differt.geometry.path_lengths

path_lengths(paths)

Compute the path length of each path.

Each path is exactly made of path_length vertices.

Parameters:

paths (Float[ArrayLike, '*batch path_length 3']) – The array of path vertices.

Return type:

Float[Array, '*batch']

Returns:

The array of path lengths.

Examples

The following example shows how to compute the length of a very simple path.

>>> from differt.geometry import (
...     path_lengths,
... )
>>>
>>> path = jnp.array([[1.0, 0.0, 0.0], [1.0, 1.0, 0.0]])
>>> path_lengths(path)
Array(1., dtype=float32)
>>> path_lengths(jnp.vstack((path, path[::-1, :])))
Array(2., dtype=float32)
