  • Method Summary

    Modifier and Type
    Method
    Description
    boolean
    epsilonEquals(D other, double epsilonCoordinate, double epsilonDirection)
    Compare this Directed with another Directed with specified tolerances in the coordinates and the angles.
    D
    neg()
    Return a new O with negated coordinate values.

  • Method Details

    • neg

      D neg()
      Return a new O with negated coordinate values. Adds 180 degrees (pi radians) to the rotation(s).
      Returns:
      D; a new D with negated coordinate values and a rotation in the opposite direction

    • epsilonEquals

      boolean epsilonEquals(D other, double epsilonCoordinate, double epsilonDirection) throws NullPointerException, IllegalArgumentException
      Compare this Directed with another Directed with specified tolerances in the coordinates and the angles.
      Parameters:
      other - D; the point to compare with
      epsilonCoordinate - double; the upper bound of difference for one of the coordinates; use Double.POSITIVE_INFINITY if you do not want to check the coordinates
      epsilonDirection - double; the upper bound of difference for the direction(s); use Double.POSITIVE_INFINITY if you do not want to check the angles
      Returns:
      boolean; true if x, y, and z are less than epsilonCoordinate apart, and rotX, rotY and rotZ are less than epsilonRotation apart, otherwise false
      Throws:
      NullPointerException - when point is null
      IllegalArgumentException - epsilonCoordinate or epsilonRotation is NaN or negative
