vcgIsolated {Rvcg}

Remove isolated pieces from a surface mesh or split into connected components

Description

Remove isolated pieces from a surface mesh, selected by a minimum amount of faces or of a diameter below a given threshold. Also the option only to keep the largest piece can be selected or to split a mesh into connected components.

Usage

vcgIsolated(
  mesh,
  facenum = NULL,
  diameter = NULL,
  split = FALSE,
  keep = 0,
  silent = FALSE
)

Arguments

mesh

triangular mesh of class "mesh3d".

facenum

integer: all connected pieces with less components are removed. If not specified or 0 and diameter is NULL, then only the component with the most faces is kept.

diameter

numeric: all connected pieces smaller diameter are removed removed. diameter = 0 removes all component but the largest ones. This option overrides the option facenum.

split

logical: if TRUE, a list with all connected components (optionally matching requirements facenum/diameter) of the mesh will be returned.

keep

integer: if split=T, keep specifies the number of largest chunks (number of faces) to keep.

silent

logical, if TRUE no console output is issued.

Value

returns the reduced mesh.
