view_label3d

With camera-based views, geometry (and text) stays in world
coordinates while the camera applies the view rotation. To keep a label at
the same screen position relative to the (now unrotated) renderables as in
the legacy mesh-rotation views, the label offset is pre-rotated by the
view's mesh rotation matrix R_mesh.

Provides high-level access to neuroimaging data from standard software packages like 'FreeSurfer' <https://freesurfer.net/> on the level of subjects and groups. Load morphometry data, surfaces and brain parcellations based on atlases. Mask data using labels, load data for specific atlas regions only, and visualize data and statistical results directly in 'R'.
