BrainView is the public face of disp3D — the QWidget that any host application embeds to get an interactive cortical / sensor / source scene. It connects DISP3DLIB::BrainTreeModel data changes to scene rebuilds, drives DISP3DLIB::CameraController from the Qt mouse / wheel events, switches between single- and multi-view layouts through DISP3DLIB::MultiViewLayout and delegates the actual drawing to DISP3DLIB::BrainRenderer.

Live overlays such as digitizer tracker markers or AR avatars are exposed through the lightweight DISP3DLIB::LiveMarker struct so the host GUI can spray transient annotations on the scene without going through the tree model.
