Distance Magnitude (DM)
Returns the magnitude of the translational displacement vector from one coordinate system marker to another.
Format
DM (To Marker, From Marker)
Arguments
To Marker | (Required) Coordinate system marker to which the distance is measured. |
From Marker | (Optional) Coordinate system marker from which the distance is measured. If not specified, this argument defaults to the global coordinate system. |
Equation
Mathematically, DM is calculated as follows:
where:
■
is the position vector from the global origin to the To Marker, T.
is the position vector from the global origin to the To Marker, T.■
is the position vector from the global origin to the From Marker, F.
is the position vector from the global origin to the From Marker, F.Example
The following function returns a number greater than or equal to 0:
Function | DM(marker_T, marker_F) |
Result | 13 |
