Shear
- class compas.geometry.Shear(matrix=None, check=True)[source]
Bases:
Transformation
Class representing a shear transformation.
A point P is transformed by the shear matrix into P” such that the vector P-P” is parallel to the direction vector and its extent is given by the angle of P-P’-P”, where P’ is the orthogonal projection of P onto the shear plane.
- Parameters
matrix (list[list[float]], optional) – A 4x4 matrix (or similar) representing a shear transformation.
- Raises
ValueError – If the default constructor is used, and the provided transformation matrix is not a shear matrix.
