The WZ function returns one marker’s z-axis angular velocity or the z-axis relative angular velocity between two markers.
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. |
Marker3 |
The name or argument number of the reference marker that will serve as the standard for direction • If omitted, then the InertiaMarker is applied. |
Formulation
: Marker1’s angular velocity vector from the InertiaMarker
: Marker2’s angular velocity vector from the InertiaMarker
: z-direction unit vector of Marker3
