irtk.metric.chamfer_distance

irtk.metric.chamfer_distance(mesh_a_: str | Dict, mesh_b_: str | Dict, num_samples: int, mode: Literal['forward', 'backward', 'bidirectional'] = 'bidirectional') → float

Computes the Chamfer Distance (CD) between two meshes.

Parameters:

  • mesh_a – One mesh specified by file name or a dict containing ‘v’ and ‘f’.

  • mesh_b – Another mesh specified by file name or a dict containing ‘v’ and ‘f’.

  • num_samples – Number of samples to compute Chamfer Distance.

  • mode – The sample mode. Supports ‘forward’, ‘backward’, and ‘bidirectional’.

Returns:

The Chamfer Distance between the two meshes.
