Method Detail

getAxisAngles

public static double[] getAxisAngles(short xAxisDirection,
                                     short yAxisDirection,
                                     short zAxisDirection)

Parameters:

xAxisDirection -

yAxisDirection -

zAxisDirection -

Returns:

null if non valid entries.

getAxisDirections

public static short[] getAxisDirections(double roll,
                                        double pitch,
