A disp3D scene can be displayed either in a single interactive viewport or in a 2x2 multi-view grid. DISP3DLIB::SubView holds the per-pane camera state — preset (Top / Left / Front / Perspective), zoom, pan offset and rotation quaternion — and DISP3DLIB::ViewVisibilityProfile holds the per-pane visibility mask (hide skin in the cortex view, hide dipoles in the sensor view, ...).

Both structs are POD-like and round-trip through QSettings so the user's last camera and per-pane filter are restored when the host application is relaunched.
