obliqueslice

A Python package for slicing 3D numpy arrays along an oblique plane. Equivalent to obliqueslice in MATLAB.

Installation

pip install obliqueslice

Usage

import numpy as np
from obliqueslice import obliqueslice

# Create a 3D volume
volume = np.random.rand(100, 100, 100)

# Define a point and normal vector for the slice
point = [50, 50, 50]  # Point on the plane (x, y, z)
normal = [1, 1, 1]    # Normal vector to the plane

# Extract the oblique slice
slice_img, slice_u, slice_v, coords_3D = obliqueslice(volume, point, normal)

Parameters

• V: 3D numpy array with shape (rows, cols, depths) indexed as (y, x, z)
• point: Point on the plane in world coordinates (x, y, z)
• normal: Normal vector to the plane
• method: Interpolation method ('linear' or 'nearest', default: 'linear')
• threshold: Threshold for cropping out the 'black' parts of the plane
• fill_value: Value to use for points outside the volume (default: 0)
• interp_order: Interpolation order (default: None, auto-determined from method)

Returns

• slice_img: The extracted 2D slice
• slice_u: U coordinates of the slice grid
• slice_v: V coordinates of the slice grid
• coords_3D: 3D coordinates for every point in the slice

Requirements

• numpy
• scipy
