get_brain_mesh: Get brain surface mesh

Description

Retrieves a brain surface mesh for the specified hemisphere and surface type. By default, provides the inflated fsaverage5 surface from internal data. Other surfaces (pial, white, semi-inflated) require the ggseg3d package.

Usage

get_brain_mesh(
  hemisphere = c("lh", "rh"),
  surface = "inflated",
  brain_meshes = NULL
)

Value

A list with vertices (data.frame with x, y, z) and faces

(data.frame with i, j, k), or NULL if the mesh is not available.

Arguments

hemisphere

"lh" or "rh"

surface

Surface type (default "inflated"). Other surfaces require ggseg3d or a custom brain_meshes argument.

brain_meshes

Optional user-supplied mesh data. Accepts either list(lh = list(vertices, faces), rh = ...) or the legacy list(lh_inflated = list(vertices, faces), ...) format.

Examples

mesh <- get_brain_mesh("lh")
head(mesh$vertices)
