Hai, i have to change texture when user click a button. How to change texture in runtime? i try add texture to texture manager and setTexture in onDrawFrame, but it not working, have error out of memory. Thank you.

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

yes..i have and still it likes transparent..
It seems that white color texture is become transparent..
in my 3d max screenshoot the roof of Burj al arab white.. but when i render it becomes transparent

 3d artist said it maybe flip surface when i render it in jpct-ae. how to fix flip surface of texture?

it should like this in 3d max ..in my previous pic, texture like transparent (sorry i have difficult in english so i can't explain it in detail). As you can see it different between 3dMax and in my phone...

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.

as you suggest i use OgreMax plugin, and now may file have ext format .scene . How to use it? in many tutorial they use .xml

well, i will try that way..Thank you

Would you try to load the 3d file? may be my 3d file has error or something.. Can i send my file to you?

my friend create it in 3d max.. and i export it to  dae. I am using Autodesk 3ds Max design 2009.

Here is the error .

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?

Hi Egon,
plane.setTransparency(100); but i still see black border line.how to make that border line invisible?

Thank you Egon for the answer it's working.
I setCulling false and  rotate the plane by 180 degress around the x-axis  and yes my plane too huge..i don't know how to calculate it..thanks for information
