详细描述

The QPolygonOffset class sets the scale and steps to calculate depth values for polygon offsets.

A QPolygonOffset class adds an offset to the fragment depth value prior to depth test and depth write. The offset can be used to avoid z-fighting when rendering polygons with very close depth values such as decals.

depthSteps : float

Holds the units that create constant depth offsets. Default value is 0.

访问函数：

float	depthSteps () const
void	setDepthSteps (float depthSteps )

通知程序信号：

void	depthStepsChanged (float depthSteps )

scaleFactor : float

Holds the scale factor used to create a variable depth offset for each polygon. Default value is 0.

访问函数：

float	scaleFactor () const
void	setScaleFactor (float scaleFactor )
