intersection_segment_polyline
- compas.geometry.intersection_segment_polyline(segment, polyline, tol=None)[source]
Calculate the intersection point of a segment and a polyline.
- Parameters:
- segment[point, point] |
compas.geometry.Line XYZ coordinates of two points defining a line segment.
- polylinesequence[point] |
compas.geometry.Polyline XYZ coordinates of the points of the polyline.
- tolfloat, optional
Tolerance value for computing the intersection points between the segment and the polyline segments. Default is
TOL.absolute.
- segment[point, point] |
- Returns:
- [float, float, float] | None
The intersection point or None if the segment does not intersect with any of the polyline segments.
Examples
>>> from compas.geometry import is_point_on_polyline >>> from compas.geometry import is_point_on_segment >>> from compas.geometry import distance_point_point >>> from compas.geometry import centroid_points >>> p = [(0.0, 0.0, 0.0), (1.0, 0.0, 0.5), (2.0, 0.5, 1.0)] >>> s = [(0.5, 0.0, 0.0), (0.5, 0.0, 2.0)] >>> x1, x2 = intersection_segment_polyline(s, p) >>> x = centroid_points([x1, x2])
>>> is_point_on_polyline(x, p) True
>>> is_point_on_segment(x, s) True
>>> distance_point_point((0.5, 0.0, 0.25), x) < 1e-6 True
