详细描述

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.

特性文档编制

gamma : float

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

访问函数：

float	gamma () const
void	setGamma (float gamma )

通知程序信号：

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.

访问函数：

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

通知程序信号：

void	normalizedRectChanged (const QRectF & normalizedRect )
