MeshAgreement (version 0.1.4)

get_mesh_metro_pair: Distances between two 3D meshes

Description

Calculate distances between two 3D meshes. Used for distance-based agreement measures such as the Hausdorff distance or the average surface distance.

Usage

get_mesh_metro_pair(x, chop=TRUE, ...)

Value

list with object returned by vcgMetro together with the name of the comparison and a name for the structure.

Arguments

x

list of two 3D meshes that should be compared, e.g., a single component of the list generated by get_mesh_pairs.

chop

logical. Delete the components from output of vcgMetro that will not be used later on.

...

Options passed to vcgMetro.

Details

Thin front-end for vcgMetro. Use get_mesh_metro to process all pairs from a list of 3D meshes. Post-processing for agreement measures is done in get_mesh_agree_pair.
