Distance Along Y (DY)
Returns a y component of the translational displacement vector from one coordinate system marker to another.
Format
DY (To Marker, From Marker, Along 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. |
Along Marker | (Optional) Coordinate system marker along whose y-axis the distance is measured. |
Note: If not specified, optional arguments default to global coordinate system. | |
Equation
Mathematically, DY 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.■
is the unit vector along the y-axis of the Along Marker, A.
is the unit vector along the y-axis of the Along Marker, A.Example
The following function returns the y component of the displacement vector from marker_F to marker_T, along the y-axis of marker_A:
Function | DY(marker_T, marker_F, marker_A) |
Result | -5 |
