DIMOUSESTATE has lX, lY, and lZ members in it (lZ is commonly for the mouse wheel). With a mouse, these members describe the amount of change, not the actual position.

If lX is less than zero, the user is moving their mouse left, and if greater than zero, they are moving their mouse right (IIRC). If lY is less than zero, the user is moving the mouse down, but if it''s greater than zero, it''s being moved up

position.x = (view.x + distance*sinf(rotationY)*sinf(rotationX));position.z = (view.z + distance*cosf(rotationY)*sinf(rotationX));position.y = -(view.y + distance*cosf(rotationX));

This is part of my camera code... position is a vector for the position of the camera. view is a vector for the spot you are looking at with the camera. rotationX/rotationY are their respective changes in mouse movement. Copy and paste at your own risk.
