distance_line_line
- compas.geometry.distance_line_line(l1, l2, tol=0.0)[source]
Compute the shortest distance between two lines.
- Parameters
l1 ([point, point] |
compas.geometry.Line) – Two points defining a line.l2 ([point, point] |
compas.geometry.Line) – Two points defining a line.
- Returns
float – The distance between the two lines.
Notes
The distance is the absolute value of the dot product of a unit vector that is perpendicular to the two lines, and the vector between two points on the lines (1, 2).
If each of the lines is defined by two points (\(l_1 = (\mathbf{x_1}, \mathbf{x_2})\), \(l_2 = (\mathbf{x_3}, \mathbf{x_4})\)), then the unit vector that is perpendicular to both lines is…
