In fsbrain: Managing and Visualizing Brain Surface Data

Remove all faces that use one of the given vertices and renumber the remaining ones.

Description

Filter the faces of a mesh and renumber the vertex indices to refer to the reduced vertex list.

Usage

mesh.atlas.restrict.faces(faces, keep_mask)

Arguments

faces	integer matrix, one face per column, holding 1-based indices into the vertex list.
keep_mask	logical vector, one entry per vertex of the mesh, TRUE for the vertices which are kept.

Value

integer matrix like faces, with all faces removed that used a vertex which is not kept, and with the remaining vertex indices renumbered to refer to which(keep_mask).
