ThresholdEffect is a post-processing effect that passes through any pixel above a certain brightness value and sets all others to black.
#include <Qt3DExtras/Qt3DWindow> #include <ForwardRenderer> #include <SceneEntity> #include <ThresholdEffect> Qt3DExtras::Qt3DWindow win; Kuesa::SceneEntity *root = new Kuesa::SceneEntity(); Kuesa::ForwardRenderer *frameGraph = new Kuesa::ForwardRenderer(); Kuesa::ThresholdEffect *thresholdEffect = new Kuesa::ThresholdEffect(); thresholdEffect->setThreshold(0.5f); frameGraph->addPostProcessingEffect(thresholdEffect); win->setRootEntity(root); win->setActiveFrameGraph(forwardRenderer); ...
This property holds the brightness value used as a cut-off
This value is used to determine how bright a pixel needs to be to pass the threshold.
| Threshold 0.12 | Threshold 0.35 |

[slot] void ThresholdEffect::setThreshold(float threshold)Sets the threshold value to threshold.
Note: Setter function for property threshold.

[override virtual] Kuesa::AbstractPostProcessingEffect::FrameGraphNodePtr ThresholdEffect::frameGraphSubTree() constReturns the frame graph subtree corresponding to the effect's implementation.
See also AbstractPostProcessingEffect::frameGraphSubTree.
[override virtual] void ThresholdEffect::setInputTexture(Qt3DRender::QAbstractTexture *texture)Sets the input texture for the effect to texture.
See also AbstractPostProcessingEffect::setInputTexture().
Returns the current threshold.
Note: Getter function for property threshold.
