Classes

PointCloud(points)

Point cloud data structure with internal gridding for ball and nearest neighbor queries.

class neurots.astrocyte.point_cloud.PointCloud(points)

Bases: object

Point cloud data structure with internal gridding for ball and nearest neighbor queries.

The points that are removed are not removed from memory, but invalidated.

Parameters:

• point_array (np.ndarray) – Array of 3D points to store in the point cloud.

• cutoff_radius (float) – The radius from which the bin size of the grid will be calculated.

• removal_radius (float) – Radius that will be used for default removal. See attribute below.

default_removal_radius

A default radius that will be used for the remove_points_around if an explicit value is not passed in the method.

Type:

float

default_radius_of_influence

A default radius for the calculation of the average direction if an explicit value is not passed in the method.

Type:

float

property available_ids

Returns ids of available points.

property available_points

Returns available points.

ball_query(point, radius)

Ball query around point with radius.

nearest_neighbor(point, radius)

Get the nearest neighbor to the point with cuttoff radius.

nearest_neighbor_direction(point, radius)

Get nearest neighbor direction.

partial_ball_query(point, radius, direction, cap_angle_front, cap_angle_back)

Truncated ball query.

property points

Returns point cloud points.

remove_hemisphere(point, direction, radius)

Remove hemisphere that points to direction.

remove_ids(point_ids)

Remove points ids.

remove_points_around(point, radius)

Remove the points in the sphere located at point with removal_radius.

property removed_ids

Returns ids of removed points.

property removed_points

Returns removed points.

upper_half_ball_query(point, radius, direction)

Hemisphere query around point directed to direction.
