The rotation matrix
R_AB is created based on 3 angles
about new axes (intrinsic) in the order x-y-z.
The angles (called Euler angles or Tait-Bryan angles) are defined by the following
procedure of successive rotations:
Given two arbitrary coordinate frames
B, consider a temporary frame
T that initially coincides with
In order to make
T align with
B, we first rotate
x about its x-axis (common axis for both
T is rotated an angle
y about the NEW y-axis of
Finally, codeT is rotated an angle
z about its NEWEST z-axis.
The final orientation of
T now coincides with the orientation of
The signs of the angles are given by the directions of the axes and the right hand rule.
