## Detailed Description

The QFrontFace class defines front and back facing polygons.

A Qt3DRender::QFrontFace sets the winding direction of the front facing polygons.

See also QCullFace.

## Member Type Documentation

### enum QFrontFace::WindingDirection

This enumeration specifies the winding direction values.

Constant | Value | Description
--- | --- | ---
`Qt3DRender::QFrontFace::ClockWise` | `0x0900` | Clockwise polygons are front facing.
`Qt3DRender::QFrontFace::CounterClockWise` | `0x0901` | Counter clockwise polygons are front facing.

## Property Documentation

### direction : WindingDirection

Holds the winding direction of the front facing polygons. Default is Clockwise.

Access functions:

WindingDirection | direction() const
void | setDirection(WindingDirection direction)

Notifier signal:

void | directionChanged(WindingDirection direction)

## Member Function Documentation

### QFrontFace::QFrontFace(Qt3DCore::QNode *parent = nullptr)

Default constructs an instance of QFrontFace.
