pysdic.PointCloud.to_npz

PointCloud.to_npz(filepath, save_properties=True)

Save the point cloud to a NumPy NPZ file.

The points will be saved as an array named ‘points’ with shape \((N_p, E)\). Additional properties will be saved as separate arrays in the NPZ file with names in the format "_properties/{property_name}".

• from_npz() method for creating a PointCloud object from a NPZ file.

Parameters:

• filepath (str) – The path to the output NPZ file.

• save_properties (bool, optional) – If True, all properties of the point cloud will be saved as separate arrays in the NPZ file. Default is True.

Return type:

None

Examples

Saving a PointCloud object to a NPZ file.

from pysdic import PointCloud
import numpy as np

# Create a random point cloud with 100 points
random_points = np.random.rand(100, 3)  # shape (100, 3)
point_cloud = PointCloud.from_array(random_points)

# Save the point cloud to a NPZ file
point_cloud.to_npz('path/to/output_point_cloud.npz')

This will save the points and properties of the point cloud to the specified NPZ file.
