Hey Guys,

I’ve done some searching on these forums and Google with no results.  I’m looking to update my augmented reality application and I’d like to know if anyone has any insight into how I could get Flartoolkit up and running in Away3D 4.0 and Flash 11.  Currently I’m using Papervision and I’m experiencing considerable performance lag.  I was hoping with the advent of Flash 11 I could switch to Away3D and get some huge performance improvements.  Let me know if you guys have any input at all, and maybe you can point me in the right direction.  Thanks in advance for any help you could provide.

I’ve done the exact thing you are trying to do yesterday.
I just wrote a Detector Class which is an almost exact copy of the FlarManager Example class that uses Away3D 3.6 to display models.
Stripped it of the 3d elements, and only used it to get the transformMatrix.

I can send it to you if you still have problems to understand it.

Hey Animaleante,

I gave it a shot and I was having a little trouble sorting it out.  If you wouldn’t mind sending it or elaborating I’d really appreciate it.  Thanks for your help!

I was going to go throught and convert for Away3d 4 too, but if you;ve already done it…

Hi guys,

If someone has some working code for Away3D 4.x I’d be gratified to see/get it.  The transformation code is completely unusable from the Away3D 3.4 version of the FLAR library.  I could see this working quite nicely if that part can be repaired; I’ve tried unsuccessfully so far to get it to work.

Thanks,
Alan

Hi! i am trying to make it work too. All is right except this error:
not defined zoom on //this.zoom = 0.01 * this.flarProjectionMatrix.rawData[0];
how i can make it works??

I have remplaced in FLARCamera_Away3D.as
this.lens = new PerspectiveLens();
this.zoom = 0.01 * this.flarProjectionMatrix.rawData[0];

for this

this.lens = new PerspectiveLens(0.01 * this.flarProjectionMatrix.rawData[0]);

//this.zoom = 0.01 * this.flarProjectionMatrix.rawData[0];

and run, but the FlarSource (Webcam Capture) appears above the 3D Object so its overlapping it,

this is the code that add to stage the camera view, but above the 3d object, I want it below it!!

stage.addChildAt(Sprite(_flarManager.flarSource), 0);

What i can do??

Thanks

Hi,

I’m working on too… ! I was just wondering how you deal with the stage3d and displaying cam capture. As you know the stage3d is behind the stage. The only way I found, it ‘s to display the cam capture on a 3d plane(like a movie material).

We can now use cam capture in stagevideo(fp11.2 beta) (stagevideo is behind stage3d) , but no way to have a background alpha (molehill 2 ???).

I will post my source, when I will have something working !

Here is something working (not to bad) but still in dev :

It use FP11.2 beta with the new feature Camera.drawToBitmapData.

Samuel

a test using asfeat : http://away3d.com/forum/viewthread/1292/

Please i need the code source!! a lot of thanks!!

I cant make view.backgroundImage works!! It’s correct?

myBitmapData.draw(Sprite(_flarManager.flarSource));
view.backgroundImage = myBitmapData;

Thanks!! How do you it?

I try this too but don’t work, when i put a embed image as background works but when i try to pass each frame of the webcam i only see a blank screen. PLEASE HELP!!!

private var webcam:Camera = new Camera();
private var video:Video = new Video(640, 480);
private var snapshot:BitmapData=new BitmapData(640,480);

webcam = Camera.getCamera();
webcam.setMode(640, 480, 30);
video.attachCamera(webcam);

OnEnterFrame
snapshot.draw(video);
view.backgroundImage = snapshot;
view.backgroundImageFitToViewPort = true;

THANKS!!

I try also to creat a bitmap material with the flar source for a plane but doesnt work (BLANK SCREEN):

myBitmapData.draw(Sprite(_flarManager.flarSource));
plano.material = new BitmapMaterial(myBitmapData);

THANKSS

I ve uploaded my code for flar :

Samuel,

I’m trying to use your code with flash player 11, normal video instead of stageVideo, I’ve got everything working but the fps is really low, around 10-11.

I saw your video and yours was about 14-15, have you managed to improve it?

From what I can tell, it starts to slow down here:
detected = false;
  try {
  detected = View.ar.detector.detectMarkerLite(View.ar.raster, View.ar._threshold) && View.ar.detector.getConfidence() > 0.5;
  } catch (e:Error) {}

Does anyone have an idea to improve this?

Thanks!
