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.
