## 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.

## Property Documentation

### 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)
