QPolygonOffset Class
(Qt3DRender::QPolygonOffset)The QPolygonOffset class sets the scale and steps to calculate depth values for polygon offsets. More...
| Header: | #include <QPolygonOffset> |
| qmake: | QT += 3drender |
| Since: | Qt 5.7 |
| Instantiated By: | PolygonOffset |
| Inherits: | Qt3DRender::QRenderState |
This class was introduced in Qt 5.7.
Properties
- depthSteps : float
- scaleFactor : float
Public Functions
| QPolygonOffset(Qt3DCore::QNode *parent = nullptr) | |
| float | depthSteps() const |
| float | scaleFactor() const |
Public Slots
| void | setDepthSteps(float depthSteps) |
| void | setScaleFactor(float scaleFactor) |
Signals
| void | depthStepsChanged(float depthSteps) |
| void | scaleFactorChanged(float scaleFactor) |
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) |
