Euler Angles

There are many conventions for how to define Euler angles, based on choices of which of the x,y,z axis to use in what order and whether the rotation axis is in the body frame (and hence affected by previous rotations) or in in a fixed frame. See http://en.wikipedia.org/wiki/Conversion_between_quaternions_and_Euler_angles for a general description.

  • All Euler angles are specified in radians.
  • The names are all rotation_from_{fixed/body}_abc() where abc is the ordering of x,y,z.

Note
The first rotation is by an angle about the z-axis. The second rotation is by an angle about the new y-axis. The third rotation is by an angle about the new z-axis.
Parameters
[in]RotFirst Euler angle (radians) defining the rotation (Z axis)
[in]TiltSecond Euler angle (radians) defining the rotation (Y axis)
[in]PsiThird Euler angle (radians) defining the rotation (Z axis)
