Class TrajectorySequenceRotation3D

  • public class TrajectorySequenceRotation3D
extends TrajectoryRotation3D
    Combines a number of trajectories.

    Takes an arbitrary number of trajectories and combines them. The start time of the first
    trajectory determines the start time of the union. The remaining trajectories are appended
    discardless of their start time. The duration of the union corresponds to the sum of the
    duration of all the trajectories.

    The value returned in the transition between two trajectories, corresponds to the end point
    of the leading trajectory.

    Access to a value is O(lg n) with n being the number of trajectories combined.

    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      Rotation3D ddx​(double t)
      Acceleration of trajectory at time t

      Returns the acceleration of the trajectory at time t \in[startTime(), endTime()].
      void delete()  
      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.
      Rotation3D dx​(double t)
      Velocity of trajectory at time t

      Returns the velocity of the trajectory at time t \in[startTime(), endTime()].
      static long getCPtr​(TrajectorySequenceRotation3D obj)  
      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.
      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()].

      • duration

        public double duration()
        Description copied from class: TrajectoryRotation3D
        Total duration of the trajectory.

        The duration of the Trajectory corresponds to the time it takes to

      • getIterator

        public TrajectoryIteratorRotation3DPtr getIterator​(double dt)
        Description copied from class: TrajectoryRotation3D
        Returns a bi-directional interator for running through the trajectory.

        For some trajectory types it may be significantly more efficient to run through

        getIterator in class TrajectoryRotation3D
        Parameters:
        dt - [in] The default time step used when using the ++ or -- operators in the
        iterator
        Pointer to the iterator. The pointer has ownership.
