Detailed Description

Camera state and matrix computation.

Encapsulates camera state and produces view/projection matrices.

This class is independent of any Qt widget — it takes scene geometry parameters and view configuration, and produces camera matrices. It also handles rotation, zoom, and pan from mouse delta values.

applyMousePan()

void CameraController::applyMousePan ( const QPoint & delta, QVector2D & pan, float sceneSize )

static

Apply pan from mouse drag delta (planar multi-view pane).

Parameters

[in]	delta	Mouse delta in pixels.
[in,out]	pan	Pan offset to update.
[in]	sceneSize	Current scene size for scaling.

Definition at line 137 of file cameracontroller.cpp.

applyMouseRotation()

void CameraController::applyMouseRotation ( const QPoint & delta, QQuaternion & rotation, float speed = 0.5f )

static

Apply rotation from mouse drag delta (single-view or perspective pane).

Parameters

[in]	delta	Mouse delta in pixels.
[in,out]	rotation	Rotation quaternion to update.
[in]	speed	Rotation speed multiplier (default 0.5).

[in]	aspectRatio	Width / height of the pane.

Returns

CameraResult with all matrices.
