Line

class compas.geometry.Line(p1, p2, **kwargs)[source]

Bases: Primitive

A line is defined by two points.

Parameters

p1 ([float, float, float] | compas.geometry.Point) – The first point.
p2 ([float, float, float] | compas.geometry.Point) – The second point.

Attributes

start (compas.geometry.Point) – The start point of the line.
end (compas.geometry.Point) – The end point of the line.
vector (compas.geometry.Vector, read-only) – A vector pointing from start to end.
length (float, read-only) – The length of the vector from start to end.
direction (compas.geometry.Vector, read-only) – A unit vector pointing from start and end.
midpoint (compas.geometry.Point, read-only) – The midpoint between start and end.

Examples

>>> line = Line([0, 0, 0], [1, 1, 1])
>>> line
Line(Point(0.000, 0.000, 0.000), Point(1.000, 1.000, 1.000))
>>> line.start
Point(0.000, 0.000, 0.000)
>>> line.midpoint
Point(0.500, 0.500, 0.500)
>>> line.length == math.sqrt(1 + 1 + 1)
True
>>> line.direction
Vector(0.577, 0.577, 0.577)
