did you set object.setCollisionMode(Object3D.COLLISION_CHECK_OTHERS); ?

yes, exactly Sandy Bridge.
Thank you for advice!

I just bought new laptop, and wanna add ssd for speed increasing.
Egon, what do you think about OCZ VERTEX 3? Or about Plextor  devices?

Well, i think  this is a new phase in android progress. And make sense for third party manufactures go further, and making more qualitative products. i mean hardware.

Yes, just read in wiki about it.
http://www.jpct.net/wiki/index.php/Picking
Here is little example:
Code: [Select]
SimpleVector dir = Interact2D.reproject2D3DWS(cam, fb, x, y)
.normalize();
Object[] res = world.calcMinDistanceAndObject3D(cam.getPosition(), dir,
distProjection);

Yes, i know, and i'm doing it right now. But i don't now the orentation of the object in  the world.
So, at the moment i dont' know about which axish i must rotate object.
And for detection of orientation in the world i'm trying to use normalls, but they are returns some magic not normalls results(

Ok, i'll try to explain...
i have some object, and after picking it, i want to rotate it. Rotation can be in 4 directions - left, right, up, down.
For example:
i rotete object twice: to the left and to the right, rotation was around Y axis.
Then i rotate object up, and  aafter i want to rotate it to the left. If i'll rotate it around y axis , that wil be wrong rotation, You agree?

What exactly, my task?) Or my  decision? :)

Hm, but with the normals vectors i,m tring to determine object position and orientation in world...
For it's rotation after picking, etc.
So , i thought use for this task unit vector, i mean polygon normals.
Maybe this task has another decision?

Well, actually i confused about this values:
8.3051646E-7 or -4.371139E-8 or -6.357829E-8....

Hi!
In your demo example, i'm trying to rotate object adround Y Axis like this:
Code: [Select]
public static final float NINETY_DEGREES = 1.570796327f;
        .....

if (touchTurn != 0) {
cube.rotateY(NINETY_DEGREES);
touchTurn = 0;
}

and trying to get nomall vector of polygon, which i'm picking:
Code: [Select]

@Override
public void collision(CollisionEvent ce) {

ce.getTargets();
int[] ids = ce.getPolygonIDs();;
for (int i = 0; i < ids.length; i++){
Logger.log("poligon id is" + ids[i]);
}
Logger.log("name of picked object are " + this.getName());
TextureBox box = (TextureBox)ce.getObject();
if (box != null){
Logger.log("Normalized X Axis" + box.getXAxis().normalize().toString());
Logger.log("Normalized Y Axis" + box.getYAxis().normalize().toString());
Logger.log("Normalized Z Axis" + box.getZAxis().normalize().toString());

Logger.log("getTransformedNormals" + box.getPolygonManager().getTransformedNormal(ids[0]).toString());


}


}

so, i have only 4 direction when i'm rotating my cube. But i reciving a lot of different values when i try getAxis, and getTranformedNormall.  Only at the first time i'm getting correct values. And i'm confused in this when i'm facing this problem.
Example:
Code: [Select]
1:
I/jPCT-AE ( 6221): Normalized X Axis(1.0,0.0,0.0)
I/jPCT-AE ( 6221): Normalized Y Axis(0.0,1.0,0.0)
I/jPCT-AE ( 6221): Normalized Z Axis(0.0,0.0,1.0)
I/jPCT-AE ( 6221): getTransformedNormals(-0.0,-0.0,-1.0)

2:
I/jPCT-AE ( 6221): Normalized X Axis(8.3051646E-7,0.0,1.0)
I/jPCT-AE ( 6221): Normalized Y Axis(0.0,1.0,-0.0)
I/jPCT-AE ( 6221): Normalized Z Axis(-1.0,0.0,8.3051646E-7)
I/jPCT-AE ( 6221): getTransformedNormals(-8.2651775E-7,-0.0,-1.0)

3:
I/jPCT-AE ( 6221): Normalized X Axis(-4.371139E-8,0.0,-1.0)
I/jPCT-AE ( 6221): Normalized Y Axis(0.0,1.0,-0.0)
I/jPCT-AE ( 6221): Normalized Z Axis(1.0,0.0,-4.371139E-8)
I/jPCT-AE ( 6221): getTransformedNormals(-6.357829E-8,-0.0,-1.0)
4:
I/jPCT-AE ( 6221): Normalized X Axis(-1.4424753E-6,0.0,-1.0)
I/jPCT-AE ( 6221): Normalized Y Axis(0.0,1.0,0.0)
I/jPCT-AE ( 6221): Normalized Z Axis(1.0,0.0,-1.4424753E-6)
I/jPCT-AE ( 6221): getTransformedNormals(-1.4623007E-6,-0.0,-1.0)
5:
I/jPCT-AE ( 6221): Normalized X Axis(-1.0,0.0,1.1364959E-6)
I/jPCT-AE ( 6221): Normalized Y Axis(-0.0,1.0,0.0)
I/jPCT-AE ( 6221): Normalized Z Axis(-1.1364959E-6,0.0,-1.0)
