Construct a packed cortical surface feature space

Usage

surface_space(
  vertex_ids,
  hemisphere,
  support = NULL,
  topology = NULL,
  geometry = NULL,
  medial_wall = NULL,
  template = NULL,
  units = "mm",
  surf_to_world = diag(4),
  metadata = list()
)

Arguments

vertex_ids: Stable IDs for every vertex in the full mesh.
hemisphere: One "left" or "right" label per full-mesh vertex.
support: Active vertex positions or IDs. By default, all non-medial-wall vertices are active.
topology: A three-column face matrix or asset descriptor with reference, digest, and optional data/faces.
geometry: A vertex-by-three coordinate matrix or asset descriptor with reference, digest, and optional data/coordinates.
medial_wall: Logical full-mesh medial-wall mask.
template: Optional template identity such as "fsLR-32k".
units: Coordinate units.
surf_to_world: A finite 4 by 4 surface-to-world transform, following the neurosurf::SurfaceGeometry convention.
metadata: Additional serializable metadata.

Value

A surface_space.

  vertex_ids = c("L-1", "L-2", "L-3"),
