Hi everyone,

I am trying integrate jpct ae with wikitude AR. I already look at the tutorial integrate artoolkit with jpct ae as reference. But i have problem that object 3D not stay in marker.  Here is my code so far:

  public void onDrawFrame(GL10 gl) {
               if (_wikitudeRenderExtension != null) {
                _wikitudeRenderExtension.onDrawFrame(gl);
                }

              if (_currentlyRecognizedTarget != null) {
                world.removeAllObjects();

                float[] projectionCamera = _currentlyRecognizedTarget.getProjectionMatrix();
                projMatrix.setIdentity();
                projMatrix.setDump(projectionCamera);
                projMatrix.transformToGL();
                SimpleVector translation=projMatrix.getTranslation();
                SimpleVector dir=projMatrix.getZAxis();
                SimpleVector up = projMatrix.getXAxis();
                cam.setPosition(translation);
                cam.setOrientation(dir, up);


                markerMatrix.setIdentity();
                float[] marker1Transformation= _currentlyRecognizedTarget.getViewMatrix();
                markerMatrix.setDump(marker1Transformation);
                markerMatrix.transformToGL();
                cube.clearTranslation();
                cube.setRotationMatrix(markerMatrix);
                cube.setTranslationMatrix(markerMatrix);
               // cam.setBack(markerMatrix);
                world.addObject(cube);
                world.renderScene(fb);
                world.draw(fb);
                fb.display();


Please kindly assist. Thank you

Hai, i have 3ds file and when i render it with jpct-ae i can see the object not render perfectly.. this my code:

                world = new World();
world.setAmbientLight(30, 30, 30);
sun = new Light(world);
sun.setIntensity(255, 255, 255);
// Create a texture out of the icon...:-)
TextureManager txtMgr = TextureManager.getInstance();
if (!txtMgr.containsTexture("BURJ_AL_.JPG")) {
Texture texture = new Texture(BitmapHelper.rescale(
BitmapHelper.convert(mActivity.getResources().getDrawable(R.drawable.burj_al_arab_map)), 512, 512));
txtMgr.addTexture("BURJ_AL_.JPG", texture);
}

Context mContext =mActivity.getApplicationContext();
InputStream stream = null;
try {
stream = mContext.getAssets().open("burj_al_arab.3DS");

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//cube = Primitives.getCylinder(20, 80);
cube=Loader.load3DS(stream, 1f)[0];
cube.setCulling(false);
cube.strip();
cube.build();
world.addObject(cube);

I attach pic of screen shot.

hai, i have collada file that contains animation. i tried load using ardorCollada2bones.bat but show error unable to load collada resource. thank you

Hai, when i want to rotate i got confused..how the concept of rotating?

Hai, i try to render primitive plane , but it is not showing. But if i render primitive box or cylinder it  just fine. 

plane = Primitives.getPlane(20, 30);
plane.setTexture("texture");
plane.strip();
plane.build();
world.addObject(plane);
cam = world.getCamera();
SimpleVector sv = new SimpleVector();
sv.set(plane.getTransformedCenter());
sv.y += 100;
sv.z += 100;

sun.setPosition(sv);

MemoryHelper.compact();


Thank you

hai, i want to change texture in plane when i click button. how to do it? thank you

In my app, am using JPCT-ae for 3d rendering. I am downloading 3d models form server and rendering it in android device. my problem is some models are small and some are very big. I want to set one generic scale for all the models regardless of what scale they were exported with. so that when i render them on device they should be of same size.

I dont know to do it. please any idea any help is very much appreciated.
