libpysal.cg.get_ray_segment_intersect(ray, seg)[source]¶

Returns the intersection of a ray and line segment.

Parameters:¶

ray : libpysal.cg.Ray¶

A ray to check for an intersection.

seg : libpysal.cg.LineSegment¶

A segment to check for an intersection against ray.

Returns:¶

intersection – The intersecting point or line between ray and seg if an intersection exists or None if ray and seg do not intersect.

Return type:¶

{libpysal.cg.Point, libpysal.cg.LineSegment, None}

Examples

>>> ray = Ray(Point((0, 0)), Point((0, 1)))
>>> seg = LineSegment(Point((-1, 10)), Point((1, 10)))
>>> i = get_ray_segment_intersect(ray, seg)
>>> isinstance(i, Point)
True

>>> str(i)
'(0.0, 10.0)'

>>> seg2 = LineSegment(Point((10, 10)), Point((10, 11)))
>>> get_ray_segment_intersect(ray, seg2)
