@tom — “all kind of errors” is not helpful in determining your problem.
if you still need help, please post more detail on the FLARManager forums.

@tom — first question, why are you using such an old version?

Am getting the following error when trying to compile using Flash CS5:
U:\Work\Flash\Class'\com\transmote\flar\utils\geom\FLARToolkitGeomUtils.as, Line 103 1046: Type was not found or was not a compile-time constant: NyARDoubleMatrix34.

@omer — you don’t really need to know how an NYARDoubleMatrix34 works, just copy the values in the correct order. however, if you want to know, take a look at the conversion methods in FLARGeomUtils.

Hey thank you so much, it wroks perfectly!

Is there anywhere an explanation for, how the Parameters of a NyARDoubleMatrix34 work?

It is realy difficult for me, to understand which parameter causes which translation / transformation!

What i’m going to do is, to display a 3D Object immediately after app init (works now, with your help, thank you) but then when the Marker is visible, i want only the 2D Rotation to take effect an moy 3D Object?

For somthing like that, i’m sure, some of the NyARDoubleMatrix34 must be null, the others must be the ones from the marker?

Have you ever done anything like this? It must be a 3D Object, no change with 2D!
Thank you so much for your realy fast and helpfull answer.

@omer — hm…you could hold a marker up in front of the camera while recording the values of the transform Matrix (FLARMarker.transformMatrix), then manually create a Matrix with those values and apply it to your 3d object on app init. that should work, no?

Display a DisplayObject3D without Marker!

Hey ericsoco, have you an idea, how i can achieve that.

I hope you understand wat i’m trying to do. When the camera starts up, there should be immediately the Image or anything i want to be displayed.

I hope anyone here can help me, i’m working on that for so long now!

I think my problem is that i dont realy understand the FlarCamer3D, how can DisplayObjetc3D translated in such a Camera?

Is there anywhere an example of something like that? A link, source code? Anything would help, thank you!!

hello,
i solved my problem about the error-message, when no camera is attached.

i find a bug in your code:
in your FLARCameraSource.as initCamera-methode:

if (!this.attemptedCameras || this.attemptedCameras.length != Camera.names.length) { // if no cameras attempted yet, start with default camera this.attemptedCameras = new Vector.(Camera.names.length, true); this.camera = Camera.getCamera(); // the if is added, because, when there is no camera attached, this.camera == null if (this.camera) { this.attemptedCameras[this.camera.index] = true; } }

with this one added “if” my error-message will displayed.
