Reflection

class compas.geometry.Reflection(matrix=None)[source]

Bases: Transformation

Class representing a reflection transformation.

A reflection transformation mirrors points at a plane.

Parameters

matrix (list[list[float]], optional) – A 4x4 matrix (or similar) representing a reflection.

Examples

>>> point = [1, 1, 1]
>>> normal = [0, 0, 1]
>>> R1 = Reflection.from_plane((point, normal))
>>> R2 = Transformation([[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, -1, 2], [0, 0, 0, 1]])
>>> R1 == R2
True
