Problems with 10-inch tablet
« on: June 28, 2016, 10:54:06 pm »

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?

You are you creating the GL setup/context? Is that done by the ARToolKit or in your app?

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:

Code: [Select]
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).

Android Monitor:
Code: [Select]

Have you checked if your objects are physically there where you expect them to be? Object3D.getTransformedCenter() might help here. Are the results similar to those on the phone?

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?

It might be...it depends on the location and view direction of the camera. Can you post Camera.getPosition() and Camera.getDirection() as 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)

Looks reasonable. On both devices, the camera points into the direction of the negative z-axis, which is where your objects are located as well. The -470 seems strange when comparing it to the phone's values, but it shouldn't prevent the objects from being visible...unless you've adjusted the far clipping plane. It would try to place some object in front of the camera by hand to see if it's a rendering issue (which I doubt) or an issue with object placement.

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 .

It has to have something to do with the AR code. jPCT-AE by itself doesn't distinguish between different devices.

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
