world_to_local_coordinates

compas.geometry.world_to_local_coordinates(frame, xyz)[source]

Convert global coordinates to local coordinates.

Parameters

  • frame (Frame or [point, xaxis, yaxis]) – The local coordinate system.

  • xyz (array-like) – The global coordinates of the points to convert.

Returns

list of list of float – The coordinates of the given points in the local coordinate system.

Examples

>>> from compas.geometry import Point, Frame
>>> f = Frame([0, 1, 0], [3, 4, 1], [1, 5, 9])
>>> xyz = [Point(2, 3, 5)]
>>> Point(*world_to_local_coordinates(f, xyz)[0])
Point(3.726, 4.088, 1.550)
