A cylindrical joint allows both rotation and translation based on the z- axis of marker. It has one rotational degree of freedom at the direction of z-axis and one translational degree of freedom along the z-axis. It can be located anywhere along the axis about which the parts can rotate or slide with respect to each other. The orientation of the cylindrical joint defines the direction of the axis about which the parts can rotate or slide along with respect to each other. The rotational axis of the cylindrical joint is parallel to the orientation vector. It passes through the location.
