Hello. Check out this site: http://www.cs.berkeley.edu/~laura/cs184/quat/quaternion.html It will give you a good idea about quaternions in general (ie the math behind it and the meaning of the 4 elements). Note: this site is not at all related with Java, but it helped me a lot in understanding what I'm doing and what I can do. You will see in this site that every matrix (in this case the rotational part of your transform) can be converted to a quaternion and vice versa. I hope this answers your question.
