Binding a camera to a body (once more ;))

I know this topic was brought up some time ago, but since the new version of NxOgre has come, some things has changed.

Simply, I have a body with a sphere shape and I'd like to bind a camera to it. The problem is that the camera attached directly to the body's node is rotating in the same way as my moving ball. If the body was a character there wouldn't be any problem with it, but I couldn't get my ball rolling. How can I solve this?

You could do two things:

1. Don't bind the Camera to the Sphere, Just copy the position of the Sphere to the Camera.

2. Bind the Camera and freeze the rotational movement of the Sphere.

Yup, the first way is the best for me, thanks. Geez.. I wish I had thought about it earlier.

OK I've got the camera rotating around my ball using getGlobalPosition(). However there happen weird things while moving the ball. If I add a force to it, the camera immediately is getting a great speed in the same direction as I forced the ball but the speed is disproportionately high. There are also some unexpected rotations of the camera node..
Note: The mBallPos value is updated each frame.

void PlayCam::update(Ogre::Real timeElapsed)
{
Vector3 mBallPos = Global->mBall->getBallPos(); // get the updated ball position
Vector3 mCamPos = mCamNode->getPosition();

const MouseState &ms = Global->mMouse->getMouseState();

float RotX = ms.Y.rel * -mRotateScale;
float RotY = ms.X.rel * -mRotateScale;

Quaternion rotateQuaternionCam = mCamera->getOrientation();
rotateQuaternionCam.normalise();
Vector3 CamAxisX = rotateQuaternionCam.xAxis();
CamAxisX.normalise();

Quaternion rotateQuaternionCamX( rotateQuaternionCam.getPitch(false), CamAxisX );

Quaternion rotateQuaternionX(Degree(RotX), CamAxisX);
Quaternion rotateQuaternionY(Degree(RotY), Vector3::UNIT_Y);

Vector3 targetPos = Vector3(mBallPos.x,0,mBallPos.z);

mCamNode->setPosition(targetPos + rotateQuaternionX*rotateQuaternionY * mCamPos);
mCamera->lookAt(targetPos);
}

EDIT: Aww what a shame.. The camera position was set wrong. More sleep, less coffee..
