が、わかりにくいですし、説明もしづらい。。。values[0]: Azimuth, rotation around the Z axis (0<=azimuth<360). 0 = North, 90 = East, 180 = South, 270 = West
values[1]: Pitch, rotation around X axis (-180<=pitch<=180), with positive values when the z-axis moves toward the y-axis.
values[2]: Roll, rotation around Y axis (-90<=roll<=90), with positive values when the z-axis moves toward the x-axis.
と思っていたら、わかりやすい説明を見つけました。
