ngawari 0.1.21

A simple and functional toolkit for working with data in VTK.

Ngawari

Ngawari is a Python-based toolkit for simplifying operations in data analysis and processing, particularly focused on medical imaging and computational geometry. It is built heavily on top of the VTK library.

Features

• Advanced geometric calculations and transformations
• Medical imaging data processing
• Statistical analysis tools
• 3D visualization capabilities

Installation

To install Ngawari, run the following command:

pip install ngawari

Usage

Here's a quick example of how to use Ngawari:

from ngawari import ftk, fIO, vtkfilters
import numpy as np

# Create a simple sphere
sphere = vtkfilters.buildSphereSource([0, 0, 0], radius=1.0)

# Get points as numpy array
points = vtkfilters.getPtsAsNumpy(sphere)

# Add a scalar array
vtkfilters.setArrayFromNumpy(sphere, points[:, 0], "x_coords", SET_SCALAR=True)

# Apply a filter
smoothed = vtkfilters.smoothTris(sphere, iterations=10)

# Write to file
fIO.writeVTKFile(smoothed, "smoothed_sphere.vtp")

# Build image over sphere:
image = vtkfilters.buildRawImageDataFromPolyData(smoothed, res=[0.1,0.1,0.1])

# Add a scalar array to the image
vtkfilters.setArrayFromNumpy(image, np.random.rand(image.GetNumberOfPoints()), "random_scalar", SET_SCALAR=True)

# Null scalars outside sphere
image_nulled = vtkfilters.filterNullOutsideSurface(image, smoothed)

# Write to file
fIO.writeVTKFile(image_nulled, "image_over_sphere.vti")
