The ACCZ function returns the z-axis acceleration of one marker or the z-axis relative acceleration 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 marker for axis definition • If omitted, then the InertiaMarker is applied. |
Marker4 |
A standard marker for calculating acceleration • The formula calculates acceleration relative to the angular velocity and the angular acceleration of Marker4. • Marker4 must be the same value as Marker3. If omitted, then the InertiaMarker is applied. |
Formulation
: Acceleration vector of Marker1 relative to the angular velocity and angular acceleration of Marker4
: Acceleration vector of Marker2 relative to the angular velocity and angular acceleration of Marker4
: z-direction unit vector of Marker3
