Detailed Description

Qt 3D Studio presentation viewer settings.

Q3DSViewerSettings provides properties to define presentation-independent viewer settings.

Note: This class should not be instantiated directly when working with the C++ APIs. Q3DSSurfaceViewer creates a Q3DSViewerSettings instance implicitly. This can be queried via Q3DSSurfaceViewer::settings().

Member Type Documentation

enum Q3DSViewerSettings::ScaleMode

This enumeration specifies the possible scaling modes.

ConstantValueDescription
Q3DSViewerSettings::ScaleModeFit0Scales the presentation to fit the output area.
Q3DSViewerSettings::ScaleModeFill1Scales the presentation to completely fill the output area. This is the default.
Q3DSViewerSettings::ScaleModeCenter2Centers the presentation in the output area without scaling it.

enum Q3DSViewerSettings::ShadeMode

enum Q3DSViewerSettings::StereoMode

Property Documentation

matteColor : QColor

Specifies the matte color.

Access functions:

QColor matteColor() const
void setMatteColor(const QColor &color)

Notifier signal:

void matteColorChanged(const QColor &color)

matteEnabled : bool

Specifies if the empty area around the presentation (applicable when scaleMode is set to ScaleModeCenter or ScaleModeFit) should be filled with a custom color.

The default value is false.

Access functions:

bool matteEnabled() const
void setMatteEnabled(bool enabled)

Notifier signal:

void matteEnabledChanged(bool enabled)

See also matteColor.

scaleMode : ScaleMode

Specifies the scaling mode. The default value is ScaleModeFill where the size of the presentation on-screen follows and fills the size of the output area (the window, the screen, or the area occupied by the Studio3D element).

During the design phase it can be valuable to see the presentation with some other scaling approach. For example, the Qt 3D Studio Viewer application uses ScaleModeCenter by default.

ConstantDescription
ScaleModeFitScales the presentation to fit the output area.
ScaleModeFillScales the presentation to completely fill the output area.
ScaleModeCenterCenters the presentation in the output area without scaling it.

The default value is ScaleModeFill.

Access functions:

Q3DSViewerSettings::ScaleMode scaleMode() const
void setScaleMode(Q3DSViewerSettings::ScaleMode mode)

Notifier signal:

void scaleModeChanged(Q3DSViewerSettings::ScaleMode mode)

showRenderStats : bool

When this property is true, the simple profile view is displayed in-scene, on top of the 3D content.

Note: This feature can be disabled at build time, in which case this property has no effect.

Default value is false.

Access functions:

bool isShowRenderStats() const
void setShowRenderStats(bool show)

Notifier signal:

void showRenderStatsChanged(bool show)

stereoEyeSeparation : double

Specifies the eye (camera) separation of stereo rendering. Value is the amount left and right eye cameras move in x-coordinate values away from center. Bigger separation increases the 3D effect. Optimal value depends on viewed presentation.

This has only effect when stereo mode is set to something else than default StereoModeMono.

This property was introduced in Qt 3D Studio 2.5.

Access functions:

double stereoEyeSeparation() const
void setStereoEyeSeparation(double separation)

Notifier signal:

void stereoEyeSeparationChanged(double separation)

stereoMode : StereoMode

Specifies the stereo mode. The default value is StereoModeMono where the view is rendered normally, as suitable for 2D displays. Other available modes target different 3D stereo rendering types.

ConstantDescription
StereoModeMonoRenders presentation normally in mono.
StereoModeTopBottomRenders presentation in stereoscopic top-bottom mode.
StereoModeLeftRightRenders presentation in stereoscopic left-right mode.
StereoModeAnaglyphRedCyanRenders presentation in anaglyph red-cyan mode.
StereoModeAnaglyphGreenMagentaRenders presentation in anaglyph green-magenta mode.

The default value is StereoModeMono.

This property was introduced in Qt 3D Studio 2.5.

Access functions:

Q3DSViewerSettings::StereoMode stereoMode() const
void setStereoMode(Q3DSViewerSettings::StereoMode mode)

Notifier signal:

void stereoModeChanged(Q3DSViewerSettings::StereoMode mode)

Member Function Documentation

void Q3DSViewerSettings::load(const QString &group, const QString &organization = QString(), const QString &application = QString())

Loads previously saved viewer settings using group, organization and application.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void Q3DSViewerSettings::save(const QString &group, const QString &organization = QString(), const QString &application = QString())

Persistently saves the viewer settings using group, organization and application.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
