうねー。3D も Astro 版 Papervision とか出ればかなり使えるもんになるんじゃなかろうか。

   > Shinobu さ
   Applet も使ってみるっていうところでは Flash とさほど変わんないですよね。Processing から使えるようにすればそっちのがいろいろと強力な気も。。

   > れんさっ
   あー、まー、でも、そなにスゴイコトにもなってないｗ

   こんにちは。

   AS版を開発してること教えてもらえてたら、多分私は作りませんでしたよｗ
   結果として慌てさせてしまったようで…申し訳ない。

   （でもインパクトのある開発は、こっそりやりたいときもありますよねｗ）

   表示系の件、blogのコメント欄に参考にする資料載せときました。もしよければ見てみてください。

   こんにちはー　Flashへの移植おめでとうございます．
   ブログにて紹介させていただきました．
   これを応用して何か実用的なものが作れるといいなーと
   期待しております．

    Hi !
    Sorry I can’t read nor speak japanese…
    You made a amazing work !

    I just found a bug with the multi marker detector :
    file FLARMultiMarkerDetector.as, line 155
    replace
    var c2:int = match_patt.getConfidence();
    by
    var c2:Number = match_patt.getConfidence();

    Keep up the good work ;)

    Thanks, prayone!
    I’ve fixed and commited to repository.
    Enjoy!

    You guys rock! This is as close to Do-it-yourself augmented reality that I have seen.

    Many, many thanks for sharing this with the world.

    Sorry for writing in english.
    I downloaded your FLARToolkit Class, and I can’t make it work properly. I’m loading a specific pattern (patt file), but i’m getting every pattern recognized as the same. Even the example that you post, works the same with any black square drawn in a paper (it’s not necessary to print patt.hiro, it works with any pattern, wich is wrogn). If you could post some directions on this, it would be great! And… Congratulations for your work! Cheers.

    Hi, tannis.
    Sorry, I can’t understand your problem. please tell me more detail.

16. taniss Says:
    Sep 10th, 2008 at 12:09 AM

    thanks, I already fixed it. The problem is that when only one marker is on the screen, the SingleMarkerDetector takes it as the correct marker. What I did, is force the script to check the level of confidence, not against another marker on screen (since of course ther isn’t another), but to check against an average value (for example, I set 0.65). I’m getting really good results with that, actually if I point my camera to a marker that is not the one I loaded, nothing is drawn on the screen. Wich is what I needed, of course. Anything you need, please write me an e-mail, i’ll be glad to answer, and once again, congratulations for your work.

    hi Taniss, I have the same problem.
    can you contact me : tim_timmers @@@ hotmail dot com ?

    Sweet work Saqoosha!

    Hi!

    That’s really great work!
    Unfortunately I only can watch the demo. I tried to checkout (with subversion) the files but I always get an error “XML data was not well-formed”. Did I do a mistake or isn’t the code located at http://www.libspark.org/browser/as3/FLARToolKit/trunk/ anymore?
    I’d really be glad to have a look at it too!
    Thanks a lot!

    Tom

    Is it possible to detect more than one markers at the moment? I have seen the samples and its using SingleMarkerDetector. Is there any example with more than one markers?

    Thanks in advance!

    Hey Tom, I had the same problem. The proper svn address would be http://www.libspark.org/svn/as3/FLARToolKit/trunk.

    Good luck

    to psilos.
    The class org.libspark.flartoolkit.detector.FLARDetectMarker is for multi marker detection. but I have not used this class.
    If you succeed, please report!

    in response to psilos.

    i’ve had mixed results using the multimarker class. Basically what it does is take an array of markers and loops through them looking for the ar marker.
    but it doesnt work as well as the simple marker and I still havent figure out why. maybe something wrong with my code.

    heres what i’ve done:

    1. load 2 or more markers

    var codes:Array = new Array();
    var widths:Array = new Array();

    _code = new FLARCode(16, 16);
    _code.loadFromURL(“../Data/marker1.pat”);
    codes.push(_code);

    _code = new FLARCode(16, 16);
    _code.loadFromURL(“../Data/marker2.pat”);
    codes.push(_code);

    widths.push(MARKER_SIZE);
    widths.push(MARKER_SIZE);

    this._ctx.mdetector = new FLARMultiMarkerDetector(this._param, codes, widths);

    2. then create a nodes array and push the Flar nodes into it:
    nodes.push(this._scene.addChild(new FLARBaseNode()));

    3. create papervision objects and add them as childs of the nodes created:
    nodes[0].addChild(new Plane(wmat, MARKER_SIZE, MARKER_SIZE));
    nodes[1].addChild(new Plane(wmat, MARKER_SIZE, MARKER_SIZE));

    4. in your application loop check which markers are being detected:

    var i:int = nodes.length;
    while (i– > 0)
    {
    nodes[i].visible = false;
    if (this._ctx.mdetector.detectMarkerLite(this._ctx.raster, 100) && this._ctx.mdetector.getConfidence(i) > 0.5)
    {
    trace(i + ” ” + this._ctx.mdetector.getConfidence(i));
    this._ctx.mdetector.getTranslationMatrix(i,this._ctx.resultMat);
    nodes[i].visible = true;
    nodes[i].setTranslationMatrix(this._ctx.resultMat);
    }
    }

    Hi, I’ve just looked into this and it stuff is sweet.
    I’ve got a question thou. Is it possible to use a different marker rather than a square? I was thinking using a circle with a dash across it like the London underground logo:
    http://subtitlestocinema.files.wordpress.com/2008/11/london_underground_logo.jpg
    Any ideas how to achieve that?

    Thanks

    Hi Tom,
    It’s impossible to use other than the square for the marker in FLARToolKit. But you can design inside of square. Please refer http://saqoosha.net/en/2008/06/05/676/ (currently in Japanese only, sorry.)
