world_to_local_coordinates

compas.geometry.world_to_local_coordinates(frame, xyz)

Convert global coordinates to local coordinates.

Parameters:

frame[point, vector, vector] | compas.geometry.Frame

The local coordinate system.

xyzarray-like[[float, float, float] | compas.geometry.Point]

The global coordinates of the points to convert.

Returns:

list[[float, float, 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)
