validate_transform4x4(

transform: TransformLike,

/,

*,

must_be_finite: bool = True,

name: str = 'Transform',

) → NumpyArray[float]

Validate transform-like input as a 4x4 ndarray.

Parameters:

transformTransformLike

Transformation matrix as a 3x3 or 4x4 array, vtkMatrix3x3 or vtkMatrix4x4, vtkTransform, or a SciPy Rotation instance. If the input is 3x3, the array is padded using a 4x4 identity matrix.

must_be_finitebool, default: True

Check if all elements of the array are finite, that is, not infinity and not Not a Number (NaN).

namestr, default: “Transform”

Variable name to use in the error messages if any of the validation checks fail.

Returns:

np.ndarray

Validated 4x4 transformation matrix.
