I fixed the error.
Not sure why it failed, but the solution has been deleted from the cache the cparam_cache.db file.

Thanks for the help

I could see an object. I drew in the z -400 point . In the smartphone it is drawn at the point 0 ...
But it is very strange because the 3D object is a child of trackableObject but follows the camera , not the trackableObject ... In the smartphone works well .

smartphone: getPosition = (0.0, 0.0 , -20.02002) getDirection = (0.0021968328,-0.004591274,-0.9999871)

tablet:  getPosition = (0.0, 0.0, -20.02002) getDirection = (0.0.-1.1897111E-7,-1.0)

I think yes, they are physically on the screen.
I've done it from getTransformedCenter ().
Approximately:
Tablet : ( 8f , -7F , -37f )
Smartphone ( 28f 12f -450f )
The values ​​change when I move the camera.

the value of z is suspicious right?

The tablet is Samsung Galaxy Tab 3 GT-P5210 10.1"

My code extends a library https://github.com/plattysoft/ArToolKitJpctBaseLib

The library integrates jpct with ARToolKit .

My main class extends ArJpctActivity:

public class MainClass extends ArJpctActivity

https://github.com/plattysoft/ArToolKitJpctBaseLib/blob/master/ArJpctBaseLib/src/main/java/org/artoolkit/ar/jpct/ArJpctActivity.java

The ArJpctActivity extends ArActivity and creates the render
https://github.com/plattysoft/ArToolKitJpctBaseLib/blob/master/ArJpctBaseLib/src/main/java/org/artoolkit/ar/base/ARActivity.java

ArJpctRender extends ArRender
https://github.com/plattysoft/ArToolKitJpctBaseLib/blob/master/ArJpctBaseLib/src/main/java/org/artoolkit/ar/jpct/ArJcptRenderer.java

ARRender
https://github.com/plattysoft/ArToolKitJpctBaseLib/blob/master/ArJpctBaseLib/src/main/java/org/artoolkit/ar/base/rendering/ARRenderer.java



The main problem is that the code works perfectly on the smartphone but not on the tablet.

Objects are created correctly ( I think).

Hello,
I made an application that draws several 3d models following a marker ARToolKit .
My problem is that in a 4.5-inch smartphone works perfectly, but the same code in a 10-inch tablet does not draw 3D objects on the screen.
Notes:
- The 3D objects are compiled well .
- Once it worked by chance on the tablet.
-The Marker detects Well, that's not a problem.

Smartphone 4.5 inch:


Tablet 10 inch: t shows nothing


What do you think?

Solved !
I spent many hours but I finally got what I wanted.
Draw several 3D objects on a ARToolKit(Android) marker and then click on each of them.

Thanks for the help

Hello,

I found an adaptation of ARToolKit + jpct + android:

https://github.com/plattysoft/ArToolKitJpctBaseLib

I've got draw various 3D objects on the screen.
But now I have the problem: I need to touch them
I saw this tutorial: http://www.jpct.net/wiki/index.php?title=Picking
But my class is something different, is very abstracted and simple and I'm a newbie ..

This is the mainClass, I don't found my framebuffer...

            astronaut[0].setOrigin(new SimpleVector(0, 0, 270));

            return  astronaut[0];
        }


        This method doesnt work
        public boolean onTouchEvent(MotionEvent me) {
            if (me.getAction() == MotionEvent.ACTION_DOWN) {
                Toast.makeText(this, cubo.getXAxis().toString()+" "+String.valueOf(me.getX()),2000).show();

                return true;
            }
              ....
}
