How do you convert from an Euler angle to a quateriongreenspun.com : LUSENET : quaternions : One Thread
I just need a top level example of how quaternions work. If, for example, I have an object that I want to rotate 16 degrees about the body's Y axis and 5 degrees about the body's x axis, how do I do this in terms of a quaterion?

There is no universal convention for the way people write 3x3 rotation matrices (few books define it the same way). The definition of a quaternion defined as a matrix has stayed stable with Hamilton's formulation. A great place to learn about the two ways of approaching rotations is in the following paper:
