Detailed Description

The controls are:

InputAction
Left mouse buttonWhile the left mouse button is pressed, mouse movement along x-axis moves the camera left and right and movement along y-axis moves it up and down.
Right mouse buttonWhile the right mouse button is pressed, mouse movement along x-axis pans the camera around the camera view center and movement along y-axis tilts it around the camera view center.
Both left and right mouse buttonWhile both the left and the right mouse button are pressed, mouse movement along y-axis zooms the camera in and out without changing the view center.
Mouse scroll wheelZooms the camera in and out without changing the view center.
Arrow keysMove the camera vertically and horizontally relative to camera viewport.
Page up and page down keysMove the camera forwards and backwards.
Shift keyChanges the behavior of the up and down arrow keys to zoom the camera in and out without changing the view center. The other movement keys are disabled.
Alt keyChanges the behovior of the arrow keys to pan and tilt the camera around the view center. Disables the page up and page down keys.
EscapeMoves the camera so that entire scene is visible in the camera viewport.

Property Documentation

inversePan : bool

Holds whether panning is inverted.

When enabled, horizontal pan movements rotate the camera around the view center in the opposite direction.

Access functions:

bool inversePan() const
void setInversePan(bool isInverse)

Notifier signal:

void inversePanChanged(bool isInverse)

inverseTilt : bool

Holds whether tilting is inverted.

When enabled, vertical tilt movements rotate the camera around the view center in the opposite direction.

Access functions:

bool inverseTilt() const
void setInverseTilt(bool isInverse)

Notifier signal:

void inverseTiltChanged(bool isInverse)

inverseXTranslate : bool

Holds whether the horizontal translation is inverted.

When enabled, horizontal mouse movements and input translate the camera in the opposite direction.

Access functions:

bool inverseXTranslate() const
void setInverseXTranslate(bool isInverse)

Notifier signal:

void inverseXTranslateChanged(bool isInverse)

inverseYTranslate : bool

Holds whether the vertical translation is inverted.

When enabled, vertical mouse movements and input translate the camera in the opposite direction.

Access functions:

bool inverseYTranslate() const
void setInverseYTranslate(bool isInverse)

Notifier signal:

void inverseYTranslateChanged(bool isInverse)

upVector : QVector3D

Holds the up vector for the camera's orbital rotation.

The up vector defines the vertical axis around which the camera orbits. The default value is (0.0, 1.0, 0.0).

Access functions:

QVector3D upVector() const
void setUpVector(const QVector3D &upVector)

Notifier signal:

void upVectorChanged(const QVector3D &upVector)

zoomInLimit : float

Holds the current zoom-in limit. The zoom-in limit determines how close to the view center the camera can be zoomed.

Access functions:

float zoomInLimit() const
void setZoomInLimit(float zoomInLimit)

Notifier signal:

void zoomInLimitChanged()

zoomTranslateViewCenter : bool

Holds whether the view center is translated during zoom operations.

When enabled, zooming translates the view center. When disabled, only the camera position changes during zoom operations. The default value is true.

Access functions:

bool zoomTranslateViewCenter() const
void setZoomTranslateViewCenter(bool isTranslate)

Notifier signal:

void zoomTranslateViewCenterChanged(bool isTranslate)
