A dual unit vector can be interpreted as a dual quaternion with 0 scalar parts. The 3D rigid transformation that is represented by a unit dual quaternion is easily related to the corresponding screw around a screw axis. As described above, the screw axis is defined by its direction with and ... Webb10 maj 2011 · The helical axis is calculated from the screw axes which link successive base pair reference frames. Each screw transformation defines a vector U passing through a point p . This point can be moved to either base pair reference frame by sliding it along U until the vector from p to the origin of the base pair frame is perpendicular to U . cracked profile picture
