Distance Between Two Skew Lines
To calculate the distance between two skew lines the lines are expressed using vectors,
- .
The cross product of b and d is perpendicular to the lines, as is the unit vector
(if |b × d| is zero the lines are parallel and this method cannot be used). The distance between the lines is then
- .
