pysdic.PointCloud.is_finite

PointCloud.is_finite()

Check which points in the point cloud are finite (not NaN or infinite).

This method returns a boolean mask indicating which points in the point cloud are finite.

See also

• all_finite() method for checking if all points are finite.

• is_nan() method for getting a boolean mask of NaN points.

Returns:

A 1D boolean NumPy array of shape \((N_p,)\) where \(N_p\) is the number of points in the point cloud. Each element is True if the corresponding point is finite, and False otherwise.

Return type:

numpy.ndarray

Examples

Create a PointCloud from a NumPy array containing some NaN and infinite values.

import numpy as np
from pysdic import PointCloud

# Create a point cloud with some NaN and infinite values
points = np.array([[0.0, 1.0, 2.0],
                   [np.nan, 1.0, 2.0],
                   [3.0, np.inf, 4.0],
                   [5.0, 6.0, 7.0]])
point_cloud = PointCloud.from_array(points)

Check which points are finite using the is_finite() method.

finite_mask = point_cloud.is_finite()
print(finite_mask)
# Output: [ True False False  True]
