navis.transforms.AffineTransform

class navis.transforms.AffineTransform(matrix, direction='forward')

Affine transformation of 3D spatial data.

Parameters:

matrix ((4, 4) np.ndarray) – Affine matrix.

Examples

A simple scaling transform

>>> from navis import transforms
>>> import numpy as np
>>> M = np.diag([1e3, 1e3, 1e3, 1])
>>> tr = transforms.affine.AffineTransform(M)
>>> points = np.array([[0, 0, 0], [1, 1, 1]])
>>> tr.xform(points)
array([[   0.,    0.,    0.],
       [1000., 1000., 1000.]])

Initialize transform.

__init__(matrix, direction='forward')

Initialize transform.

Methods

__init__(matrix[, direction])	Initialize transform.
append(other)	Append another transform to this one.
check_if_possible([on_error])	Test if running the transform is possible.
copy()	Return copy of transform.
xform(points[, invert])	Apply transform to points.
