Translation
-
class
compas.geometry.
Translation
(matrix=None)[source] Bases:
compas.geometry.transformations.transformation.Transformation
Create a translation transformation.
- Parameters
matrix (4x4 matrix-like, optional) – A 4x4 matrix (or similar) representing a translation.
- 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
