Inside FLARManager: Loading Collada Models
<– Basic Augmented Reality | Customization –>
“Proto is so cute. I want one!”
well, here’s how you do it.
This tutorial will run you through the basics of getting an augmented reality application with a Collada model up and running. This tutorial is almost identical to the basic augmented reality tutorial. You might want to try that one first, or even the 2D tutorial. Or, you might just want to dive right in.
FLARManager Tutorial: Augmented Reality with Collada models
Download source for this tutorial here:
FLARManagerTutorial_Collada
and place it in the root of the /src/ FLARManager folder.
Print out any of the ‘pattNNN.png’ markers in this folder to use with the tutorial.
This tutorial will demonstrate how to draw an animated model wherever FLARToolkit sees a marker. (Big thanks to Tom Tallian for the Scout model!) We’ll start with just one model for now; things get more complex when you want to support multiple models tied to multiple markers.
First, we create a FLARManager instance, passing in the path to an external xml configuration file. For now, we’ll use flarConfig.xml (located in the /resources/ folder in the FLARManager download).
this.flarManager = new FLARManager("../resources/flar/flarConfig.xml");
Once you’re comfortable with the basics of FLARManager, you can edit this config file, or create your own, as you see fit. More information on configuration options lives here.
We want to see the video capture, so let’s add it to the stage. FLARManager creates a default video source all ready to go, though the source can also be modified via the configuration file.
this.addChild(Sprite(this.flarManager.flarSource));
FLARManager uses an event model to notify any interested parties of newly-detected markers, changes in already-detected markers, and marker removal. We add FLARMarkerEvent handlers to respond to these changes.
this.flarManager.addEventListener(FLARMarkerEvent.MARKER_ADDED, this.onMarkerAdded);
this.flarManager.addEventListener(FLARMarkerEvent.MARKER_UPDATED, this.onMarkerUpdated);
this.flarManager.addEventListener(FLARMarkerEvent.MARKER_REMOVED, this.onMarkerRemoved);
We’ll write our event handlers in just a a bit. First, we wait for FLARManager to initialize before setting up the Papervision3D environment.
this.flarManager.addEventListener(Event.INIT, this.onFlarManagerInited);
Setting up Papervision3D
once FLARManager has finished initializing, we can set up the Papervision3D environment:
private function onFlarManagerInited (evt:Event) :void {
this.flarManager.removeEventListener(Event.INIT, this.onFlarManagerInited);
this.scene3D = new Scene3D();
// initialize FLARCamera3D with parsed camera parameters.
this.camera3D = new FLARCamera3D(this.flarManager.cameraParams);
this.viewport3D = new Viewport3D(this.stage.stageWidth, this.stage.stageHeight);
this.addChild(this.viewport3D);
// flip display to match mirrored source
this.viewport3D.x = this.stage.stageWidth;
this.viewport3D.scaleX = -1;
this.renderEngine = new LazyRenderEngine(this.scene3D, this.camera3D, this.viewport3D);
this.pointLight3D = new PointLight3D();
this.pointLight3D.x = 1000;
this.pointLight3D.y = 1000;
this.pointLight3D.z = -1000;
this.addEventListener(Event.ENTER_FRAME, this.onEnterFrame);
Papervision has to re-render the scene every frame, so we add an ENTER_FRAME event handler in which we’ll do that. (We’ll get to that part in a sec.)
FLARToolkit camera parameters
This section is extra credit, but thought you might want to know about that FLARCamera3D line…
FLARToolkit compensates for distortion caused by the camera lens by referring to an external camera parameters file. In the FLARToolkit download, this is named ‘camera_para.dat’; in FLARManager, the file is named ‘FLARCameraParams.dat’. FLARToolkit creates a special FLARCamera3D object (that subclasses Papervision3D’s Camera3D) that incorporates this correction into Papervision3D’s display.
FLARCamera3D requires the information from the camera parameters file, but FLARManager cannot provide this until it has loaded and parsed this file. Therefore, we wait to initialize the Papervision3D environment until after FLARManager has initialized. Once there, we pass the parsed camera parameters data (stored in a FLARParam instance) to the new FLARCamera3D.
Create the Model
Let’s set up a single DAE instance that we’ll map to the detected marker. The DAE class, in the ASCollada library, provides a simple framework for loading and displaying Collada models in Flash applications.
// load the model.
// (this model has to be scaled and rotated to fit the marker; every model is different.)
var model:DAE = new DAE(true, “model”, true);
model.load(”../resources/assets/scout.dae”);
model.rotationX = 90;
model.rotationZ = 90;
model.scale = 0.5;
// create a container for the cube, that will accept matrix transformations.
this.modelContainer = new DisplayObject3D();
this.modelContainer.addChild(model);
this.modelContainer.visible = false;
this.scene3D.addChild(this.modelContainer);
var model:DAE = new DAE(true, "model", true);
model.load("../resources/assets/scout.dae");
model.rotationX = 90;
model.rotationZ = 90;
model.scale = 0.5;
// create a container for the model, that will accept matrix transformations.
this.modelContainer = new DisplayObject3D();
this.modelContainer.addChild(model);
this.modelContainer.visible = false;
this.scene3D.addChild(this.modelContainer);
We place the DAE inside of a DisplayObject3D so that we can position the DAE as needed to match the scene. This particular model needs to be rotated and scaled to align with the marker. If we applied the transformation matrix directly to the DAE instance, the rotation and scale would be overwritten, and the model would not display correctly.
Responding to FLARMarkerEvents
Now that FLARManager and Papervision3D are both set up, we can make the two work together by drawing Papervision3D objects when handling FLARMarkerEvents coming from FLARManager.
private function onMarkerAdded (evt:FLARMarkerEvent) :void {
this.modelContainer.visible = true;
this.activeMarker = evt.marker;
}
private function onMarkerRemoved (evt:FLARMarkerEvent) :void {
this.modelContainer.visible = false;
this.activeMarker = null;
}
For the purposes of this tutorial, we’re simply toggling the visibility of the model as a marker is added and removed from the camera’s view. We’re also keeping track of the active FLARMarker, from which we’ll extract and apply the transformation matrix that makes the model appear to be tethered to the marker.
For more on FLARMarkerEvents, see the 2D tutorial.
Updating the Model
As mentioned earlier, Papervision has to re-render the scene every frame. We’ll take advantage of this opportunity to apply the latest transformation matrix to the model, to make it look like it’s Augmenting our Reality.
private function onEnterFrame (evt:Event) :void {
this.modelContainer.transform = FLARPVGeomUtils.convertFLARMatrixToPVMatrix(this.activeMarker.transformMatrix);
this.renderEngine.render();
}
Note that the FLARMarker instance we’re tracking as this.activeMarker will be updating itself continuously; FLARManager handles this for us. We could listen for changes as MARKER_UPDATED events, but since we have to render the Papervision scene every frame, we can just grab the updated information from this.activeMarker while we’re at it.
You might also notice that long, ugly method call, FLARPVGeomUtils.convertFLARMatrixToPVMatrix. (Unfortunately at times like this, I’m a firm believer in self-commenting code.) FLARToolkit uses a different coordinate system than Papervision (and Flash 3D, and Away3D, and Sandy, and Alternativa), so we have to convert FLARToolkit’s transformation matrix into numbers that make sense to Papervision before applying the matrix to the model. Coincidentally, FLARPVGeomUtils has just the method for us!
That should take care of it — you should now see a red-shirted fella perched gently on the marker in your hand!
To handle multiple models and multiple markers, we have to be smarter about managing all the DisplayObject3D instances and active FLARMarker instances. One way to do this (though with simple cubes, not Collada models) is laid out in this example:
FLARManagerExample_PV3D
Note that this gets fairly sticky fairly quickly, as models take much longer to load than simple cubes, and also consume more processing power to animate. A good multi-model application will use low-poly-count models, load each model on-demand, and be sure not to load models more than once per session.
Also, FLARManager supports arbitrary aspect ratios. No need to stick with 4:3! Here’s a 16:9 example, if you want to get all cinematic:

Hi, I am having strange problem with basically every AR application
AdamH | 2009/08/23 | 9:10 amHi,
I am having strange problem with basically every AR application created with flarmanager.
I can import a collada model with animation and textures and it works perfectly.
I am creating my appz with no problem by clicking on Run application. My html and swf object is stored in bin-debug and it works fine. But If i will move those files to different location, it will not work at all. I am not getting the picture from webcamera (camera is allowed in swf file in browser).
So I tried “Export release build”, that will export everything to folder bin-release, but swf file is smaller immediately and there is not possible to see any picture from camera at all.
I am bit confused from that. I would like to upload my AR test online, but it just do not work.
I am sorry for my probably lame question – I am not a programmer, I am 3d designer.
Any thoughts how I can sort that out? Thanks in advance for any help

ericsoco | 2009/08/23 | 4:52 pm@AdamH: this is not really a FLARManager issue, it’s a more general issue than that. i suggest you start with more basic tutorials on building flash projects, from a site like flashkit or ultrashock or kirupa. one possibility, however, is that you’re getting a sandbox error when trying to load the config file from outside of the Flex Builder debugger. go to this site:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html
and make sure the path you’re running your swf/html file from is included in the list. if it’s not, add it.
thank you very much for help. will look at it.

AdamH | 2009/08/24 | 3:36 amTo be honest, I took a look on the sites you suggested but it is really hard to find information I particulary need.
I used to do some basic animations in flash few years back, but never application.
The sandbox error is sorted out very quickly thru settings of Flash Manager. but that solves problem only for me, not for the others. If I will publish my files online no one can see them.
It is last issue which I have.
I can create 3d models, export them to .dae, sort out texture problems, run it locally, but still I do not know how I can publish it on the internet.
Can you please give me another hint?
I am sorry for probably stupid question, but I really do not want to get into as3/flash/flex problematique > I would like to present my 3d low poly models easily and Flart with FlarManager looks like good way to me.
problem solved... Yesterday at night I forgot to download debug

You mentioned that multiple collada models can be used instead
Steven | 2009/10/21 | 7:35 amYou mentioned that multiple collada models can be used instead of the simple cubes, can you give me a little hint on how this can be done? For example you would use this line of code: return new FlatShadeMaterial(this.pointLight3D, 0xCCCCCC, 0×666666); to change the color/material of the cube but instead I want to grab a collada model. Any hint on how to do this would be great help.
Thank you

ericsoco | 2009/10/21 | 10:20 am@steven — take a look at FLARManagerTutorial_Collada for an example of loading a collada file. basic strategy is to create a list of collada files, and display them when their corresponding patterns are detected.

Thank You for replying to my comment !
I installed the LiveHTTPHeaders plugin for firefox and launched it but it is empty.
Here’s a screen grab:
http://www.UploadScreenshot.com/image/44764/4906998
It is blank with both Firefox and IE.
I reinstalled Flarmanager and Flex Builder but still the same.
Could it be a collision between flash player 9 and 10 ? I uninstalled flash player 9 and installed flash player 10 and the debugger for it.
After that the program still told me that the current version of flash player is not able to debug my application and that i should download a debugger for Flash Player 9. Then after downloading and reinstalling the debugger again for FP10 the error was gone but now there is a blank page without any errors.
I tried to clean the project, nothing happened.
Can you help me with this problem ?

I can implement the dae file and it shows up perfectly. The dae model follows the marker if I move it in up/down motion. Th only problem I can’t figure out is when I move the marker to the right of the screen, the dae model moves to the left of the screen. So the dae model does not follow the marker horizontally, it moves in the opposite direction of the marker.
Any thoughts or help on this please?

Mahesh | 2010/02/07 | 10:23 pmHi everybody!
Could anyone please tell me that how should i place a model(3D Display object which does not associated with any marker) right after the last marker ?. I have tried x,y and z coordinates of last marker to map my model next to it but it does not help me. Please give me a solution as soon as possible. I have been dying for it last two days.
Note : I am using flar manager for multiple marker.
Thanks for the clear easy break down of everything. Curious

Curious if you have any resource links for loading in animated 3D models. I read so much about the problems between exporting animated collada files from Blender, have you read anything or can you share anything? Better applications to use than Blender? Anything helps.
Thanks again.
@micah, your best bet is the forum for the 3D

Thanks for the fast response. Seems like Papervision seems to
Micah | 2010/02/18 | 3:42 pmThanks for the fast response. Seems like Papervision seems to be standard, but would you recommend any over any else?

Wietse | 2010/02/25 | 6:40 pm@thomas – on 2010/01/11 you posted that you managed to display multiple models with multiple marker’s. I was wondering if you can help me in the right direction here or if you can post (some) of your code.
I’m new to this and I’m having a very hard time figuring out how to do this.
Any help would be greatly appreciated!
Thank you in advance.
@ericsoco - Hi Eric. Great work with this tutorial. I
Wietse | 2010/02/26 | 9:40 pm@ericsoco – Hi Eric. Great work with this tutorial. I can really understand how it all works thanks to your descriptions. I just have one question, you mentioned at the top that things will get more complicated when using multiple markers and multiple models. Do you have a tutorial for that somewhere?
Would love to create that but it is very hard to figure out how.
Thanks so much.
@wietse -- nope, sorry. best i can offer is
ericsoco | 2010/02/27 | 12:44 pm@wietse — nope, sorry. best i can offer is FLARManagerExample_3D, which creates a different-colored cube for each pattern. the trick with multiple models ends up being about loading/managing your assets. search the FLARToolkit forum for more answers; this thread comes up often.
@wietse: it's not that. Just follow the tutorial with the
thomas | 2010/03/02 | 1:52 pm@wietse: it’s not that. Just follow the tutorial with the multiple colored cubes and combine it whith this one (about loading collada models).
In the colored cubes tutorial, you’ll notice that there’s a function that retrieves a color from an id, and then puts it in a materialslist. If you just change that function into loading collada models, instead of returning a color… Well then there you have it, multiple markers with multiple models. Here’s what I mean in code:
private function getModelByPatternId(patternId:int):DAE
{
var model:DAE=new DAE(true, “model”);
switch (patternId)
{
case 0:
model.load(”model.dae”);
return model;
case 1:
model.load(”model2.dae”);
return model;
}
}
get it?
Hi Thomas, Where do I post this code? If i post
Lucas | 2010/03/09 | 11:21 amHi Thomas,
Where do I post this code?
If i post into SimpleCubes_PV3d.as, and use this example, i get this error: Id 1046: Type was not found or was not a compile-time constant: DAE. FLARManager/src/examples/support SimpleCubes_PV3D.as line 141
In line 141: private function getModelByPatternId(patternId:int)

Thaks in advance. And thanks ericsoso for the answers and for the FLARManager.
Sorry about my english…
