      Dereferencing operator.
      TrajectoryRotation3DCPtr cptr()  
      Rotation3D ddx​(double t)

      The pointer stored in the object.
      double duration()
      Total duration of the trajectory.

      The duration of the Trajectory corresponds to the time it takes to
      run through it.

      If the trajectory is empty, then -1 is returned.

      Returns the velocity of the trajectory at time t \in[startTime(), endTime()].
      double endTime()
      Returns the endTime of the trajectory.

      The end time equals startTime() + duration().

      TrajectoryRotation3D getDeref()
      Member access operator.
      TrajectoryIteratorRotation3DPtr getIterator()
      Returns a bi-directional interator for running through the trajectory.

      For some trajectory types it may be significantly more efficient to run through
      using an iterator, rather than using random access.


      Pointer to the iterator.
      TrajectoryIteratorRotation3DPtr getIterator​(double dt)
      Returns a bi-directional interator for running through the trajectory.

      For some trajectory types it may be significantly more efficient to run through
      using an iterator, rather than using random access.
      SWIGTYPE_p_std__vectorT_rw__math__Rotation3DT_double_t_t getPath​(double dt)
      Constructs a discrete path based on the trajectory.

      If uniform = true the path will be divided into the smallest number of
      uniform steps for which the time stepsize <= dt.

      If uniform = false the path is divided into steps of duration dt, except the
      last interval which may be shorter to include the end point.
      SWIGTYPE_p_std__vectorT_rw__math__Rotation3DT_double_t_t getPath​(double dt, boolean uniform)
      Constructs a discrete path based on the trajectory.

      If uniform = true the path will be divided into the smallest number of
      uniform steps for which the time stepsize <= dt.

      If uniform = false the path is divided into steps of duration dt, except the
      last interval which may be shorter to include the end point.
      boolean isNull()
      checks if the pointer is null
      boolean isShared()
      check if this Ptr has shared ownership or none
      ownership
      double startTime()
      Returns the startTime of the trajectory
      Rotation3D x​(double t)
      Position of trajectory at time t

      Returns the position of the trajectory at time t \in[startTime(), endTime()].
