New ggsegverse update!

I finally got around to pre-release new ggseg.extra (notice name change) package, for creating new atlases.

Cerebellar flatmaps now in #ggsegverse!

We have now shipped across the ggsegverse the possibility to visualise the cerebellum parcellations also, based on the SUIT flatmap from the Diedriksen lab.

ggseg now draws brains without sf.

It installs needing compiled GDAL, GEOS, or PROJ — so it runs on locked-down laptops, HPC clusters, and in the browser (webR/shinylive). Same geom_brain(), identical figures.

ggseg 2.0: One atlas object for both 2D and 3D brain visualization.

In v1, you loaded `dk` for 2D and `dk_3d` for 3D.

That's gone. One call — dk() — feeds both renderers.

It's full of new features, and likely lots of new bugs.
I'd love folks to test how it works, I've really tried making things more robust and I hope its payed off!

*Cortical atlases store vertex indices, not mesh geometry* — Each region is a vector of integers into a shared fsaverage5 mesh. Atlas packages shrink. Rendering loads one mesh per hemisphere instead of dozens.

The #ggsegverse website how has a proper playground! Served through @posit.co Cloud Connect, a n #rstats session to explore atlases, how to alter their positions, colours etc. An excellent resource to also learn how to use it, as it shows the code. #shiny

The demo app in 2D view. A sidebar on the left holds the atlas picker, a Colour regions by radio set with Example values selected, a Viridis colour scale, a seed slider, and layout and theme pickers. The main panel shows the Desikan-Killiany atlas drawn in eight views, two rows of four, each region filled from a viridis scale. Below the figure a code panel titled The code behind this figure shows the R script that made it, beginning with library(ggseg) and library(ggplot2). The demo app in 3D view. The sidebar offers Surface, Hemispheres, Add glass brain, Camera and Background controls. The main panel shows an inflated left hemisphere seen from the lateral side, each cortical region a different colour, with a region legend to the right. The code panel below reads library(ggseg3d), then a ggseg3d call with atlas and surface arguments piped into pan_camera and set_background.

*Pipe-friendly atlas manipulation* — atlas_region_keep(), atlas_view_keep(), and friends filter, rename, and reorder regions. Output goes straight to geom_brain().

New CRAN package ggseg.meshes with initial version 0.0.1
#rstats
https://cran.r-project.org/package=ggseg.meshes
CRAN: Package ggseg.meshes
Provides additional brain surface meshes for cortical and cerebellar visualisation in the 'ggsegverse' ecosystem. Cortical surfaces include pial, white, midthickness, semi-inflated, sphere, smoothwm, and orig at fsaverage5 resolution. Cerebellar surfaces include the Spatially Unbiased Infratentorial Template (SUIT) flatmap. All meshes follow the same vertices/faces data frame format used by 'ggseg.formats' and 'ggseg3d'.

*3D engine rebuilt on Three.js* — Plotly is out. Three.js through htmlwidgets gives orthographic projection, glassbrain overlays, flat shading for exact color matching, and standard anatomical camera positions.

*Tract atlases in 3D* — White matter tracts had no 3D representation in v1. They do now.

What's new:

*Unified atlas format* — A single ggseg_atlas class carries sf geometries, vertex indices, region metadata, and color palettes. Both geom_brain() and ggseg3d() read the same object.
