Is there a version of RajawaliVuforia for Android versions < 4.0?
Rajawali project was compatible with Android 2.3 until tag v0.9.

hi,
i am trying to use a plane with texture ,
but plane is seems to above marker at some height , despite setting any position value, it remains floating at some height .
if in same manner i am using a md2 model it shows fine on (0,0,0).

Hey Dennis, i tried this project ported and not really working :)

I think QCAR isnt imported correctly

HI, I use rajawali for 3d engine for my AR sdk. i just use openCV function nativeDetect to detect the marker, and get two MAT variables Rvec,Tvec. but I don't know to how calculate the right modelViewmatrix for rajawali engine. i just found a function foundFrameMarker(int markerId, float[] modelViewMatrix) in RajwaliVuforia. and my question is how to get the modelViewMatrix in RajawaliVuforia?

i am trying to implement picking and dragging of 3d model(Object3d) in rajawali vuforia using ObjectColorPicker. i am following this tutorial(Rajawali/Rajawali#753) .i want my 3dmodel to move only if i touch the model.if i press my finger anywhere on the screen the 3d model moves irrespective of touch.
am i missing something??
Any help is appreciated

after debugging i found at that method "onObjectPicked" of ObjectColorPicker is called if i place my finger anywhere on the screen.

code:
Activity:

            @Override
            public boolean onTouchEvent(MotionEvent event) {
                 switch (event.getAction()) {
                     case MotionEvent.ACTION_DOWN:
                              mRenderer.getObjectAt(event.getX(), event.getY());                
                              break;
                     case MotionEvent.ACTION_MOVE:
                              mRenderer.Move(event.getX(),event.getY());
                              break;
                     case MotionEvent.ACTION_UP:
                             mRenderer.stopMovingSelectedObject();
                             break;
                     default:break;
                  }
              }

In Renderer class:

      mPicker = new ObjectColorPicker(this);
     mPicker.registerObject(mF22);
     mPicker.setOnObjectPickedListener(new OnObjectPickedListener() {
        @Override
        public void onObjectPicked(Object3D object3D) {
            mSelectedObject = object3D;
            Log.e(TAG,"selected obj s picked");
        }
    });

Hi everybody

Although RajawaliVuforia's "readme.md" mentions both "Cylinder target" and "Multi-targets" as supported, the actual code doesn't reflect none of them.

As a first step towards rigid-body recognition (prior to impresive but "watermarked" Vuforia 4.0 solution), I'm very interested to know if both functionalities are planned to be implemented.

Best regards.

How does images work. U have used stone image, can i make some custom?

Custom Marker

I'm trying to get this to run on my Samsung GS2. Could you give me the Rajawali version that you are using? I see that's it's a bit older, do you have an update that works on the latest? I've also tried 3 prior versions just to see if I could get one to compile but no luck.

The errors using the latest Rajawali seem pretty trivial, BaseObject3D is no longer and it looks like the parsers being used are no longer there as well. I tried changing the two parsers (MD5 Anim and Mesh) to their corresponding Loader which will compile but when run it runs the screen is black.

I detected a new issue, for some 3d models, example md2, that are loaded in Y negative axis, you need to sale it with Y=-1 to see it right. but when you put the orientation to this kind of objects that are in negative scale, the rotation gets wrong results. I debugged this into the library, and found the wrong result in method Object3d.render()->calculateModelMatrix(parentMatrix);

in this method Object3D i found:
mMMatrix.identity().translate(mPosition).scale(mScale).multiply(mRotationMatrix);
when mScale contains a negative value, gets wrong directions.

i think this can be solved changing the loaded axis, to not modify the operations, because this works fine when are positive scales. i want to avoid the negative scales, but objects are loaded in y axis inverted.

has anyone an idea how to fix it?

I am new to RajawaliVuforia. i am working on ImageTargets. i am trying to implement drag operation on 3d model(Object3D). i have followed this tutorial Rajawali/Rajawali#753 .3d model is moving but it doesn't stick to the ImageMarker("Stones"). it looks like floating in the air.
is there a way to make 3d model stick to ImageMarker when drag operation is performed ??

Now, the latest version of vuforia is 4-2-3.
Can I upgrade project by override Vuforia.jar and libVufoia.so in libs and src/main/libs folder

Hi, I'm having the same issue as issue #9
( #9 )

I have 2 ImageTrackers and I want to see both models when I have both markers. But when one appears the other dissapears.

Perhaps something to do with this? https://developer.vuforia.com/resources/dev-guide/detecting-and-tracking-multiple-targets-simultaneously

Thanks!

Loading an OBJ and doing setRot* or any RotationAnimation in Vuforia applies the wrong rotation, with an error dependent on the camera angle.

Hi,

I'm trying to display the below 3d model in rajawalivuforia example, but the model texture is not applied.

I have replaced g into o in obj file, but still it is not displaying the texture

also i removed following lines from mtl file

map_d //removed
refl //removed
map_kS //removed
map_Ns //removed

Model : https://gist.github.com/hsemar/b55c4fb4d90065344285

Can you please tell me the issue in the model

New bird to android studio. When I sync and import example project to android studio, build action leads to an error like:
failed to resolve : 'org.rajawali3d.vuforia:rajawalivuforia:1.0.0-SNAPSHOT'

I understand that RajawaliVuforiaExamples -> RajawaliVuforia --> Rajawali

is gradle goes online to find the dependencies? could I add the jars and dependencies like before( things like in eclipse days)

Thanks!

Does vufaria implementation supports object picking?
I tried color picker it works when touch on objects. but when touching on spaces other than object it behaves as random object picked. Raypicker always gives a null object as picked.

Recently I moved to Android studio from Eclipse So am not good with it. Can some one please guide me on how to build Rajawali vuforia project on Android studio?
Here's what I tried till now,

1. Cloned the project
2. run gradle.bat with "clean assembleRelease uploadArchives" from command prompt.
3. I get the following error
   ' FAILURE: Build failed with an exception.

What went wrong:
A problem occurred configuring project ':rajawalivuforia'.

SDK location not found. Define location with sdk.dir in the local.properties f
ile or with an ANDROID_HOME environment variable.
'

4. I checked the android sdk path in sdk.dir which is correct sdk.dir=C:\Users\Nilesh\AppData\Local\Android\sdk

I don't know what to do now. Shall I import the project directly in to Android studio as gradle project? but in that case it shows error gradle version is not supported

Hi Dennis
Rajawai and it's integration with Vuforia has been heaven-sent! Thank you for your contribution.
I have an issue trying to animate models such as rotation, translate, color, etc when a marker or image has been found by the Vuforia AR engine.

I saw this stackoverflow thread:
http://stackoverflow.com/questions/17548861/rajawali-and-vuforia-3d-model-positioning

I tried following your suggestion by creating an empty object3d object. However, it appears that by adding my model as a child to it, it follows the same locking trap that is going on for each frame being rendered. Specifically it looks like it's trying to do the animation only that it's looping back over and over.

Do you have any simple script for the initScene and foundImageMarker methods so that I can do the simple animation to it's completion without interference? I hope this makes sense.

Thanks!

I have been attempting to drag the models. but this only works when the camera is looking down on the target and only in one orientation.
I tried to use the method in Rajawali/Rajawali#753
But it also only works for a certain view.
How do i know what the screen touch coordinates correspond to with respect to rajawali coordinates so i can set the position of my moved model.

hi, it seems to be very simple , but i am not able to achieve, i want multiple models to be placed on marker,
suppose four models at corner and one at center etc..

but when i try to tweak the setposition() after the setting of vector3 from vuforia, model position get disturbed and it moves randomly.
plz guide how to achieve this.

thanks in advance!

What I'm trying to do is rotate a md5 model (with a playing animation) around the middle of my scene (really just above the middle of my scene where a have another object). This is my current code and it works just fine as long as you look from above, because as soon as I start to rotate the camera around the object starts rotating sideways (because z axis of the object is changing with the camera).

Animation3D anim = new RotateAnimation3D(Axis.Z, 360);
anim.setDuration(10000);
anim.setRepeatMode(RepeatMode.INFINITE);
anim.setTransformable3D(mDummy);
registerAnimation(anim);
anim.play();

So I guess you can say the code is working as intended but I don't know how to code so that the object rotates around the same point no matter the camera angle.

I know the animation system recently, 8-9april got a bit revamped and I still haven't started using the new codebase but if guys can help me with the old methods displayed here or the new ones I would really appriciate it!

I imported an obj model with textures defined in an mtl file in Rajawali.
I would love to be able to do a fade animation much in the same way with ColorAnimation controlling the color and alpha channels.

Is there a way to do this with png texture imported models?
Is there any technique at all to fade a png textured model manipulating the alpha channels the same way with color? I was able to make some head-way manipulating the RGB values with setMaterialColor but it doesn't seem to accomplish anything with alpha.

When I run my app for the first time on any device, everything runs ok .. the app start and works perfectly, but if I exit my app and run it again I get this ERROR:

FATAL EXCEPTION: GLThread 15673
java.lang.RuntimeException: OpenGL Error: invalid value 1281

at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1516)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240)

this is my onDrawFrame function:

public void onDrawFrame(GL10 glUnused) {
super.onDrawFrame(glUnused);
}

So, what I am trying appears to be simple. I want to add a SkeletalAnimationObject3D to an Object3D, so that i can change the angle and the position independent of the marker. The thing is, when I do that, only a part of the SkeletalAnimationObject3D appears.

Has anyone encountered this bug or knows how to avoid it?

Hi,
I finally found some time to get back to trying this. The former issue I had, with unexplained building errors, was fixed after I looked at alenko's case (#3), and changed the order of the build paths. So, now I get no errors in building - but when I run it, I get exceptions, the same ones as described by alenko, actually. Is there any other changes I should make, perhaps to the RajawaliVuforiaExample build path?

Thanks.

Hi,
Can you somebody please show how to integrate Rajawali with Cloud reco sample in Vuforia?

Hi,

My project is using Rajawali Vuforia. How can i get the target id of the image uploaded on cloud programmatically.

Vuforia example shows using TargetSearchResult to get the "Unique target id".

Hi,

I want to use UserImageTarget funtionality of vuforia with rajwali. Your integrate provides cloud recognition of predefined markers. Please Help me.

Thank You.

Hi,

I have followed the RajawaliVuforia tutorial and integrated the rajawali with vuforia CloudReco and i am able to get the 3D model but model is not aligned/positioned properly in target image center and also if i move camera close or up, the model is positioning out of the target image. Can you please let me know what could be the issue.

Thanks & Regards,
Prakash V

Hello everyone, I am new to the forum, I can through Vuforia, create a vision of a set of POIs, like the nokia city lens?

just an observation, do not want to be told how to do, just wish aber if it is possible to do this with Vuforia or whether it is better to seek another api, if possible can you give me a direction?

I apologize for my language, I'm Brazilian.

Hi,
QCar is not recognized by the IDE. I think some jar is missing. Can you please check it out?

Upgrade Vuforia from 2.8.8 to 3.0.9. Deliberately not upgrading to 4 because of watermarks and license changes.

I have two image targets and the corresponding models for the targets. But the renderer
only shows one or the other. How to display em both if both targets are recognised?

        enemy[0].setPosition(position.x,position.y,position.z);
        sLight1.setPosition(position.x,position.y-5,position.z+5);
        sLight1.setDirection(position);
        enemy[0].setOrientation(orientation);
    }

    if(trackableName.equals("SerraAngel"))
    {
        enemy[1].setVisible(true);
        enemy[1].setPosition(position);
        sLight2.setDirection(position);
        enemy[1].setOrientation(orientation);
    }

}

Is there any possibility in getting the camera object, just to turn on the flashlight of the device?

Some code snippet would be nice,
of course i found some discussions about getting it via jni, but this failed due to no support in the vuforia SDK.

Is there a way that works nowadays?

I want the camera feed displayed with a transparent web view over it so that I can load content to the web view using JavaScript.

My aim is to replicate the exact behavior of Layar & Metaio did.

Hey there,
first of all I want to thank you for your work on rajawali and on this bridge with vuforia, which I was lately trying to protoype on.

Everything ran fine until I pulled the last changes to both the Rajawali and the RajawaliVuforia repos.
Now whenever I launch any of my RajawaliVuforia-dependant projects I get a crash on initialization, here is a snippet of the logs :

If I run the example found in the master folder it runs perfectly !!! WHY ?

I imported an obj model with textures defined in an mtl file in Rajawali.
I would love to be able to do a fade animation much in the same way with ColorAnimation controlling the color and alpha channels.

Is there a way to do this with png texture imported models?

i am trying t implement object picking in your vuforia project , i followed :

Is there any way to access the camera image from within the java code?

For my project I have to analyze the image taken by the camera and I only found a workaround to make a preview view with 1x1px in the corner, but this isn't a great solution. And I would like to use the image taken by Rajawali then making another camera instance.

Thank you for your effort and I'm looking forward to your answer.

I just wanted to try RajawaliVuforia, but I can't get it to work.
Apparently the dependency to Rajawali is based on their master branch rather than the 0.9 release? That's just asking for trouble...

From what I understand, Rajawali was recently switched to Android Studio, but RajawaliVuforia is still an eclipse project.
How can I use them together now?
Are you planning on porting it to studio soon too?

I have the example running. The camera view looks fine until I scan the 001 vuforia marker and I get the following segfault. Has anyone seen this before? I can also bring this dump over to vuforia and see if they can help although this environment is probably not one they have much experience in.

So I now have the example app running. I assume the the two markers being used, with ids of 1 and 2 correspond to the pngs located in the Vuforia SDK called:
frameMarker_000.png
frameMarker_001.png

I've enlarged these pngs and have given them a red background. I bring that up on my monitor, aim my phone at it and I am not seeing foundFrameMarker() being called. Any ideas?

This will be a recurring issue as long as vuforia gets some updates.

Vuforia 2.6.10 has just been released, so I'd suggest you integrate it also in this repo for the new features.

https://developer.vuforia.com/resources/sdk/android

Is there any possibility to load marker from SD card? Now I only see method createImageMarker, which require xml to be placed in assets folder. How can I make my app load targets from any location?

hi ,
could you please suggest the change to make your vuforiaRajawali sample to run in portrait mode , because when i changes the orientation of app the matrix seems to mismatch and 3d model(fighter plane) moves randomly when i move marker.

plz post a solution to run this Vuforia+Rajawali sample to run in portrait mode.
thanks in advance!!
