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

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