closest.vert.to.point {freesurferformats}

Find vertex index closest to given query coordinate using Euclidean distance.

Description

Find vertex index closest to given query coordinate using Euclidean distance.

Usage

closest.vert.to.point(surface, point_coords)

Arguments

surface

an fs.surface instance or a nx3 numerical matrix representing mesh points.

point_coords

nx3 matrix of query coords. If a vector, will be transformed byrow to such a matrix.

Value

named list with entries: 'vertex_id' integer vector, the index of the closest vertex, and 'dist': double vector, the Euclidean distance to that vertex.
