vcgIsolated

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.
