Visualize fs.surface mesh — vis.fs.surface • fsbrain

Render a mesh. All mesh formats supported by the freesurferformats package are supported, including OFF, PLY, OBJ, STL, and many more.

Usage

vis.fs.surface(
  fs_surface,
  col = "white",
  per_vertex_data = NULL,
  hemi = "lh",
  makecmap_options = mkco.seq(),
  ...
)

fs_surface: an fs.surface instance, as returned by function like subject.surface or read.fs.surface. If a character string, it is assumed to be the full path of a surface file, and the respective file is loaded with read.fs.surface. If parameter 'hemi' is 'both', this must be a hemilist. A single rgl::tmesh is also fine.
col: vector of colors, the per-vertex-colors. Defaults to white. Must be a single color or one color per vertex. If parameter 'hemi' is 'both', this must be a hemilist.
per_vertex_data: numerical vector, per-vertex data. If given, takes precedence over 'col'. Used to color the mesh using the colormap options in parameter 'makecmap_options'. If a character string, it is assumed to be the full path of a morphometry data file, and the respective file is loaded with read.fs.morph. If parameter 'hemi' is 'both', this must be a hemilist.
hemi: character string, one of 'lh' or 'rh'. This may be used by visualization functions to decide whether or not to show this mesh in a certain view.
makecmap_options: named list of parameters to pass to makecmap. Must not include the unnamed first parameter, which is derived from 'measure'. Should include at least a colormap function as name 'colFn'.
...: extra parameters to pass to vis.coloredmeshes.

This function can be used to visualize arbitrary triangular meshes in R. Despite its name, it is not limited to brain surface meshes.
