resolve_brain_mesh: Resolve brain surface mesh

In ggseg3d: Interactive 3D Brain Atlas Visualization

Resolve brain surface mesh

Description

Resolves and prepares a brain surface mesh for rendering. Delegates to [ggseg.formats::get_brain_mesh()] for inflated surfaces, provides pial, white, and semi-inflated surfaces from ggseg3d internal data, corrects 0-based face indices, and centers inflated/semi-inflated meshes on pial centroids.

Usage

resolve_brain_mesh(
  hemisphere = c("lh", "rh"),
  surface = c("inflated", "semi-inflated", "white", "pial"),
  brain_meshes = NULL
)

Arguments

hemisphere	'"lh"' or '"rh"'
surface	Surface type: '"inflated"', '"semi-inflated"', '"white"', '"pial"'
brain_meshes	Optional user-supplied mesh data. Passed through to [ggseg.formats::get_brain_mesh()] for format details.

Value

list with vertices (data.frame with x, y, z) and faces (data.frame with i, j, k), or NULL if mesh not found
