The ROLL function expression calculates the third angle (in radians) of a 3-2-1 Euler rotation sequence between Marker1 and Marker2.
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 x-axis, which is the third rotation.
Example
ROLL (body1.Marker1)
ROLL (body1.Marker1, body2.Marker2)
ROLL (1,2) <Argument: (1)body1.Marker1, (2)body2.Marker2 >
