local_to_world_coordinates_numpy

compas.geometry.local_to_world_coordinates_numpy(frame, rst)[source]

Convert local coordinates to global (world) coordinates.

Parameters

• frame ([point, vector, vector] | compas.geometry.Frame) – The local coordinate system.

• rst (array-like[[float, float, float] | compas.geometry.Point]) – The coordinates of the points wrt the local coordinate system.

Returns

(N, 3) ndarray – The world coordinates of the given points.

Notes

origin and uvw together form the frame of local coordinates.

Examples

>>> from compas.geometry import Point, Frame
>>> frame = Frame([0, 1, 0], [3, 4, 1], [1, 5, 9])
>>> rst = [Point(3.726, 4.088, 1.550)]
>>> xyz = local_to_world_coordinates_numpy(frame, rst)
>>> np.allclose(xyz, [[2.000, 3.000, 5.000]], rtol=1e-3)
True
