Projection
- class compas.geometry.Projection(matrix=None)[source]
Bases:
compas.geometry.transformations.transformation.Transformation
Create a projection transformation.
- Parameters
matrix (4x4 matrix-like, optional) – A 4x4 matrix (or similar) representing a projection transformation.
- Raises
ValueError – If the default constructor is used, and the provided transformation matrix is not a shear matrix.
