orient_points

compas.geometry.orient_points(points, reference_plane, target_plane)[source]

Orient points from one plane to another.

Parameters

• points (sequence[[float, float, float] | compas.geometry.Point]s) – XYZ coordinates of the points.

• reference_plane ([point, vector] | compas.geometry.Plane) – Base point and normal defining a reference plane.

• target_plane ([point, vector] | compas.geometry.Plane) – Base point and normal defining a target plane.

Returns

list[[float, float, float]] – XYZ coordinates of the oriented points.

Notes

This function is useful to orient a planar problem in the xy-plane to simplify the calculation (see example).

Examples

>>> from compas.geometry import Point
>>> from compas.geometry import orient_points
>>> from compas.geometry import intersection_segment_segment_xy

>>> refplane = ([0.57735, 0.57735, 0.57735], [1.0, 1.0, 1.0])
>>> tarplane = ([0.0, 0.0, 0.0], [0.0, 0.0, 1.0])
>>> points = [            [0.288675, 0.288675, 1.1547],            [0.866025, 0.866025, 0.0],            [1.077350, 0.077350, 0.57735],            [0.077350, 1.077350, 0.57735]        ]

>>> points = orient_points(points, refplane, tarplane)
>>> ab = points[0], points[1]
>>> cd = points[2], points[3]
>>> point = intersection_segment_segment_xy(ab, cd)
>>> points = orient_points([point], tarplane, refplane)

>>> Point(*points[0])
Point(0.577, 0.577, 0.577)
