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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property depthStepsᅟ: float#

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

Access functions:

depthSteps()
setDepthSteps()
Signal depthStepsChanged()

property scaleFactorᅟ: float#

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

Access functions:

scaleFactor()
setScaleFactor()
Signal scaleFactorChanged()

__init__([parent=None])#

Parameters:: parent – QNode
