Interactive 3D Brain Atlas Visualization.

ggseg3d

Interactive 3D brain atlas visualization in R. Plot brain parcellations as WebGL meshes powered by Three.js, or render publication-quality static images through rgl and rayshader. A pipe-friendly API lets you map data onto brain regions, control camera angles, toggle region edges, overlay glass brains, and snapshot the result.

Installation

Install from CRAN:

install.packages("ggseg3d")

Or get the development version from the ggsegverse r-universe:

options(
  repos = c(
    ggsegverse = "https://ggsegverse.r-universe.dev",
    CRAN = "https://cloud.r-project.org"
  )
)
install.packages("ggseg3d")

Atlases

Three atlases ship with the package (via ggseg.formats):

1. dk – Desikan-Killiany cortical atlas
2. aseg – Automatic subcortical segmentation
3. tracula – White-matter tract atlas

Additional atlases are available through the ggsegverse r-universe.

Usage

ggseg3d(atlas = dk(), hemisphere = "left") |>
  pan_camera("left lateral")

Subcortical structures with a translucent glass brain overlay:

ggseg3d(atlas = aseg()) |>
  add_glassbrain() |>
  pan_camera("right lateral")

See the package website for the full walkthrough, rayshader rendering, and Shiny integration.
