Dear Biomech-l subscribers,
I am using Helical Axes of Motion (HAM) to describe motion of bones. I
have multiple HAM vectors with rotations about each vector in space. These
vectors are not coincident and therefore I am not sure how find a single
HAM vector in space that is an average of all the individual vectors and
rotations.
Secondly, if I have a single HAM vector with a rotation about this vector,
is there a way to break this vector into components so that we can show how
much rotation is about the x, y, and z axes.
If anyone has references or suggestions about how to solve these questions,
please send them to my email address.
Thank you,
