add_glassbrain: Add glass brain to ggseg3d plot

Description

Adds a translucent brain surface to a ggseg3d plot for anatomical reference. Particularly useful for subcortical and tract visualizations where spatial context helps interpretation. Works with both htmlwidget (`ggseg3d`) and rgl (`ggsegray`) objects.

Usage

add_glassbrain(
  p,
  hemisphere = c("left", "right"),
  surface = "pial",
  colour = "#CCCCCC",
  opacity = 0.3,
  brain_meshes = NULL
)

Value

The input object (modified), for piping.

Arguments

p

A `ggseg3d` widget or `ggsegray` rgl object.

hemisphere

Character vector. Hemispheres to add: "left", "right", or both.

surface

Character. Surface type: "inflated", "white", or "pial".

colour

Character. Colour for the glass brain surface (hex or named).

opacity

Numeric. Transparency of the glass brain (0-1).

brain_meshes

Optional user-supplied brain meshes. See [ggseg.formats::get_brain_mesh()] for format details.

Examples

if (FALSE) {
ggseg3d(atlas = aseg()) |>
  add_glassbrain("left", opacity = 0.2)

ggsegray(atlas = aseg()) |>
  add_glassbrain(opacity = 0.15) |>
  pan_camera("right lateral")
}
