libpysal.cg.get_ray_segment_intersect¶

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

Returns the intersection of a ray and line segment.

Parameters:

raylibpysal.cg.Ray: A ray to check for an intersection.
seglibpysal.cg.LineSegment: A segment to check for an intersection against ray.

Returns:

intersection{libpysal.cg.Point, libpysal.cg.LineSegment, None}: The intersecting point or line between ray and seg if an intersection exists or None if ray and seg do not intersect.

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)
