The PHI function returns the rotation angle of the third rotation in a z-x-z sequence of Euler angles.
Format
Arguments definition
Marker1 |
The name or argument number of a marker to be calculated. |
Marker2 |
The name or argument number of a marker to be calculated. • If omitted, then the InertiaMarker is applied. |
Formulation
In line with the sequentially defined rotation order, return rotation angle φ on the z-axis, which is the third rotation.
Example
PHI(body1.Marker1)
PHI(body1.Marker1, body2.Marker2)
PHI(1,2) <Argument: (1)body1.Marker1, (2)body2.Marker2 >
