Flex and Augmented Reality, Preview not working

Question

Hi
I have been following the tutorial  Introduction to Augmented Reality on gotoandlearn(http://www.gotoandlearn.com/play.php?id=105).
I have followed the coding exactly  and yet nothing happens when I go to preview it.  I have even copied the  code in the provided code (ar.zip) into my project and have had no result.  When I go  to run the application inside Flex, the Flash Player opens with the  default Flex coluring but nothing occurs inside, Eg the camera is not  called up etc.
I am using FlexBuilder 3 with Flex 3.5.  With  Flash Player 9.
Here is the code (basically pulled straight  from the downloadables)
package {
   import flash.display.BitmapData;
   import  flash.display.Sprite;
   import flash.events.Event;
   import  flash.media.Camera;

   private  function setupCamera():void
      vid = new Video(640, 480);
       cam = Camera.getCamera();
      cam.setMode(640, 480, 30);
       vid.attachCamera(cam);
      addChild(vid);
        private function setupBitmap():void
          bmd =  new BitmapData(640, 480);
          bmd.draw(vid);
           raster = new FLARRgbRaster_BitmapData(bmd);
          detector = new  FLARSingleMarkerDetector(fparams, mpattern, 80);
        private function setupPV3D():void
          scene = new  Scene3D();
          camera = new FLARCamera3D(fparams);
           container = new FLARBaseNode();
          scene.addChild(container);
          var pl:PointLight3D = new PointLight3D();
           pl.x = 1000;
          pl.y = 1000;
          pl.z = -1000;
          var ml:MaterialsList = new MaterialList({all:  FlatShadeMaterial(pl)});
          var cube1:Cube = new  Cube(ml, 30, 30, 30);
          var cube2:Cube = new Cube(ml, 30,  30, 30);
          cube2.z = 50
          var cube3:Cube = new  Cube(ml, 30, 30, 30);
          cube3.z = 100;
           container.addChild(cube1);
          container.addChild(cube2);
           container.addChild(cube3);
          bre = new  BasicRenderEngine();
          trans = new FLARTransMatResult();
          vp = new Viewport3D();
           addChild(vp);  
       private function  loop(e:Event):void
              bmd.draw(vid);
             try
                 if(detector.detectMarkerLite(raster. 80) &&  detector.getConfidence() > 0.5)
                 detector.getTransformMatrix(trans);
                 container.setTransformMatrix(trans);
                 bre.renderScene(scene, camera, vp);
        catch(e:Error){}
Any help would be much appreiciated.
Thanks
Daniel.
Also; sorry I wasn't sure how to neatly display my code in the post

Answer 1

You didn't post the original, before adding the +5 exposure.
I played around in LR5 with some of my photos, and I found this one that exhibits similar results on adding +5 exposure, but it starts off as underexposed and low contrast.  Anything a bit more exposed or with a slightly brighter area (e.g. make dog's front leg a tiny bit brighter) does clip.  (Note - this is the original photo without adding any exposure).
