Spatial

Transform

Contains transforms for spatially manipulating the root system.

This module defines the spatial transforms needed for manipulating the root system using affline transformation matrices.

deeprootgen.spatial.transform.get_transform_matrix(roll: float = 0, pitch: float = 0, yaw: float = 0, translation: list[float] = [0, 0, 0], reflect: list[float] = [1, 1, 1, 1], scale: list[float] = [1, 1, 1, 1]) → ndarray

Updates the transformation matrix.

Args:

roll (float):

Rotation about the x-axis in degrees.

pitch (float):

Rotation about the y-axis in degrees.

yaw (float):

Rotation about the z-axis in degrees.

translation (list[float]):

Translation matrix.

reflect (list[float]):

Reflection matrix.

scale (list[float]):

Scaling matrix.

Returns:

np.ndarray:

Transformation matrix.

deeprootgen.spatial.transform.get_x_rotation_matrix(theta: float) → ndarray

Construct a rotation matrix for the x axis.

Args:

theta (float):

The x rotation angle in degrees.

Returns:

np.ndarray:

The x rotation matrix.

deeprootgen.spatial.transform.get_y_rotation_matrix(theta: float) → ndarray

Construct a rotation matrix for the y axis.

Args:

theta (float):

The y rotation angle in degrees.

Returns:

np.ndarray:

The y rotation matrix.

deeprootgen.spatial.transform.get_z_rotation_matrix(theta: float) → ndarray

Construct a rotation matrix for the z axis.

Args:

theta (float):

The z rotation angle in degrees.

Returns:

np.ndarray:

The z rotation matrix.

deeprootgen.spatial.transform.make_homogenous(arr: array) → ndarray

Adds an additional ‘W’ dimension of ones to the array. Performs a conversion from Cartesian coordinates to homogenous coordinates.

Args:

arr (float):

The array of Cartesian coordinates.

Returns:

np.ndarray:

The homogenous array.
