get_bounding_box_points

k3d.helpers.get_bounding_box_points(arr, model_matrix)

Return the minimum and maximum coordinates on x, y, z axes.

Parameters

• arr (ndarray) – Array of vertices [x, y, z].

• model_matrix (ndarray) – Matrix of numbers. Must have four columns.

Returns

Array of numbers [min_x, max_x, min_y, max_y, min_z, max_z].

Return type

ndarray
