Method Summary

Modifier and Type	Method	Description
boolean	epsilonEquals(O other, double epsilonCoordinate, double epsilonDirection)	Compare this Oriented with another Oriented with specified tolerances in the coordinates and the angles.
double	getDirZ()	Return the rotation around the z-axis in radians.
O	neg()	Return a new Oriented with negated coordinate values.

Method Detail

neg

O neg()

Return a new Oriented with negated coordinate values. Adds 180 degrees (pi radians) to the rotation(s).

Returns:

D; a new Oriented with negated coordinate values and a rotation in the opposite direction

getDirZ

double getDirZ()

Return the rotation around the z-axis in radians.

Returns:

double; the rotation around the z-axis in radians

epsilonEquals

boolean epsilonEquals(O other,
                      double epsilonCoordinate,
                      double epsilonDirection)
               throws NullPointerException,
                      IllegalArgumentException

Compare this Oriented with another Oriented with specified tolerances in the coordinates and the angles.

Parameters:

other - O; 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 other is null

IllegalArgumentException - epsilonCoordinate or epsilonRotation is NaN or negative
