Hi,
I want to drag an object3D , I follow the wiki about how to object it's works but when I try to move the object with the translate method, the object isn't under the mouse

my code :
public void mouseMoved(MouseEvent me) {
if(picked==null) return;
dest =Interact2D.reproject2D3DWS(world.getCamera(), buffer, me.getX(), me.getY());
System.out.println(dir.calcSub(dest).toString() + " " + me.getX() + " " + me.getY());
dest.z = 0;
dir.z = 0;
moveObj3D(picked, dir.calcSub(dest));
dir = dest;
}
How can I fix it ?
Thanks for your help.
