Detailed Description

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.

Property Documentation

depthSteps : float

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

Access functions:

float	depthSteps() const
void	setDepthSteps(float depthSteps)

Notifier signal:

void	depthStepsChanged(float depthSteps)

scaleFactor : float

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