quat2euler Convert quaternion to Euler angles (azimuth/elevation/tilt or heading/attitude/bank or yaw/pitch/roll). NOTE: there is a loss of information in the conversion from quaternion to Euler angles. This behaviour is matched by the original Shoemake algorithm.	from the library : quat Format : External Environment : max freeware Max 4.6 http://www.mat.ucsb.edu/~wakefield/soft/ http://www.mat.ucsb.edu/~wakefield/soft/quat_release.zip
