SubView

Namespace: DISP3DLIB  ·  Library: 3D Display Library

#include <disp3D/viewstate.h>

struct DISP3DLIB::SubView

Viewport subdivision holding its own camera, projection, and scissor rectangle.

Encapsulates all per-view state for a single viewport (single view or one pane in multi-view).

The class stores shader, surface type, overlay mode, visibility flags, zoom, pan, camera rotation, and view preset — everything that can differ between two viewports showing the same scene.

Public Methods​

matchesSurfaceType(key)​

True when the brain-surface key matches this view's surfaceType (e.g.

"lh_pial" matches surfaceType "pial").

Parameters:

  • key : const QString & Surface map key to test.

Returns:

  • bool — True if the key is a brain surface key ending with surfaceType.

shouldRenderSurface(key)​

True when the surface identified by key should be rendered according to this view's visibility profile.

Parameters:

  • key : const QString & Surface map key to test.

Returns:

  • bool — True if the visibility profile enables this surface; unknown keys return true.

applyOverlayToSurfaces(surfaces)​

Apply this view's overlayMode to every brain surface whose key matches surfaceType.

Non-brain surfaces are never touched.

Parameters:

  • surfaces : QMap< QString, std::shared_ptr< BrainSurface > > & Surface map keyed by surface name; matching surfaces get their visualization mode updated.

load(settings, prefix, fallbackRotation)​

Load this SubView's state from QSettings under the given prefix.

Parameters:

  • settings : const QSettings & Settings store to read from.

  • prefix : const QString & Key prefix (e.g. "multi0_").

  • fallbackRotation : const QQuaternion & Rotation to use if no saved quaternion exists.

save(settings, prefix)​

Save this SubView's state to QSettings under the given prefix.

Parameters:

  • settings : QSettings & Settings store to write to.

  • prefix : const QString & Key prefix (e.g. "multi0_").

Static Methods​

isBrainSurfaceKey(key)​

True when key identifies a brain-tissue surface (lh_/rh_) as opposed to BEM, sensor, digitizer, or source-space geometry.

Parameters:

  • key : const QString & Surface map key to classify.

Returns:

  • bool — True if the key is non-empty and has no bem_, sens_, srcsp_ or dig_ prefix.

defaultForIndex(index)​

Return default SubView configuration for viewport index.

The preset cycles through the 7 camera orientations (Top, Perspective, Front, Left, Bottom, Back, Right) and the shader cycles through Anatomical → Standard → Holographic.

Parameters:

  • index : int Zero-based viewport index.

Returns:

  • SubView — Enabled SubView with preset index % 7 and the cycled brain shader.
