Angular Velocity Magnitude (WM)
Returns the magnitude of the difference between the angular velocity vectors of two coordinate system markers.
Format
WM (To Marker, From Marker)
Arguments
To Marker | (Required) The coordinate system marker whose angular velocity is being measured. |
From Marker | (Optional) The coordinate system marker whose angular velocity is subtracted off. If not specified, this argument defaults to the global coordinate system. |
Equation
Mathematically, WM is calculated as follows:
where:
■
is the angular velocity vector of the To Marker, T, with respect to the ground reference frame, G.
is the angular velocity vector of the To Marker, T, with respect to the ground reference frame, G.■
is the angular velocity vector of the From Marker, F, with respect to the ground reference frame, G.
is the angular velocity vector of the From Marker, F, with respect to the ground reference frame, G.Example
The following example returns the magnitude of the angular velocity vector between marker_T and marker_F:
WM(marker_T, marker_F)
