build_tract_meshes

Creates mesh data structures for tract atlases with per-vertex colouring.
Supports palette colours (uniform per tract) or orientation-based RGB
colours computed from centerline tangent vectors.

internal

Plot brain atlases as interactive 3D meshes using 'Three.js'
via 'htmlwidgets', 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 or ray-trace the result. Additional
atlases are available through the 'ggsegverse' r-universe. Mowinckel
