      Specified by:
      createStep in class TTrack
      Parameters:
      n - the frame number
      x - the x coordinate in image space
      y - the y coordinate in image space
      Returns:
      the new step

    • createStep

      public Step createStep(int n, double x, double y, double xc, double yc)
      Creates a vector step with specified tail position and vector components.
      Parameters:
      n - the frame number
      x - the tail x coordinate in image space
      y - the tail y coordinate in image space
      xc - the x component in image space
      yc - the y component in image space
      Returns:
      the new step
