Get SUIT cerebellar flatmap mesh — get_cerebellar

Retrieves the SUIT cerebellar flatmap surface mesh. This is a 2D flattened representation of the cerebellar cortex, useful for visualising cerebellar parcellations without 3D rendering.

Usage

get_cerebellar_flatmap(surface = .cerebellar_surfaces)

Arguments

surface: Surface type. Currently only "suit_flat".

Value

A list with vertices (data.frame with x, y, z) and faces (data.frame with i, j, k, 0-based indices matching ggseg.formats convention for cerebellar meshes). Has attribute face_index_base = 0L.

Details

The flatmap has z-coordinates near zero (flat projection). Vertex count matches the SUIT 3D pial surface in ggseg.formats, so vertex indices from cerebellar atlases map directly to this mesh.

Examples

mesh <- get_cerebellar_flatmap()
nrow(mesh$vertices)
