pysnt.converters.tree_converters module#

Tree conversion utilities for PySNT.

This module provides functions to convert SNT Tree objects into Python data structures.

tree_to_points(tree)[source]#

Extract node coordinates from a Tree as a numpy array.

This is a convenience function that extracts the numpy array directly. Tree objects are also automatically converted when using pysnt.to_python(), which returns the same numpy array.

Parameters:: tree (Tree) – PySNT Tree object
Returns:: Array of shape (N, 3) containing XYZ coordinates
Return type:: np.ndarray

Examples

>>> from pysnt.converters.tree_converters import tree_to_points
>>> points = tree_to_points(tree)
>>> print(points.shape)  # (N, 3)

>>> # Automatic conversion via pysnt.to_python() returns the same array:
>>> points = pysnt.to_python(tree)  # Same numpy array result
>>> print(points.shape)  # (N, 3)

Notes

The difference between this function and pysnt.to_python(tree): - tree_to_points(tree): Returns numpy array directly - pysnt.to_python(tree): Also returns numpy array (via registered converter) - _convert_tree_to_points(tree): Returns SNTObject dict (internal use only)
