Hey all, I'm trying to make your standard, fly anywhere debug Camera in DirectX and have gotten a bit stuck. Essentially, all I want the Camera to do is be rotatable and then move in the direction it's facing. I was trying to implement the rotation part by rotating the eye vector around but I now have an interesting issue when rotating the Camera all the way around. I can't really explain it, so instead I made a video of it and uploaded it. All I am doing in that video is holding the button to rotate the Camera left. The code for rotating the Camera is shown below:

void Camera::rotateCamera(const D3DXVECTOR3 &rot)
{
	D3DXMATRIX rotMat;
	D3DXMatrixRotationYawPitchRoll(&rotMat, rot.x, rot.y, rot.z);
	D3DXVec3TransformCoord(&m_at, &m_at, &rotMat);

	m_cameraMoved = true;
}

As ever, any help is appreciated.

if i were you i would begin with camera from scratch. this might help.

You would have thought so wouldn't you, but I'm passing in 0.01f in the X component of the vector, looks like my Yaw and Pitch got messed up somehow.

Thanks for that article MassacrerAL, the one you linked to was for Managed DirectX but I found the DirectX 9 one and took a look at that. It's a really nice description of how to setup a Camera.
