Q3DCamera Class

Property Documentation

cameraPreset : CameraPreset

This property holds the currently active camera preset.

If no CameraPreset value is set, CameraPresetNone is used by default.

Access functions:

Q3DCamera::CameraPreset	cameraPreset() const
void	setCameraPreset(Q3DCamera::CameraPreset preset)

Notifier signal:

void	cameraPresetChanged(Q3DCamera::CameraPreset preset)

maxZoomLevel : float

This property holds the maximum allowed camera zoom level.

If the maximum level is set to a new value that is lower than the existing minimum level, the minimum level is adjusted to the new maximum as well. If the current zoomLevel is outside the new bounds, it is adjusted as well. Defaults to 500.0f.

Access functions:

float	maxZoomLevel() const
void	setMaxZoomLevel(float zoomLevel)

Notifier signal:

void	maxZoomLevelChanged(float zoomLevel)

See also zoomLevel and minZoomLevel.

minZoomLevel : float

This property holds the minimum allowed camera zoom level.

If the minimum level is set to a new value that is higher than the existing maximum level, the maximum level is adjusted to the new minimum as well. If the current zoomLevel is outside the new bounds, it is adjusted as well. The minZoomLevel cannot be set below 1.0f. Defaults to 10.0f.

Access functions:

float	minZoomLevel() const
void	setMinZoomLevel(float zoomLevel)

Notifier signal:

void	minZoomLevelChanged(float zoomLevel)

See also zoomLevel and maxZoomLevel.

target : QVector3D

This property holds the camera target as a a vector or vertex in the 3D space.

Defaults to QVector3D(0.0, 0.0, 0.0).

Valid coordinate values are between -1.0...1.0, where the edge values indicate the edges of the corresponding axis range. Any values outside this range are clamped to the edge.

Note: For bar graphs, the Y-coordinate is ignored and camera always targets a point on the horizontal background.

This property was introduced in QtDataVisualization 1.2.

Access functions:

QVector3D	target() const
void	setTarget(const QVector3D &target)

Notifier signal:

void	targetChanged(const QVector3D &target)

wrapXRotation : bool

This property holds the behavior of the minimum and maximum limits in the X-rotation.

If set to true, the X-rotation of the camera is wrapped from minimum to maximum and from maximum to minimum. If set to false, the X-rotation of the camera is limited to the sector determined by the minimum and maximum values. Set to true by default.

Access functions:

bool	wrapXRotation() const
void	setWrapXRotation(bool isEnabled)

Notifier signal:

void	wrapXRotationChanged(bool isEnabled)

wrapYRotation : bool

This property holds the behavior of the minimum and maximum limits in the Y-rotation.

If true, the Y-rotation of the camera is wrapped from minimum to maximum and from maximum to minimum. If false, the Y-rotation of the camera is limited to the sector determined by the minimum and maximum values. Set to true by default.

Access functions:

bool	wrapYRotation() const
void	setWrapYRotation(bool isEnabled)

Notifier signal:

void	wrapYRotationChanged(bool isEnabled)

xRotation : float

This property holds the X-rotation angle of the camera around the target point in degrees.

Access functions:

float	xRotation() const
void	setXRotation(float rotation)

Notifier signal:

void	xRotationChanged(float rotation)

yRotation : float

This property holds the Y-rotation angle of the camera around the target point in degrees.

Access functions:

float	yRotation() const
void	setYRotation(float rotation)

Notifier signal:

void	yRotationChanged(float rotation)

zoomLevel : float

This property holds the camera zoom level in percentage.

The default value of 100.0f means there is no zoom in or out set in the camera. The value is limited by the minZoomLevel and maxZoomLevel properties.

Access functions:

float	zoomLevel() const
void	setZoomLevel(float zoomLevel)

Notifier signal:

void	zoomLevelChanged(float zoomLevel)

See also minZoomLevel and maxZoomLevel.
