comment What is the relationship between various groups
@DonAntonio I am wondering if nxn matrices represent a subgroup of some group of automorphisms besides representing the projective transformations. If that doesn't make any sense, its probably cause I don't know what I am saying :s

comment quaternion to angle
If you are trying to move the character in the direction that the character is facing, there is no need to convert to a quaternion, you can use out vector of the rotation matrix. I would ask the question "How do I move translate a character in the facing direction?" here: gamedev.stackexchange.com . If no one answers the question there, I will.
