Detailed Description

A viewport on the Qt3D Scene

Qt3DRender::QViewport of the scene specifies at which portion of the render surface Qt3D is rendering to. Area outside the viewport is left untouched. It also controls global parameters to the rendering in that viewport like gamma.

Property Documentation

gamma : float

Specifies the gamma factor for the viewport. The default is 2.2 which should give proper result on most screens.

Access functions:

float gamma() const
void setGamma(float gamma)

Notifier signal:

void gammaChanged(float gamma)

normalizedRect : QRectF

Specifies the normalised rectangle for the viewport, i.e. the viewport rectangle is specified relative to the render surface size. Whole surface sized viewport is specified as [0.0, 0.0, 1.0, 1.0], which is the default.

Access functions:

QRectF normalizedRect() const
void setNormalizedRect(const QRectF &normalizedRect)

Notifier signal:

void normalizedRectChanged(const QRectF &normalizedRect)

Member Function Documentation

QViewport::QViewport(Qt3DCore::QNode *parent = nullptr)

Constructs QViewport with given parent.
