Support / Re: Odd behavior of the translation
« on: January 26, 2011, 11:29:33 pm »
Yes you are correct, I'm viewing them from the top. And I think the 45° rotation of the primitive might explains my problem. When turning the cubes by 45° in my mind and then also turn the camera by 45° it should be correct. Is there a way to create a cube without the pre-rotation?
I now rotate the cube when creating it (and before translating it) , but this feels a bit off. Or is it the best way to deal with the Problem? And it looks odd as well.
This is the camera setting:
@Second post:
No there shouldn't be any relations and I create them all in a LinkedList. Thank you for the example, I will have a look at it!

Support / Odd behavior of the translation

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:
Then I overrided the constructor:
In onSurfaceChanged I add the 4 fields to the scene:
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:
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.
Code: [Select]
public class Field extends com.threed.jpct.Object3DThen I overrided the constructor:
Code: [Select]
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:
Code: [Select]
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.

The System.out reads like this, which should be the correct translations:
Code: [Select]
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.

Thanks for the answer but DDMS isn't working right. (It starts with an exception and won't show any data while the emulator is running) I believe you, that DDMS is more useful and I will try to get it running, but right now I could fix my problem just with the logfile.
Doesn't anybody know where it is?

Support / Logger-file location (Newbe question)
« on: January 25, 2011, 11:44:00 am »
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
