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.
Access functions:
float | scaleFactor() const |
void | setScaleFactor(float scaleFactor) |
Notifier signal:
void | scaleFactorChanged(float scaleFactor) |
Member Function Documentation
QPolygonOffset::QPolygonOffset(Qt3DCore::QNode *parent = nullptr)
