MeshAgreement (version 0.1.4)

get_mesh_metro: Distances between two 3D meshes

Description

Calculate the distance maps between all pairs from a list of 3D meshes. Used for distance-based agreement measures such as the Hausdorff distance or the average surface distance.

Usage

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

Value

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

Arguments

x

list of observer/mesh objects as generated by read_mesh.

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_pair to process a single mesh pair. Calculating agreement measures for all pairs for a list of 3D meshes is done in get_mesh_agree.
