Reflection

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

Bases: compas.geometry.transformations.transformation.Transformation

Creates a Reflection that mirrors points at a plane.

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
