- class Transformation(translation: ndarray[Any, dtype[float64]], scale: ndarray[Any, dtype[float64]], rotation: ndarray[Any, dtype[float64]], affine_matrix: ndarray[Any, dtype[float64]])[source]
Transformation data class to store the translation, scale, rotation, and the composed affine matrix.
For the reference of the transformation matrix, see https://en.wikipedia.org/wiki/Transformation_matrix.
- translation
The length-3 translation vector.
- Type:
numpy.ndarray[Any, numpy.dtype[numpy.float64]]
- scale
The length-3 scaling vector, which is the scaling factor along each axis.
- Type:
numpy.ndarray[Any, numpy.dtype[numpy.float64]]
- rotation
The 3x3 rotation matrix.
- Type:
numpy.ndarray[Any, numpy.dtype[numpy.float64]]
- affine_matrix
The 4x4 affine matrix composed of the translation, scaling, and rotation.
- Type:
numpy.ndarray[Any, numpy.dtype[numpy.float64]]
