Translation

class compas.geometry.Translation(matrix=None, check=True)[source]

Bases: Transformation

Class representing a translation transformation.

Parameters: matrix (list[list[float]], optional) – A 4x4 matrix (or similar) representing a translation.
Attributes: translation_vector (Vector) – The translation vector.
Raises: ValueError – If the default constructor is used, and the provided transformation matrix is not a translation.

Examples

>>> T = Translation.from_vector([1, 2, 3])
>>> T[0, 3] == 1
True
>>> T[1, 3] == 2
True
>>> T[2, 3] == 3
True

>>> from compas.geometry import Vector
>>> T = Translation.from_vector(Vector(1, 2, 3))
>>> T[0, 3] == 1
True
>>> T[1, 3] == 2
True
>>> T[2, 3] == 3
True

>>> T = Translation([[1, 0, 0, 1], [0, 1, 0, 2], [0, 0, 1, 3], [0, 0, 0, 1]])
>>> T[0, 3] == 1
True
>>> T[1, 3] == 2
True
>>> T[2, 3] == 3
True
