Since I'm actually about to learn how to use the engine, I tried to order 4 cubes in a pattern shown below in the "intended" image. For doing this I first created an object which extends the Object3D class:
public class Field extends com.threed.jpct.Object3D

Then I overrided the constructor:

public Field(int posX, int posY, Field next){
        super(Primitives.getCube(10));
        setXY(); //<-stuff for the getX / getY functions
matrix.translate(getX()*30,0 , getY()*30);
this.setTranslationMatrix(matrix);
}

In onSurfaceChanged I add the 4 fields to the scene:


for (com.theDiceGame.Field f : fields){
f.strip();
f.build();
System.out.println("Translation: "+f.getTranslation());
world.addObject(f);
}

That seems to work. In the simulator will be 4 cubes visible. But they are not positioned as I intended them to.

How I intended them to be positioned.


How they are positioned

The System.out reads like this, which should be the correct translations:
Translation: (0.0,0.0,0.0)
Translation: (30.0,0.0,0.0)
Translation: (30.0,0.0,30.0)
Translation: (0.0,0.0,30.0)

I also checked the rotation (because It looks like they where rotated by 45° and then translated) but the rotation Matrix is 0 except on the diagonal which should be a zero rotation.

Hello everyone,

since I'm starting to get a bit used to Android I wanted to write a little 3D application. For debugging reasons I need to get some messages which I tried to log.  (like this one: Logger.log("Translation: "+f.getTranslation())

My problem is, I don't know where the logfile is saved. I looked everywhere in my project (since it is not big I finished quickly) and after that looked in the documentation for a possibility to set my own path. Can you tell me where that log-file is located?

Thanks,
gucky
