Method Detail

getPlaneOfTheHorizonOrientation

public static void getPlaneOfTheHorizonOrientation(Cartesian c,
                                                   float[] orientation)

Return the orientation of the plane of the horizon (based on the DefaultConvention) for the argument Cartesian coordinate

Parameters:

c - the Cartesian coordinate at which to calculate the orientation of the plane of the horizon

orientation - the float array to initialize with the axis angle orientation

getOrientation

public static void getOrientation(Attitude attitude,
                                  float[] orientation)

Return the axis angle representation that cooresponds to the argument Attitude object

Parameters:

attitude - the Attitude object to convert

orientation - the float array to initialize with the axis angle orientation

getOrientation

public static void getOrientation(Quaternion quat,
                                  float[] orientation)

Return the axis angle representation that cooresponds to the argument Quaternion object

Parameters:

quat - the Quaternion object to convert

orientation - the float array to initialize with the axis angle orientation
