Hi Eric,

thanks for the tutorial. I’m newbie.

I’ve download flarmanager. I tried to compile FLARManagerTutorial_3D.as, but I get some error, I guess it comes from

import flash.display.Sprite;
import flash.events.Event;

because of the source that I downloaded did not have the flash package. where I can get the package? how to solve this problem?

btw, I also did not find

package “transmote.utils.time.FramerateDisplay”, which this package is used in some examples

thanks

also, i created a plane with 80×80 that should be exactly at the position of the marker, but it isn´t and it´s higher than the marker, but same width…

var wMat:WireframeMaterial = new WireframeMaterial(0xFFFFFF, 1, 1);
var plane:Plane = new Plane(wMat, 80, 80);
this.mainContainer.addChild(plane);

it works fine, but i have a problem with the transformation. using the tutorial source except those lines:

this.viewport3D.x = this.stage.stageWidth;
this.viewport3D.scaleX = -1;

…and everything set to 320×240 (swf, flarmanager-xml). but whenever i create something at the origin (0,0,0) it is moved 10-20 pixels in y-direction. i created a plane with 80×80, it is exactly as big as the marker but the coordinates are wrong…

Thanks for the tutorials, they are great.
I have a question though, I’m trying to change the size of the cubes depending on the pattern id, like it does with the colours, but I not sure what to replace in the code. Could you put me in the right direction?
Cheers.

Compiled wth FLash CS4 makes me tones of error messages:

1044: Interface method labeling in namespace org.libspark.flartoolkit.core.labeling:IFLARLabeling not implemented by class org.libspark.flartoolkit.core.labeling:FLARLabeling_BitmapData.

I’ve made a planeContainer = new DisplayObject3D() and i applied the transform to it.

I’ll try to rotate it and make it doublesided too. Thanks for the advices

@ Tollis — did you try replacing the cube with a plane, without modifying anything else? so you still don’t apply the transform to the plane, you apply it to the plane’s parent object (in the example, cubeContainer). also, planes are a little trickier because materials are one-sided; either set your material.doublesided = true, or set your plane.rotationX or rotationY to 180 to flip the plane around so it’s facing the camera. (note that rotation gets overwritten when you apply a transform matrix, which is why i put the cube into a container and apply the transform matrix to the container.)

Thanks for the great tool you gave us Eric.

I have a problem though. The example above works fine with cube. My problem is that i cant display a simple Plane. I make a new DisplayObject3D, I add my plane object in it and then i add my DisplayObject3D to scene3D.

Then in the EnterFrame function i write

this.plane.transform = FLARPVGeomUtils.convertFLARMatrixToPVMatrix(this.activeMarker.transformMatrix);

crapola. moved the example files around recently, didn’t notice they would break these links. thx for catching that, @cpp. fixed.

Hi, just so you know, there are a few links to tutorials and examples giving 404 errors:
